Geopolymer catalysts demonstrate significant potential in green catalysis through the synergistic interplay between their porous framework and tunable active sites.This review focused on the synergistic design strategy of “porous framework-active site” and systematically elaborated on various active center construction pathways based on geopolymer materials,including direct utilization,in-situ transformation,blending modification,liquid-phase loading,and synergistic compositing,thereby achieving precise regulation and stable anchoring of catalytic active sites.Their applications in pollutant degradation,CO2 conversion,biomass valorization,and chemical catalysis were discussed,revealing key mechanisms such as adsorption-catalysis synergy,enhanced mass transfer via porous structures,and strong interactions between active components and the carriers.Sourced from solid waste,these catalysts offered advantages of low cost,tunable structure,and excellent recyclability,providing crucial technical support for the advancement of green and low-carbon catalytic systems.
