| description | As the world moves toward a hydrogen economy and environmental sustainability, an
effective and cost-effective electrocatalyst for hydrogen evolution reaction (HER) in
electrochemical water splitting becomes increasingly important.
We researched and synthesised an optimum metal phosphate with model stoichiometric
ratio of Cobalt (Co) and Molybdenum (Mo) components to improve HER performance in this
paper. To introduce Mo dopant to our cobalt phosphate (Co2P) synthesis, the ratio of Mo in our
synthesis is as follows [Co2P+Mox% ] is varied where x = 5%, 10%, 15%, 20% and 25% . We
used X-ray Diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), X-ray
Spectroscopy (XPS), Linear Sweep Voltammetry (LSV), Tafel plot measurements, and durability
tests to evaluate the efficacy of Mo doped Co2P as electrocatalyst for HER performance.
Based on our findings, Co2P+Mo10% doped is the optimal HER catalyst in terms of its
HER activity and durability. Surface changes of Co atoms caused by Mo doping result in Co's
presence as a dominating phase, resulting in strong HER activity. This finding suggests that more
research is needed to develop a non-noble catalyst for HER |
