摘要:Catalysis is of crucial importance for the manufacture of the goods and infrastructure necessary for the effective wellbeing of society. Catalysis underpins the manufacture of most goods as they need a catalyst for their manufacture at some point. In this way catalysis contributes towards over 25% of global domestic product. Hence designing new catalysts is a topic of intense research interest in the scientific community. For example, the identification that gold in nanoparticulate form is an exceptionally effective redox catalyst has paved the way for a new class of active catalysts. Gold is the most active catalyst for acetylene hydrochlorination and recent research on this will be described. Alloying gold with other metals can enhance the activity and these catalysts are effective for the oxidation of alcohols and hydrocarbons as well as the direct synthesis of hydrogen peroxide. In this presentation, the use of AuPd colloids for the selective oxidation of hydrocarbons will be used as an example of bimetallic catalysts and aspects of the latest research on topics involving new nanomaterials will also be presented.

Keywords: Catalysis; Gold Nanoparticulate; AuPd colloids; Oxidation of Hydrocarbons; Synthesis of Hydrogen Peroxide;

Graham Hutchings is Regius Professor of Chemistry at Cardiff University and Director of the Cardiff Catalysis Institute. He studied chemistry at University College London. His early career was with ICI and AECI Ltd. where he became interested in gold catalysis. In 1984 he moved to academia and has held chairs at the Universities of Witwatersrand, Liverpool and Cardiff. He was elected a Fellow of the Royal Society in 2009, a Member of Academia Europaea in 2010. He was awarded the Davy Medal of the Royal Society in 2013, the ENI Award for Advanced Environmental Solutions in 2017 and a CBE in 2018.
