Hydrothermal synthesis of highly dispersed Bi–Ni–Sb–O pyrochlore for catalytic oxidation of carbon monoxide

Abstract

The highly dispersed Bi–Ni–Sb–O pyrochlore was prepared under hydrothermal conditions with and without microwave treatment. Composite samples of NiO/(Bi–Ni–Sb–O pyrochlore) demonstrated consistently high activity without pretreatment in CO oxidation
