Overall water splitting (OWS) for hydrogen production has attracted considerable interest as a promising route to generate green hydrogen and reduce dependence on conventional fossil fuels. However, the electrolysis efficiency of OWS is limited by the sluggish kinetics of the anodic oxygen evolution reaction (OER), a demanding four-electron transfer process, hindering large-scale implementation. This review first introduces the mechanism of water electrolysis, the various components of water electrolyzers, and optimization strategies under high-current-density conditions. Subsequently, it focuses on optimization strategies for working electrodes, elucidates the reaction mechanisms of various alternative anodic oxidation reactions (including urea, hydrazine, 5-hydroxymethylfurfural, alcohols, and aldehydes, among others), explores novel high-current-density hydrogen production systems coupled with water electrolysis, and examines the impact of external factors on electrolyzer operation-all aimed at achieving enhanced hydrogen production efficiency. Finally, the challenges, application prospects, and potential of these advanced electrolysis systems are emphasized, aiming to provide novel and efficient approaches for advancing the development of green hydrogen energy. This review aims to provide systematic guidance for advancing water electrolysis technology, facilitating the industrialization of efficient hydrogen production.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Reduction of Alkenes: Catalytic Hydrogenation
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.
