Promotion of nitrogen and hydrogen chemisorption and ammonia synthesis on alumina-supported hexagonal tungsten bronze, Kx WO3

Abstract

Alumina-supported hexagonal Kx WO3 phases have been prepared in the presence and absence of Pt; K significantly promotes the chemisorption of nitrogen and Pt the chemisorption of hydrogen thereon. The turnover number for the production of ammonia (molecules of ammonia produced per site capable of chemisorbing hydrogen per second) was very low, but was promoted by K and not Pt. The modes of adsorption and catalysis and the manner of their promotion are considered in detail.
