Abstract
A method for preparing a supported catalyst, including mixing waste lithium battery cathode material and biomass uniformly to obtain a mixture, then putting the mixture into a tube furnace for nitrogen purging, and then heating and calcining to obtain a solid sample after carbothermal reduction treatment; hydrothermally stirring the solid sample, followed by filtration to recover a residue, and drying the residue to obtain a mixed sample of CoO, TiO, and biochar, labeled as TCO; ultrasonically dispersing the attapulgite in an acid solution, stirring in a water bath at 80° C. to obtain a product, washing the product until neutral, filtering, and then drying to obtain an acidified attapulgite (H-ATP); and weighing the TCO, ultrasonically dispersing the TCO in a mixed solution of deionized water and N, N dimethylformamide (DMF), adding the H-ATP into the mixed solution, and performing a microwave hydrothermal reaction, obtaining a sample after centrifuging, washing, and drying, and then performing muffle calcination on the sample to obtain the supported catalyst Co(Ti)O/H-ATP.
