Abstract The use of light as a catalytic prompt for the synthesis industrial relevant compounds is widely explored in past years, with special consideration over hydrogen evolution reaction (HER). However, semiconductors heterogeneous photocatalysis suffer from fast charge recombination and, consequently, low solar‐to‐hydrogen efficiency. These drawbacks can be mitigated by coupling photocatalysts an external circuit that physically separate photogenerated carriers (electrons and holes). For this reason, photoelectrochemical (PEC) production under spotlight promising green sustainable technique investigated numerous publications. considering significant fraction produced used reduction processes, development PEC devices direct situ hydrogenation address challenges associated storage distribution. This Perspective aims at highlighting fundamental aspects HER systems, how these harnessed toward implementation suitable settings organic value.

Journal of the American Chemical Society, Год журнала: 2025, Номер 147(2), С. 1938 - 1947

Опубликована: Янв. 2, 2025

Green electricity-driven alkenol electrosynthesis via electrocatalytic alkynol semihydrogenation represents a sustainable route to conventional thermocatalysis. Both the electrocatalyst and electrolyte strongly impact performance. Despite significant progress in developing sophisticated electrocatalysts, well-designed conjunction with industrial catalysts is an attractive strategy advance industrialization process of semihydrogenation, but remains unexplored. Here, we develop dimethyl sulfoxide (DMSO)-H2O cosolvent for semihydrogenation. At conversion about 100%, DMSO-H2O compared DMSO-free counterpart enables selectivity on Cu be promoted from 60–70% over 90% at all measured current densities; meanwhile, reaction rate slightly decreased due inhibited water dissociation. Mechanistic studies reveal that strong hydrogen-bond interactions between DMSO H2O suppress dissociation interfacial H2O, leading H* coverage electrode surface. The hinders overhydrogenation alkynols favors production alkenols. Remarkably, DMSO-induced enhancement applicable set commercial various alkynols. Eventually, scaled-up 3 × 100 cm2 electrolyzer stack established achieve ∼96% ∼95% electrolyte. This work not only presents boosting electrosynthesis, also highlights possibility electro-production.

Abstract Molybdenum carbide (Mo 2 C), known for its platinum‐like electronic structure and excellent corrosion resistance, has demonstrated promising catalytic performance in laboratory tests. However, under industrial harsh conditions, the of Mo C faces constraints due to inherently strong hydrogen adsorption. Additionally, at elevated current densities, rapid depletion active species electrolyte, coupled with gas bubble accumulation, introduce significant mass transport challenges. This work introduces an electrode Mo‐Mo heterostructures supported on a plate (Mo‐Mo C/Mo). Further analyses reveal that incorporating metallic into optimizes C. optimization achieves more balanced adsorption, while also enhancing capacity water adsorption dissociation C, collectively improving activity. Furthermore, this features unique “bush‐like” surface morphology can induce “turbulence” effect electrolyte near surface, facilitating flow transport. As result, C/Mo exhibits high densities (η 1000 = 452 mV). Moreover, resistance robust integration ensure long‐term stability, remaining stable 1.5 A 6 M KOH over extended periods.
