Catalysis by Metals: The R H. Emmett Award Address

It is a pleasure to receive the second Paul H. Emmett Award in Fundamental Catalysis and to have the opportunity to present this address. The subject, catalysis by metals, is one in which Professor Emmett himself has contributed extensively. His long-standing interest in the iron catalysts for ammonia synthesis, and also his later interest in metal alloy catalysts, are well known.
