Abstract:
Catching the sunlight: The disordered Co1.28Mn1.71O4 was synthesized by a facile reduction method in the presence of amorphous MnO2 precursors and Co(2+). It exhibits relatively high hydrogen-production activity under visible-light irradiation (see figure). The larger number of active sites in the bulk catalyst endow nanoparticles with improved water-reduction activity. This is the first demonstration of disordered ternary oxides for visible-light-driven hydrogen evolution in the absence of a cocatalyst.

Heterogeneous Catalysis
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.
The hydrogenation process takes place on the surface of...

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...
