Abstract

A degradation of organic dyes catalyst with stable structure and efficient performance, SiO₂ coated Co₃O₄ and Ag nanocapsules have been successfully prepared by the simple in-situ method and template method, which shown excellent catalytic performance for degrade methyl orange dye in solution. The degradation rate constant (k) of Co₃O₄@SiO₂-Ag was 0.150 min⁻¹. The combination of two metals and the hollow mesoporous structure significantly improved the catalytic performance of the material.
