Apparently this particular catalyst is pitched as an H2 evolution catalyst by oxidizing alcohols... can anyone with access to the article tell me where that energy comes from (thermo- or electrocatalytic)? IIRC alcohol dehydrogenation is endothermic by like 15-20 kcal/mol. A 1->2 reaction has an entropy change of ~30 eu, so quick math and dirty looks from p-chemists gives an operating temperature somewhere around 300 °C. That's quite a bit better than conventional crackers but still requires significant thermal encouragement...
