Abstract:
Revealing how to rationally select a suitable dopant or the host counterpart is greatly important for optimizing the catalytic activity of transition metal oxides (TMOs). We systematically report the adsorption trends of atomic O and H, two selected representative adsorbates, on numerous doped rutile-type TMO surfaces under two different doping modes, aiming to demonstrate adsorption energy (AE) variations of different adsorbates across doped TMO surfaces. A "host-guest interaction" induced adsorption tuning rule for the ternary doping systems is identified, which rationally directs the proposal of cost-effective Ir-doped CrO2 or MnO2 catalysts for the electrocatalytic oxygen evolution reaction compared with the common IrO2.

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...
