| Summary: | <p dir="ltr">The design of a catalyst plays a significant role in developing high-performance renewable energy materials. Among these, the catalyst engineering for the electrochemical <u>oxidation</u> of fuels at the anode of the fuel cells has drawn focus due to their broad impact on modern research. To this end, major challenges have been considered, including enhanced performance, a durable nature, and the low economic cost of the<u> electrocatalyst</u> material. Handling the mentioned goals, cubic-shaped copper (I) <u>oxide</u> (Cu<sub>2</sub>O) as catalyst support for the fabrication of low-content PtIr <u>binary alloys</u> has been used to synthesize a catalyst. Among the brief library of the synthesized catalysts series, Pt2Ir1/Cu<sub>2</sub>O NC has exhibited enhanced oxidation of methanol in a half-cell testing system with high <u>current density</u> (1443 mA/mgPt) and low onset <u>oxidation potential</u> (∼0.45 V vs RHE), thus outperforming commercial Pt/C and PtRu/C<u> electrocatalysts</u>. Additionally, this electrocatalyst exhibited a superior performance in ethanol oxidation reaction with high current density (2190 mA/mgPt), which also exceeded the respective value of the commercial Pt/C (657 mA/mgPt) and other catalysts investigated in this study. The exceptional performance is mainly ascribed to the structural and electronic effects joining strong metal-to-support interactions among the catalyst material, which are also successfully confirmed from materials characterizations.</p><h2 dir="ltr">Other Information</h2><p dir="ltr">Published in: International Journal of Hydrogen Energy<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.ijhydene.2025.02.394" target="_blank">https://dx.doi.org/10.1016/j.ijhydene.2025.02.394</a></p> |
