(Phys.org)—Researchers report the discovery of a cobalt-ligand catalyst system that serves as a homogeneous catalyst for the hydrogenation of esters and carboxylic acids to alcohols. Ties J. Korstanje, Jarl Ivar van der ...
(Phys.org)—Catalysts are substances that speed up the rates of chemical reactions without themselves being chemically changed. Industrial catalysts come in two main types - heterogeneous, in which the catalyst is in a different ...
