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 .
