Growing interest for biomass valorization approaches in the recent years has led to an increase of research related to the application of gold catalysts in the transformation of biomass-derived compounds. Gold catalysts have demonstrated outstanding performance in a number of reactions. Applications of gold as a catalyst have several advantages, such as stability under oxidative atmosphere, high selectivity toward products of partial oxidation and hydrogenation, as well as acetalization and isomerization. Moreover, gold catalysts allow operation at mild and therefore environmentally friendly conditions, using molecular oxygen as an oxidant, lower pressure and temperatures, and in some cases water as a solvent. More efforts should be however devoted to elucidating long-term stability of gold catalysts and in case of deactivation, development of efficient catalyst regeneration methods. Due to a synergetic effect, bimetallic gold catalysts in some cases have higher activity. Thus, addition of such metals, as copper could increase the process profitability.
