Abstract
A Fenton-like catalyst material with an electron-poor Cu center and a preparation method and use thereof are provided. The preparation method includes: step 1: dissolving bismuth nitrate pentahydrate in a nitric acid solution and diluting a resulting solution with deionized water to obtain a solution A; step 2: adding citric acid to the solution A and adjusting a pH of a resulting solution with ammonia water to obtain a solution B; step 3: dissolving aluminium isopropoxide (AIP), copper chloride dihydrate, and glucose in the solution B to obtain a suspension C; step 4: stirring the suspension C at a high temperature to allow evaporation until a solid D is completely precipitated; and step 5: subjecting the solid D to calcination in a muffle furnace to obtain the Fenton-like catalyst material. Under neutral conditions, the catalyst material exhibits a prominent removal effect for various toxic organic pollutants, especially for phenolic pollutants.
