Proton exchange membrane water electrolyzers (PEMWEs) has become a promising clean energy technology. The development of highly active and stable Ru-based catalysts with high oxygen evolution reaction (OER) activity is crucial to the practical application of PEMWE because of the rare and high cost Ir. Moreover, the high performance OER catalyst could be used in anode to improve the anti-reversal performance for proton exchange membrane fuel cell (PEMFC). In this work, the RuMnSnOxcatalyst exhibits 166 mV overpotentials at 10 mA cm-2for OER while only 1.2% performance loss after 1000 cycles in acid medium. The PEM electrolyzers based on RuMnSnOxachieves 1.998 V at 2 A cm-2and stably operate over 50 h. The PEMFC peak power density based on Pt/C + RuMnSnOxcatalyst reaches 2.61 W cm-2and the anti-reversal time reaches 143 min.

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 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.
