Abstract:
Cyano- and urea-defective group co-modified nitrogen-deficient carbon nitride with PtSn as a cocatalyst was constructed to optimize the optical and electronic structure as well as the photocatalytic activity. Defective engineering over carbon nitride gave rise to a stronger light absorption in the visible and near-infrared regions, more negative conduction band edge potential and more efficient separation behavior of photogenerated charge carriers. The optimal photocatalyst exhibited a high hydrogen yield of 2.96 mmol g-1 h-1 with an apparent quantum yield of 8.42% at 435 nm. Moreover, the photocatalytic hydrogen generation capability was maintained under illumination up to 765 nm with an apparent quantum yield of 0.076%.

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.
