Abstract:
Hydrogen energy has garnered significant attention in recent years as a solution to address the global energy crisis and environmental pollution. While water electrolysis stands out as the most promising method to produce green hydrogen, the sluggish reaction kinetics of the oxygen evolution reaction (OER) on the anode increases the cost of hydrogen production. One potential solution to this challenge is replace OER with the thermodynamically more favorable oxidation of small molecules, which can efficiently reduce the energy cost while simultaneously yielding high-value chemicals. Up to now, various organic oxidation reactions have been reported to couple with hydrogen evolution, including alcohol oxidation, biomass platform molecule upgrading, and sacrificial reagents oxidation associated with wastewater treatments. This review concentrates on the recent advancements in the mechanism, catalyst, reactor, and process in this field, with a discussion on its prospects for commercialization.

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.

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...

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
