Nanoporous structured mixed transition metal oxides nanomaterials for electrochemical energy conversion technologies

Abstract

Abstract Emergent nanomaterials of porous-structured mixed transition metal oxides have demonstrated to be promising nanomaterials for various electrochemical energy conversion reactions, including oxygen reduction reaction (ORR), hydrazine oxidation reaction (HOR), glucose oxidation reaction (GOR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER), etc. In this featured letter, I intend to present the synthesis, properties, electrode fabrication methodologies, and the applications in electrochemical energy conversion technological performance of the nanoporous-structured nickel–cobalt oxide (NP-NCO) nanomaterials mainly based on our very recent research. The present challenges, and future outlook of the NP-NCO in electrochemical energy conversion reactions are also described on the basis of present attainment.
