Opis

Since the first report on alcohol oxidation in 1998, many studies have highlighted some peculiarity of gold with respect to other metals. Some analogies have been found between gas and liquid phases, but the big challenge to operate in a condensed phase lies in the role of the solvent in tuning the reactant catalyst contact. Liquid-phase oxidation has numerous applications. However, many studies on gold catalysts have been devoted to gas-phase reactions. Only recently has the scientific community approached gold-catalyzed liquid-phase oxidation. This complete, exhaustive book covers the topic of gold-based catalyst applications in selective oxidation in the liquid phase. It presents a rational state of the art and will be useful for researchers, even those not yet involved in the field."
