Abstract
Developing effective and earth-abundant electrocatalyst for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is critical for the commercialization of a water splitting system. In particular, the overpotential of the OER is relatively higher than the HER, and thus, it is considered that one of the important methods to enhance the performance of the electrocatalyst is to reduce the overpotential of the OER. In this work, we present a simple synthetic route for triple perovskite Nd1.5Ba1.5CoFeMnOx with high performance OER and HER activity. This triple perovskite structure which shows high crystallinity through combustion method shows superior bifunctional catalytic performance in alkaline media. We believe that the prepared triple provskite with high performance OER and HER activity can give further feasibility for the commercialization of a water splitting system.
