Abstract:
Herein, a universal approach is proposed to prepare a nitrogen-doped mesoporous Ru film with uniform pore size on nickel foam (N-mRu/NF) as an active bifunctional catalyst for energy-saving hydrogen production. The N-mRu/NF requires an ultrasmall overpotential of -60 and 62 mV to achieve 100 mA cm-2 for the hydrogen evolution reaction (HER) and hydrazine oxidation reaction (HzOR), respectively. When used for HER-HzOR electrolysis, N-mRu/NF requires low voltages of 0.023 and 0.184 V at 10 and 100 mA cm-2, respectively.

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.
