Catalysis using gold containing materials
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.
Five topics will be presented. The first
three parts will describe three facets of monometallic gold catalysts. (1) CO oxidation and the hierarchy of
activity of gold species supported on a reducible oxide Fe2O3;(2) acetylene hydrochlorination for the
manufacture of vinyl chloride monomer using highly dispersed gold cations
supported on carbon; (3) methane oxidation using molecular
oxygen with gold nanoparticles dispersed on the zeolite H-ZSM-5. These first
three parts will emphasise that the active species of a gold catalyst is
dependent on the reaction being catalysed and it is not a one size fits all for
this catalysis. The final two parts will discuss gold palladium bimetallic
catalysts. (4) alcohol oxidation and the new
Cooperative Redox Enhancement effect (CORE); and (5) the use of in situ generation of
hydrogen peroxide to enable new oxidative cascade processes. Taken together
these examples will demonstrate the rich tapestry that catalysis by gold can
provide to the catalysis community globally, both from an academic and an
industrial perspective as well as the societal impact that has been achieved by
the commercialisation of gold catalysts .

Professor of Chemistry at Cardiff University 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, a Founding Fellow of the Learned Society of Wales in
2010, a Fellow of the Royal Academy of Engineering in 2023 and an Honorary
Fellow of the Chinese Chemical Society in 2023. He was awarded the Davy Medal
of the Royal Society in 2013, the ENI Award for Advanced Environmental
Solutions in 2017, a CBE in 2018 and the Michel Boudart Award in 2021.
