Cutting out the coke : The concept of catalytic oxidative dehydrogenation by using solid oxygen exchangers and a solvent‐free parallel synthesis of a set of ten bimetallic catalysts is described. The compounds were tested in the selective oxidation of hydrogen in the presence of ethane and ethylene (HCs) at 600 °C. Cerium tungsten oxide was found to be a superb rechargeable “oxygen reservoir” (see picture), with 97 % chemoselectivity and negligible coking levels.
