Abstract

A general introduction to environmental catalysis using supported gold and gold bimetallic alloy nanoparticles is presented. The general concepts of environmental catalysts are discussed and then two examples are described in more detail. The possibility of using sustainable feedstocks for the generation of chemicals is also considered. The modern chemical industry has been built up on processes that utilise key platform chemicals, e.g. ethene, propene, benzene and xylenes. These are readily derived from oil. Alternatively, natural gas can be steam reformed to give synthesis gas which provides an additional route to alcohols and hydrocarbons. While it is feasible that biomass can be converted to syngas and hence to existing key platform chemicals, this loses all of the chemical complexity that is inherent to bio‐derived molecules. However, bio‐derived sustainable feedstocks contain excessive levels of oxygen, and de‐oxygenation and dehydration reactions are required. In this chapter the general field is introduced and, in particular, the oxidation of glycerol using supported gold and gold bimetallic nanoparticles is described. In addition the use of solvent‐free reaction conditions is also discussed.
