Coffee Ground-Derived Carbon Molecular Sieves: Controllable Microdomain Structure Evolution for Sub-Angstrom Molecular Sieving of C4 Olefin Mixture

ternary mixture. Additionally, the structure-performance relationship of these amorphous CFGCMS materials is clarified. This study demonstrates that biomass can be transformed into advanced CMS with subangstrom molecular recognition precision, comparable to crystalline MOF materials, thereby providing valuable guidance for the development of novel carbon molecular sieves from diverse biomass-derived carbon sources for gas separation applications.
