Production Of Hydrogen

AbstractAs a promising substitute for fossil fuels, hydrogen has emerged as a clean and renewable energy. A key challenge is the efficient production of hydrogen to meet the commercial-scale demand of hydrogen. Water splitting electrolysis is a promising pathway to achieve the efficient hydrogen production in terms of energy conversion and storage in which catalysis or electrocatalysis plays a critical role. The development of active, stable, and low-cost catalysts or electrocatalysts is an essential prerequisite for achieving the desired electrocatalytic hydrogen production from water splitting for practical use, which constitutes the central focus of this review. It will start with an introduction of the water splitting performance evaluation of various electrocatalysts in terms of activity, stability, and efficiency. This will be followed by outlining current knowledge on the two half-cell reactions, hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), in terms of reaction mechanisms in alkaline and acidic media. Recent advances in the design and preparation of nanostructured noble-metal and non-noble metal-based electrocatalysts will be discussed. New strategies and insights in exploring the synergistic structure, morphology, composition, and active sites of the nanostructured electrocatalysts for increasing the electrocatalytic activity and stability in HER and OER will be highlighted. Finally, future challenges and perspectives in the design of active and robust electrocatalysts for HER and OER towards efficient production of hydrogen from water splitting electrolysis will also be outlined.

Chalcogenide Thin Film

Photoelectrochemical (PEC) water splitting holds a great promise for clean and sustainable hydrogen production. In this study, the PEC performance of Co–Mo–Se ternary chalcogenide thin film coated Si photocathodes is investigated. The Co–Mo–Se films with various Co/Mo atomic ratios were prepared by thermal selenization of sputter deposited Co–Mo alloy films. Among the photocathodes, the Co–Mo–Se (3:10)/[Formula: see text]-Si surpasses the PEC performance of the MoSe2/[Formula: see text]-Si with an onset potential of +124 mV vs. reversible hydrogen electrode (RHE), a photocurrent density of −22.68 mA/cm2 at zero overpotential and good stability over 6 h period of test. The superior performance of the Co–Mo–Se (3:10)/[Formula: see text]-Si is ascribed to the high catalytic activity of the film in hydrogen evolution reaction (HER) and efficient collection of photogenerated charge carriers. Such ternary chalcogenide thin films offer exciting opportunities for many applications in which the physicochemical properties can be tuned by changing the relative amount of the solute atoms.
