Synthesis of Nanoporous Ni-Co Mixed Oxides by Thermal Decomposition of Metal-Cyanide Coordination Polymers

Abstract

A straightforward strategy to prepare nanoporous metal oxides with well-defined shapes is highly desirable. Through thermal treatment and a proper selection of metal-cyanide coordination polymers, nanoporous nickel-cobalt mixed oxides with different shapes (i.e., flakes and cubes) can be easily prepared. Our nanoporous materials demonstrate high electrocatalytic activity for oxygen evolution reaction.
