Abstract:
Hydrogen is expected to be crucial in decarbonized economies as a low-carbon energy carrier and feedstock. Currently, hydrogen generation relies on fossil fuels, causing environmental issues. Green hydrogen, produced through water electrolysis, offers a feasible alternative with low greenhouse gas emissions. Geographical islands have potential as hydrogen export centers due to their high-capacity factors and low population densities. Large-scale hydrogen production can boost regional economic development. This presentation explores a new form of inorganic semiconductor-based nanostructures (ISNSs) prepared using laser irradiation techniques for hydrogen production via water electrolysis. The ISNSs-based working electrode demonstrates good electrochemical performance, including low over-potential, Tafel slope, double-layer capacitance, large electrochemically active surface area, and extraordinary long-term stability. The improved hydrogen production efficiency was attributed to the strong metal-support interaction, high conductivity, high active site exposure, large active surface area, enhanced kinetics, and rapid charge transport. The ISNSs-based electrode also outperformed in electrocatalytic hydrogen production activity and stability. This systematic method of developing ISNSs-based electrodes for hydrogen production could help generate green energy, alleviate future environmental concerns, and avert energy crises.
