Catalysts That Are Less Precious
Precious metals such as iridium, rhodium, and ruthenium are widely used to catalyze chemical reactions, but “precious” means expensive, and for many years chemists have been searching for base metals that can catalyze reactions less expensively.
Successes have been few and far between. But three groups recently developed ways to use the less expensive metals iron and cobalt to catalyze hydrogenations—reactions used to synthesize pharmaceuticals, agrochemicals, and fine chemicals (Science 2013, DOI: . . .
