Abstract:
The necessity of efficient electrolyzers for H2 production has boosted the number of publications on the development of highly active and stable electrocatalysts. Recently, transition metal phosphides (TMPs) have been reported as excellent materials for H2 electrochemical production. Though most publications demonstrate the applicability of Co, Mo, Fe, and Ni-based TMPs in a wide pH range, there's a lack of consolidated information about the material's durability versus pH, especially in harsh environments (e.g., high acidity or alkalinity and seawater). The main purpose of this review is to correlate the advancement of knowledge about the TMPs electronic and physical-chemical properties and the improvement of hydrogen evolution reaction in a wide range of pH and salinity to present some meaningful perspectives for the near future development.

02:17Reduction 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...
02:13Reduction 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.

02:24Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
