High-efficiency electrocatalytic hydrogen generation under harsh acidic condition by commercially viable Pt nanocluster-decorated non-polar faceted GaN nanowires
Electrochemical water splitting is vital for green hydrogen production and clean energy. This study introduces a novel approach: platinum nanoclusters (Pt NCs) decorated GaN nanowires (GNWs) on p++-Si substrates to enhance hydrogen generation efficiency. Highly-crystalline GNWs synthesized via commercial metal-organic chemical vapor deposition provide a scalable platform for hydrogen evolution. To address the cost limitations of Pt-based electrocatalysts, we developed a method for loading ultralow Pt NCs via photoelectrochemical deposition. Investigations underscore the Pt–Ga sites' crucial role in promoting efficient H2 production. The Pt NCs/GNWs/p++-Si electrode achieved −10 mA/cm2 current density at +50 mV vs. the RHE and sustained −20 mA/cm2 for 90 h under harsh acidic conditions at room temperature and atmospheric pressure with nearly 100% retention. This study offers insights into efficient and stable electrodes for electrochemical H2 generation.
期刊介绍：
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
