Prominently progressive development of Ni-based oxygen-evolving electrocatalysts for water splitting
【Abstract】
Sustanable carbon-neutral sociey in future requres to develop efficient chemical conversion systems from solar light energy to CO2-free fuels such as H2 alternative to fossil ones. Water splitting driven by solar energy is one of the most promising approaches for sustinable H2 production. The critical bottleneck to establish efficient water splitting systems has remained in sluggish oxygen evolution reactions (OER) with insufficiently low overpotentials (ηO2). Development of highly efficient OER electrocatalysts to minimize ηO2 is a challenging key task to attain efficient water splitting. Recently, there has been prominent progress on development of efficient Ni-based electrocatalysts providing extremely low ηO2. Herein, the aspects and mechanisms for state-of-the-art Ni-based OER electrocatalysts reported in recent three-year from 2020 to 2023 were reviewed. We will discuss perspectives to develop efficient Ni-based OER electrocatalysts based on comprehensive understanding of catalysts introduced in this review.
