The water–gas shift reaction (WGSR) of carbon monoxide and water to give carbon dioxide and hydrogen [Eq.(1)] is a very important industrial process.[1] For instance, it plays a major role in steam reforming of alkanes to produce hydrogen. Therefore, it is the basis of important bulk hydrogenation processes, most notably the catalytic reduction of molecular nitrogen to form ammonia in the Haber-Bosch process.[2]
