Molecular Bottom‐Up Design of Single‐Site Copper‐Palladium Catalysts for Selective Glycerol Electro‐Oxidation

Advanced Energy Materials, EarlyView.
A bimetallic Cu‐Pd single‐site catalyst for the selective and efficient electrooxidation of glycerol to formate and C3‐products (lactate, glycolate, glycerate) is reported. Experimental and theoretical studies shed light on the catalyst function and reveal that Pd sites facilitate the adsorption of hydroxyl (C‐OH) species which prevents C‐C bond ...

Metal-Free Dihydrogen Oxidation by a Borenium Cation:A Combined Electrochemical/Frustrated Lewis Pair Approach [PDF]

, 2014
In order to use H2 as a clean source of electricity, prohibitively rare and expensive precious metal electrocatalysts, such as Pt, are often used to overcome the large oxidative voltage required to convert H2 into 2 H+ and 2 e−. Herein, we report a metal-
