Title
Synthesis of hydrogen peroxide from carbon monoxide, water and oxygen catalyzed by amorphous NiP(B)/Al2O3
Abstract

Amorphous NiP(B)/Al2O3 catalysts were prepared by a coating method. The factors that influence the preparation of the catalysts, such as plating temperature, the initial pH value of the plating solution, the loadings of NiP and the temperature of heat treatment, were studied in detail. The catalysts were characterized with XRD, SEM and XPS, and were studied in the reaction for the synthesis of hydrogen peroxide from carbon monoxide, water and oxygen. The results showed that the catalysts had amorphous structure with Ni–P–B alloy formed on the surface; that the catalysts had better activity and stability than the catalysts reported previously when the H2O2 production rate reached 0.228 mmol/(g h), which is higher than the maximum rate of 0.1 mmol/(g h) over noble catalysts (5% Pd/CaCO3 and 1% Ru/graphite) and 0.07 mmol/(g h) over Ni–La–B/Al2O3 catalyst; and that the preparation conditions significantly influenced the activities of the catalysts. The higher stability values of the catalysts were attributed to the amorphous Ni–P–B structure.
