摘要

Hydrogen evolution reaction (HER) facilitated by electrocatalytic water splitting is crucial in generation of green and clean hydrogen. The present research reports the synthesis of graphitic carbon nitride and strontium zirconate (SrZrO3/gCN) composite by a straightforward hydrothermal process. The characterizations encompass various physical and electrochemical studies to evaluate efficacy of the developed material in context of HER. The SrZrO3/gCN composite demonstrates a -131mV value of overpotential (-10 mA/cm2), which is notably lower than − 201 mV observed for pure SrZrO3 nanoparticles. It exhibited a considerable electrochemical active surface area (ECSA) value of 562.5 cm², in contrast to pure SrZrO3’s 282.5 cm². Consequently, SrZrO3 decorated sheet-like gCN demonstrates the potential for HER in a basic KOH electrolyte. The current study presents a new way of investigating a highly efficient composite electrocatalyst that integrates transition metals with carbon materials to enhance HER performance.
