A bifunctional electrocatalyst based on interfacial engineering of CeO₂ and NiSe₂ for boosting electrocatalytic water splitting

Abstract

A novel bifunctional electrocatalyst with a 3D structural CeO2–NiSe2 in situ grown on nickel foam is reported. It shows remarkable activities for the OER and the HER as well as superior electrocatalyst performance in overall water splitting.

Constructing a medium-entropy spinel oxide FeNiMnO4/CeO2 heterojunction as a high-performance electrocatalyst for the oxygen evolution reaction

“…Mushrooming energy demand, coupled with concerns over fossil fuel depletion and greenhouse gas emissions, has spurred the exploration of clean energy technologies for efficient conversion and storage. 1,2 Among the novel clean energy technologies, rechargeable metal–air batteries 3–5 and water electrolysis, 6–8 which involve the oxygen evolution reaction (OER), have attracted an amount of attention because of their superior simplicity, reliability and non-polluting properties. 9–13 However, the slow kinetics and high overpotential greatly confine the OER, leading to considerable loss of energy during the reaction.…”
