▎ 摘　　要

NOVELTY - Preparing high dispersion metal or metal oxide doped adsorbent comprises using porous metal oxide or two-dimensional material as carrier, loading metal organic polyhedron, preparing high dispersion metal or metal oxide doped adsorbent by reduction or oxidation reaction, where the metal or metal oxide comprising palladium, rhodium, copper, zirconium or zinc, and the content of metal or metal oxide is 0.1-6 mmol/g. USE - The method is useful for preparing high dispersion metal or metal oxide doped adsorbent. ADVANTAGE - The method: is simple; can limit the metal node number in the metal organic polyhedron; improves the dispersion degree of the metal or metal oxide; enhances the complexing ability of the active site; and improves the adsorption separation performance.
