“…Electro-oxidation of organics is an attractive alternative to the OER. Chen et al summarized the latest progress on coupled H 2 production with organic electro-oxidation systems. Different organic compounds containing oxygen, nitrogen, sulfides, and olefin/alkane groups have been selectively oxidized into high-value-added products on the anodes, thereby promoting H 2 evolution on the cathodes.…”

“…Developing clean energy technologies to meet the ever-increasing energy demands and to minimize the environmental impacts of energy use is one of the most crucial challenges. − As a green and sustainable energy carrier, hydrogen could be obtained from water splitting by various renewable electric energy sources such as wind, solar, etc. − For water splitting, the anode ended with oxygen evolution reaction (OER) presents a high energy barrier, which greatly limits the total energy efficiency for hydrogen production on the other end. − Studies have focused on the designing of highly active and economical OER catalysts to replace the traditionally precious IrO 2 and RuO 2 catalysts and to improve hydrogen production efficiency. − …”

Integration of hydrogen evolution with the oxidation of organic substances in one electrochemical system is highly desirable. However, achieving selective oxidation of organic substances in the integrated system is still highly challenging. In this study, a phosphorylated NiMoO 4 nanoneedle-like array was designed as the catalytic active electrode for the integration of highly selective electrochemical dehydrogenation of tetrahydroisoquinolines (THIQs) with hydrogen production. The leaching of anions, including MoO 4 2− and PO 4 3− , facilitates the reconstruction of the catalyst. As a result, nickel oxyhydroxides with the doping of PO 4 3− and richness of defects are in situ formed. In situ Raman and density functional theory calculations have shown that the high catalytic activity is attributed to the in situ formed PO 43− involved NiOOH substance. In the dehydrogenation process, the involved C−H bond but not the N−H bond is first destroyed. A two-electrode system was then fabricated with the optimized electrode that shows a benchmark current density of 10 mA cm −2 at 1.783 V, providing a yield of 70% for dihydroisoquinolines. A robust stability was also shown for this integrated electrochemical system. The understanding of the reconstruction behavior and the achievement of selective dehydrogenation will provide some hints for electrochemical synthesis.
