Stretching metals can tune catalysis: A new method predicts energy shifts‎

Heterogeneous catalysis—in which catalysts and reactants are of different phases, e.g., solid and gas—is important to many industrial processes and often involves solid metal as the catalyst. Ammonia synthesis, catalytic converters for automobile exhaust, methanol synthesis, carbon dioxide reduction, and hydrogen production are examples of such metal-catalyzed heterogeneous catalysis.
