Transition metal oxide based oxygen reduction reaction electrocatalysts for energy conversion systems with aqueous electrolyte

Abstract

In the past decades, there has been a strong incentive to develop electric vehicles by the introduction of batteries to reduce the dependence on petroleum oil and mitigate the tailpipe emissions. The lithium-ion batteries have dominated the electric vehicles market due to their high capacity and energy efficiency. But the insufficient energy density of lithium-ion batteries is still a big problem for the development of electric vehicles. Metal-air battery has been considered as one of the most promising power sources for electric vehicles due to some attractive advantages, such as the high energy density, low cost and environment-friendliness. One of the most important issues for metal-air batteries is developing the oxygen reduction reaction catalysts with high catalytic activity and stability. Transition metal oxides are a series of important catalyst for oxygen reduction reaction in alkaline solution. The purpose of this paper is to provide a comprehensive review on recent progress in transition metal oxides-type catalyst for ORR in aqueous media, including simple transition metal oxides-type catalysts, perovskite-type catalysts, spinel-type catalysts, and other ternary transition metal oxides catalysts (such as double perovskite oxides, pyrochlore oxides, Ruddlesden-Popper oxides, LiCoO2-related oxides, and Mn-based mullite oxides). Moreover, we also discuss the influence factors of the transition metal oxides-type catalysts for ORR in metal-air batteries with aqueous electrolyte.
