Mikroporiset
Mikroporiset (microporous materials) are solids containing a substantial fraction of pores smaller than 2 nanometers. The presence of sub-nanometer to nanometer pores leads to high internal surface areas and strong size- and shape-selective adsorption. Microporosity is defined in contrast with mesoporosity (2–50 nm) and macroporosity (greater than 50 nm).
Common examples include zeolites, activated carbons, and certain metal-organic frameworks and covalent organic frameworks that feature
Synthesis often involves hydrothermal or solvothermal methods, templating approaches, or activation steps. Characterization relies on gas
Applications span gas storage and separation (such as CO2 capture and H2 storage), catalysis (zeolites and MOF-based
