Recently, the 2025 Nobel Prize in Chemistry was awarded to Susumu Kitagawa, Richard Robson, and Omar Yaghi in recognition of “their development of metal–organic frameworks (MOFs).”

The three laureates created molecular structures with enormous internal spaces, allowing gases and other chemical species to flow through them. These structures, known as Metal–Organic Frameworks (MOFs), have applications ranging from extracting water from desert air and capturing carbon dioxide, to storing toxic gases and catalyzing chemical reactions.

Metal–Organic Frameworks (MOFs) are a class of crystalline porous materials formed by metal ions or clusters linked via organic ligands (Figure 1). Their structures can be envisioned as a three-dimensional network of “metal nodes + organic linkers,” combining the stability of inorganic materials with the design flexibility of organic chemistry. This versatile construction allows MOFs to be composed of almost any metal from the periodic table and a wide variety of ligands, such as carboxylates, imidazolates, or phosphonates, enabling precise control over pore size, polarity, and chemical environment.

Figure 1. Schematic of a Metal–Organic Framework

Since the first permanent-porosity MOFs appeared in the 1990s, thousands of structural frameworks have been developed, including classic examples like HKUST-1 and MIL-101. They exhibit ultrahigh specific surface areas and pore volumes, offering unique properties for gas adsorption, hydrogen storage, separation, catalysis, and even drug delivery. Some flexible MOFs can undergo reversible structural changes in response to adsorption or temperature, showing dynamic behaviors such as “breathing effects.” Thanks to their diversity, tunability, and functionalization, MOFs have become a core topic in porous materials research and provide a solid scientific foundation for studying adsorption performance and characterization methods.

MOFs Characterization

The fundamental characterization of MOFs typically includes powder X-ray diffraction (PXRD) patterns to determine crystallinity and phase purity, and nitrogen (N₂) adsorption/desorption isotherms to validate the pore structure and calculate apparent surface area.

Other commonly used complementary techniques include:

• Thermogravimetric Analysis (TGA): Evaluates thermal stability and can estimate pore volume in some cases.

• Water Stability Tests: Assesses structural stability in water and across different pH conditions.

• Scanning Electron Microscopy (SEM): Measures crystal size and morphology, and can be combined with energy-dispersive X-ray spectroscopy (EDS) for elemental composition and distribution.

• Nuclear Magnetic Resonance (NMR) Spectroscopy: Analyzes overall sample purity and can quantify ligand ratios in mixed-ligand MOFs.

• Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES): Determines sample purity and elemental ratios.

• Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS): Confirms the presence or absence of IR-active functional groups in the framework.

• Single-Crystal X-ray Diffraction (SCXRD): Provides precise structural information.

Below is a brief overview of sample preparation and key data analysis points for each characterization method.

1. Powder X-ray Diffraction (PXRD)

PXRD determines the crystal structure and phase purity. Experimental diffraction patterns are compared with simulated patterns from single-crystal XRD data to confirm phase purity. Samples are typically measured as powders pressed into pellets or loaded into capillaries, with rotation applied during measurement to avoid preferred orientation effects. Peak broadening usually indicates small crystallite size rather than poor crystallinity.

2. Nitrogen Adsorption/Desorption Isotherms

N₂ adsorption/desorption isotherms, measured at 77 K, are used to confirm pore structure, calculate surface area and pore volume, and evaluate pore size distribution. To ensure reliable measurements, samples must be fully activated to remove solvents, and sample mass is critical — the product of sample mass (g) and specific surface area (m²/g) should typically exceed 100 m².

Surface area is calculated using the BET model. Accurate BET results depend on proper selection of the linear region of the isotherm following Rouquerol criteria. Incorrect selection can lead to several-fold deviations in surface area (Figure 2, Table 1). CIQTEK Climber series instruments feature automated BET point selection, eliminating human error and providing reliable results even for MOFs.

Figure 2. (a) Rouquerol plot indicating correct data points (left of dashed line); (b) N₂ adsorption/desorption isotherms showing intervals used for BET plots c (green) and d (pink); (c, d) BET plots with p/p₀ ranges 0.17–0.27 and 0.004–0.05, respectively. Solid lines correspond to n(m) at p/p₀ (Rouquerol criterion iii), dashed lines correspond to 1/√C + 1 (criterion iv).

Table 1. BET areas, slopes, intercepts, C constants, monolayer capacities n(m), R², 1/√C + 1, and corresponding p/p₀ values for plots c and d in Figure 2.

3. Thermogravimetric Analysis (TGA)

TGA evaluates thermal stability and can roughly estimate pore volume based on solvent loss. The decomposition behavior depends strongly on the carrier gas (N₂, air, O₂), which should be noted in reports. Combining TGA with variable-temperature PXRD or adsorption experiments can verify structural stability after thermal treatment.

4. Scanning Electron Microscopy (SEM)

SEM observes crystal morphology and size, and can be combined with EDS for elemental analysis. Since MOFs are often insulating, charging artifacts can occur, usually mitigated by coating with a conductive layer (e.g., Au or Os). Accelerating voltage affects resolution and surface details: higher voltages yield clearer crystal outlines but may damage surface features. For EDS quantification, coating elements should be considered to avoid overlapping signals with target metals.

Figure 3. SEM images of PCN-222(Fe): with Os coating (a, c) and without coating (b, d), at 2 kV (a, b) and 15 kV (c, d). Scale bar: 5 μm.

5. Other Complementary Techniques

• ICP-OES/MS: Quantifies metal ratios and detects impurities or leaching; samples must be fully dissolved via acid digestion.

• NMR Spectroscopy: Dissolution NMR measures ligand ratios, residual modulators, and solvent removal; solid-state NMR probes ligand environments and molecular interactions.

• DRIFTS: Confirms characteristic functional groups in the framework and studies adsorption under gas flow or variable temperatures.

Combining multiple characterization methods provides a comprehensive view of MOFs’ structure, porosity, and composition, offering reliable support for performance analysis and mechanistic studies.

As hybrid fiber-coaxial (HFC) networks evolve toward higher bandwidth and faster data rates, components that support extended frequency ranges are becoming increasingly important. The move from 1.2 GHz to 1.8 GHz spectrum marks a significant upgrade in broadband infrastructure, enabling operators to deliver more capacity without a full system overhaul.
One key component in this transition is the CATV diplex filter, which separates upstream and downstream signals within a shared transmission path.

 

Why the Diplex Filter Matters

In cable and broadband systems, both forward (downstream) and return (upstream) signals travel through the same network but occupy different frequency ranges.
To prevent interference, a diplex filter acts as a frequency divider — it passes one range while blocking the other. This ensures that each direction of communication remains isolated, maintaining signal clarity and network stability.

As the industry expands toward 1.8 GHz, traditional filters are no longer sufficient. Wider bandwidth demands improved isolation, lower insertion loss, and greater mechanical precision to ensure compatibility with upgraded amplifiers and optical nodes.

 

Design Considerations for 1.8 GHz Networks

When designing or upgrading CATV systems for 1.8 GHz operation, engineers typically look at three key aspects:

1. Crossover Frequency (Split Point)
   Depending on the system architecture, different frequency splits are used — such as 5–85 MHz https://www.sanlandtech.com 102–1794 MHz, or 5–204 MHz https://www.sanlandtech.com 258–1794 MHz. Each combination serves different upstream bandwidth requirements.

2. Isolation & Insertion Loss
   The filter must maintain high isolation between return and forward paths while keeping insertion loss minimal. Poor performance in either metric can lead to distortion, cross-talk, or reduced network efficiency.

3. Mechanical and Environmental Factors
   Compact “plug-in” designs simplify maintenance and integration in dense network environments. At the same time, RoHS compliance and robust mechanical structure ensure long-term stability in the field.

   A Practical Example: 1.8 GHz CATV Diplex Filters

   A good example of such design evolution can be seen in the 1.8 GHz CATV Diplex Filter series by Sanland.
   This series includes several band-split options (e.g., 5–85 MHz https://www.sanlandtech.com 102–1794 MHz, 5–204 MHz https://www.sanlandtech.com 258–1794 MHz, 5–396 MHz https://www.sanlandtech.com 492–1794 MHz) to support diverse network plans.
   Each model is optimized for low insertion loss, high isolation, 75 Ω impedance, and a slim plug-in structure suitable for compact modules and headend applications.

    

   Future Outlook

   As operators continue extending HFC bandwidth toward 1.8 GHz and beyond, diplex filters will remain essential in ensuring reliable upstream and downstream coexistence.
   Developments in filter topology, materials, and precision manufacturing will further enhance performance and enable smooth migration to next-generation networks.
