Reactivity of Pyrite Surfaces With Thiomolybdate as Sorbate
Sorption of a sulfur-molybdenum compound onto pyrite surfaces leads to an enhance capability of pyrite to facilitate the conversion of dinitrogen to ammonia, a key reagent in the formation of amino acids on the prebiotic Earth. The structure and chemical environment of the molybdenum-sulfur surface compound is thought to be similar to molybdenum-sulfur compounds embedded in enzymes, where these compounds facilitate the conversion of dinitrogen to ammonia.
