Abstract:
CdxZn1-xSe/CoP composites have been well studied as effervescent photocatalysts for H2 evolution. These composites are highly efficient at 45.1 mmol h-1 g-1 and have a high quantum yield of 11.8% at ∼520 nm. The tunable energy band of CdxZn1-xSe facilitates photo-electrons transferring to CoP via chemical bonds between components. Advances in CdxZn1-xSe/CoP for photocatalytic H2 evolution provide a new strategy for future splitting of seawater.

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...

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.
