Catalysis expert explains how gold might slash China’s mercury pollution
Graham Hutchings of Cardiff University made a discovery in 1982 that came to define his career. He predicted that gold—despite its reputation for being inert—should be an excellent catalyst for an industrial reaction that makes vinyl chloride (chloroethene), used to produce one of the world’s most ubiquitous plastics, polyvinyl chloride (PVC).
