摘要

Uranium garners enough attention, not only as a high priority contaminant but also as the major infrastructure of nuclear energy systems. This review comprehensively discusses uranium(VI) capture by zeolite-based materials. Among various factors, pore size and pH play critical roles. Morphological control, surface modification and composite formation are effective to promote uranium capture. Mesoporous SBA-15 and MCM-41 with surface modification have uranium(VI) adsorption of 804.8 and 807.3 mg/g, and show prospects for uranium extraction from seawater. The updated understanding feeds back design of zeolite-based scavengers, which hopefully resolve the burgeoning energy demand and deteriorating ecological environment towards a sustainable society.
