What Are the Methods to Characterize Porous Structures?
Several techniques are used to characterize the pore structure of catalysts: - Nitrogen Adsorption-Desorption Isotherms: This method measures the amount of nitrogen gas adsorbed onto a material to determine its surface area and pore size distribution. - X-ray Diffraction (XRD): Used to determine the crystalline structure of materials like zeolites and MOFs. - Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM): Provide images of the pore structure and morphology. - Gas Chromatography: Often used to study the diffusion properties within the pores.
