Abstract

Bismuth tungstate anchored PEDOT: PSS (BiW@PEPS) electrocatalyst was prepared via hydrothermal and ultrasonication methods successively. The synergetic effects of bismuth tungstate with PEDOT: PSS conducting polymer showed excellent electrocatalytic performance of hydrogen evolution reactions (HER) in alkaline conditions. When compared with pristine bismuth tungstate, the BiW@PEPS exhibited an enhanced electrocatalytic activity with a lower overpotential of 361 mV at 10 mA cm⁻², small Tafel slope of 106 mV/dec and enduring stability in 1 M KOH electrolyte. The enhanced electrocatalytic performance of the BiW@PEPS proved to be a beneficial electrocatalyst to the high-cost platinum-based materials in hydrogen production applications.
