Abstract

The construction of highly active and durable non-noble-metal electrocatalysts for the oxygen evolution reaction (OER) is an ongoing challenge. Here, we report the development of a hybrid nanostructure of PBA cubes wrapped with mixed W-Co oxysulfides in a hair-like structure through sulfurization of polyoxometalate (Co^IIIW₁₂ POM) as a bimetallic precursor. These unique heterostructures of PBA@Co−W−O−S grafted on carbon cloth afford abundant active sites and improved charge transfer kinetics that synergistically enhance the OER activity (overpotential of 250 mV at 10 mA cm⁻²). The synthetic approach used in this report can be extended for developing inexpensive, durable and efficient catalysts with diverse structures.
