Design strategies of perovskite nanofibers electrocatalysts for water splitting: A mini review

Electrochemical water splitting is limited by the slow reaction kinetics and large overpotential of anodic oxygen evolution reaction (OER) and cathodic hydrogen evolution reaction (HER). In this review, for the first time, we systematically summarize the design strategies for perovskite nanofiber electrocatalyst engineering. We present new insights for establishing rational OER/HER mechanism and future directions for developing next-generation perovskite nanofiber catalysts.
