To catalyze this process, Alwin Mittasch found that iron oxide is a cheaper option than osmium and ruthenium. The product of this process is used in a two-step process, which oxidizes this process's product and re-oxidizes the result, after which water absorbs the nitrogen dioxide to produce nitric acid in the Ostwald process. About one-half of the protein consumed in the world is synthesized using fertilizer that results from this process, which uses hydrogen and nitrogen. For 10 points, name this process that synthesizes ammonia, named for two Germans.
