A tailored polyoxometalate-derived RuW/g-C₃N₄-based electrocatalyst for enhanced hydrogen evolution reaction

Abstract

As a next-generation electrocatalytic material, Ru–W nanocluster-modified g-C3N4 was synthesized using a straightforward monomer-complexation route from Ru-substituted phosphotungstate, for efficient hydrogen evolution reaction.

Recent research progress on polyoxometalate-based electrocatalysts in energy generation

“…Another study conducted by Pathan et al involved the synthesis of highly dispersed RuW/g-C 3 N 4 composite materials. 130 This was achieved by complexing a ruthenium-substituted POM (PW 11 Ru) with melamine, followed by calcination under an inert atmosphere. The RuW/g-C 3 N 4 composite displayed improved electrochemical activity for HER, with an overpotential of approximately 266 mV at j = 10 mA cm −2 and a Tafel slope of 63 mV dec −1 .…”
