| الملخص: | <p dir="ltr">Electrochemical water splitting is a promising pathway for effective hydrogen (H<sub>2</sub>) evolution in energy conversion and storage, with electrocatalysis playing a key role. Developing efficient, cost-effective and stable catalysts or electrocatalysts is critical for hydrogen evolution from water splitting. Herein, we evaluated a graphene-modified nanoparticle catalyst for hydrogen evolution reaction (HER). The electrocatalytic H<sub>2</sub> production rate of reduced graphene oxide-titanium oxide-nickel oxide-zinc oxide (rGO–TiO<sub>2</sub>–NiO–ZnO) is high and exceeds that obtained on components alone. This improvement is due to the presence of rGO as an electron collector and transporter. Moreover, a current density of 10 mA/cm<sup>2</sup> was recorded at a reduced working potential of 365 mV for the nanocomposite. The electronic coupling effect between the nanoparticle components at the interface causes the nanoparticle's hydrogen evolution reaction catalytic activity.</p><h2>Other Information</h2><p dir="ltr">Published in: Catalysis Letters<br>License: <a href="https://creativecommons.org/licenses/by/4.0" target="_blank">https://creativecommons.org/licenses/by/4.0</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1007/s10562-023-04339-6" target="_blank">https://dx.doi.org/10.1007/s10562-023-04339-6</a></p> |
