- Abstract
- The development of bifunctional electrocatalysts for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) has recently attracted significant attention. Transition metal-based electrocatalysts have demonstrated a highly promising catalytic performance in electrochemical HER or OER. Moreover, their electrocatalytic performance can be further improved using a self-supported structure of the electrocatalyst, owing to strong physicochemical contact between the catalyst and current collector. In this context, we propose vanadium-incorporated cobalt phosphide (CoVP) self-supported catalysts on carbon cloth (CoVP@CC) as highly efficient bifunctional electrocatalysts for alkaline HER and OER. In CoVP@CC, V plays a crucial role in modulating the surface electronic structure of the self-supported CoP nanosheets, leading to excellent catalytic activity in both HER and OER. The self-supported CoVP@CC demonstrates a promising overall water-splitting performance, requiring only 1.61 V to afford a current density of 10 mA cm(-2).
