“…[57,58] Cao and co-workers performed an extensive study on TiO 2 supported Au catalysts prepared via solimmobilisation method. [59] Metal particle size and capping agent amount were the parameters that mostly affected the catalyst activity. In particular, the presence of capping agent surrounding the Au particles can limit the diffusion of substrate to the active site, thus strongly limiting the final activity.…”

Biomass constitutes a renewable source for new chemical platforms. Among other processes the catalytic ones represent a green alternative when active and selective catalysts can be developed. In this paper, applications of gold and gold‐based catalysts have been reviewed in the field of the selective oxidations. Indeed, from the discovery of the peculiarity of gold as catalytic material, the liquid phase oxidations have been differently viewed. Three important biomass‐derived molecules, namely glucose, hydroxymethyl furfural (HMF) and glycerol have been considered as precursors for products of industrial interest where gold catalysts have played an important role. This review starts from the research on monometallic gold catalysts which have been explored initially and then look at gold as modifier of other metal catalyst. This latter field is still in evolution and probably needs to be look at in the future.

“…In the past the oxidation of glucose, the eminent member of that family, has for long time been investigated using Pt group metals as the catalyst. The influence of different supporting materials on catalytic activity was tested in several papers, [147][148][149][150][151][152][153] and reproducibility of morphology and catalytic performance were demonstrated in 5-500 g scale preparations. Sophisticated bi-and tri-metallic catalysts have been proposed to overcome these effects.…”

This critical review covers the recent development of the catalytic properties of gold in the selective oxidation of organic compounds, highlighting the exciting contribution to the art of catalysis. The unique, outstanding properties of nanometre-scale particles of gold, a biocompatible non-toxic metal, have allowed the development of a new generation of stable and selective catalysts for the conversion of many organic feedstocks to valuable chemicals. A critical discussion of the results of different research groups is presented along with attempts to correlate the catalytic properties with catalyst morphology in non-equivalent series of experiments. Particular emphasis has been given to the international efforts towards optimised synthesis of products of industrial appeal such as propylene oxide, vinyl acetate monomer, cyclohexanol/cyclohexanone, gluconic acid and glyceric acid (168 references).

Die Gold‐katalysierte Selektivoxidation von Aldehyden und Alkoholen zu den korrespondierenden Carbonsäuren kann für die Funktionalisierung verschiedener Substanzen auf Basis nachwachsender Rohstoffe, z. B. Kohlenhydrate oder Fettalkoholethoxylate, in Zukunft große Bedeutung erlangen. Bei der Kohlenhydratoxidation weisen Goldkatalysatoren eine sehr hohe Aktivität sowie eine exzellente Selektivität und Langzeitstabilität auf und erlauben somit eine hocheffiziente Herstellung verschiedenster Aldonsäuren. Auch bei der Selektivoxidation von Ethoxylaten zeigen Goldkatalysatoren, dass diese universell, mit guter Aktivität und sehr guter Selektivität zu den entsprechenden Ethercarbonsäuren umgesetzt können.
