Recent Advances in Supported Gold Nanocatalyst

Dear Colleagues,

For the past few centuries, bulk gold was regarded as a catalytically-inert material. However, gold catalyst was first used as a hydrogen oxidation catalyst in 1906 by Bone and Wheeler. Then, in 1925, Bone and Andrew reported gold-catalyzed CO oxidation. In the 1950s and 1960s, gold was mainly used as a hydrogenation catalyst. In the 1970s, Bond, Sermon, and Paravano reported that small dispersed gold particles, supported on different metal oxides (MgO, Al2O3, and SiO2) exhibited high catalytic activity toward the hydrogenation of alkenes at very low temperatures (e.g., 373 K). These results were later used to develop a model for the mechanism of heterogeneously catalyzed CO oxidation. In the last decade, the main focus was on the reactivity of small gold supported on metal oxide nanocatalysis (“Gold Rush”). In 1987, a breakthrough was made by Haruta, where nanogold supported on transition metal oxides was proven to play a significant role in the field of heterogeneous catalysis, especially for room temperature CO oxidation. Since then, supported gold nanocatalysts became one of the hottest topics in chemistry and was considered to be the basis of gold nanocatalysis research in the scientific world.

This Special Issue aims at reporting recent advances in the synthesis of novel supported gold nanocatalysts with high activity and stability for many catalytic and photocatalytic reactions. Moreover, potential applications, kinetics, reaction rates, reaction mechanisms, active sites, nature of support, gold-support interaction, preparation conditions, surface aria, heat treatment, as well as the morphology of the catalyst and its effect on catalytic activity and stability, are valuable subjects for this Special Issue.
