A facile synthesis for porous CuO/Cu2O composites derived from MOFs and their superior catalytic performance for CO oxidation

Abstract Toxic gas CO has attracted great attention due to their strong impact on human health. Here, CO reaction in CO oxidation was used to treatment catalyst and add a new application. Satisfactorily, highly uniform and well dispersed octahedral CuO/Cu 2 O composite derived from CuBTC is successfully synthesized, which still retain the original morphology of the MOFs. Moreover, CuO/Cu 2 O composite showed an excellent catalytic performance, which was ascribed to the higher Cu 2 O/CuO ratio, good low temperature reduction behavior and a high quantity of surface active oxygen species. Importantly, this simple method reported in this work can be universal and facilely expand to other metal oxides, synthesizing diverse MOFs based metal oxides.
