The catalyst has a macroporous structure, which is composed of nanoballs with a high purity, crystallinity, and uniform morphology. The electrocatalyst is excellent for MOR, as it delivers a current density of 37.28 mA/mg at a potential of 0.6 V (vs Ag/AgCl) in the electrolyte of 1 M KOH and 0.75 M methanol at a 50 mV/s scan rate under conditions of cyclic voltammetry. The catalyst also shows good stability for 3600 s with negligible charge transfer resistance and a high electrochemical active surface area (ECSA) value of 0.100 mF/cm². <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MOR" title="MOR">MOR</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20selenide" title=" copper selenide"> copper selenide</a>, <a href="https://publications.waset.org/abstracts/search?q=electocatalyst" title=" electocatalyst"> electocatalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20application" title=" energy application"> energy application</a> </p> <a href="https://publications.waset.org/abstracts/178089/formation-mechanism-of-macroporous-cucuse-and-its-application-as-electrocatalyst-for-methanol-oxidation-reaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178089.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Advanced Study on Hydrogen Evolution Reaction based on Nickel sulfide Catalyst</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kishor%20Kumar%20Sadasivuni">Kishor Kumar Sadasivuni</a>, <a href="https://publications.waset.org/abstracts/search?q=Mizaj%20Shabil%20Sha"> Mizaj Shabil Sha</a>, <a href="https://publications.waset.org/abstracts/search?q=Assim%20Alajali"> Assim Alajali</a>, <a href="https://publications.waset.org/abstracts/search?q=Godlaveeti%20Sreenivasa%20Kumar"> Godlaveeti Sreenivasa Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Aboubakr%20M.%20Abdullah"> Aboubakr M.

Hydrogen generated by electrocatalytic water splitting requires active, stable, and low-cost catalysts or electrocatalysts to be developed for practical applications. In this study, we evaluated combination of 2D materials of NiS nanoparticle catalysts for hydrogen evolution reactions. The photocatalytic H₂ production rate of this nanoparticle is high and exceeds that obtained on components alone. Nanoparticles serve as electron collectors and transporters, which explains this improvement. Moreover, a current density was recorded at reduced working potential by 0.393 mA. Calculations based on density functional theory indicate that the nanoparticle's hydrogen evolution reaction catalytic activity is caused by strong interaction between its components at the interface. The samples were analyzed by XPS and morphologically by FESEM for the best outcome, depending on their structural shapes. Use XPS and morphologically by FESEM for the best results. This nanocomposite demonstrated higher electro-catalytic activity, and a low tafel slope of 60 mV/dec. Additionally, despite 1000 cycles into a durability test, the electrocatalyst still displays excellent stability with minimal current loss. The produced catalyst has shown considerable potential for use in the evolution of hydrogen due to its robust synthesis. According to these findings, the combination of 2D materials of nickel sulfide sample functions as good electocatalyst for H₂ evolution. Additionally, the research being done in this fascinating field will surely push nickel sulfide-based technology closer to becoming an industrial reality and revolutionize existing energy issues in a sustainable and clean manner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20hydrogenation" title="electrochemical
