Abstract:
Electrocatalytic hydrogen evolution coupled with ethylene glycol oxidation (EGOR) offers a promising approach for sustainable hydrogen production. However, conventional systems suffer from high energy demands and limited stability under industrial current densities. In this study, a nitrogen vacancy-engineered Ni/Mo dual metal atom catalyst (NiMo-BN-Pe) is developed. This design achieves exceptional alkaline Hydrogen Evolution Reaction activity with an ultralow overpotential of 37.1 mV at 10 mA cm-2 and maintains high stability, outperforming many previously reported materials. Moreover, coupling HER with the ethylene glycol oxidation reaction (EGOR) enables the concurrent production of high-value chemicals. Density functional theory (DFT) calculations reveal the role of nitrogen vacancies as catalytic hotspots in stabilizing critical reaction intermediates through proton-coupled electron transfer. This work provides a versatile platform for coupling HER with anodic biomass oxidation reactions.

02:36Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn stereochemistry.

Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

02:15Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
