Front Cover: Green Oxidation of n‐Octanol on Supported Nanogold Catalysts: Formation of Gold Active Sites under Combined Effect of Gold Content, Additive Nature and Redox Pretreatment (ChemCatChem 6/2019)

Abstract

The Front Cover shows the reaction pathway of n-octanol oxidation over supported nanogold catalysts in front green leaves and the outline of chemical plant. In their Full Paper, E. Pakrieva et al. investigated the combined influence of gold content, modifying additives and redox pretreatments on catalytic properties and formation of active sites of Au/TiO2 in the selective oxidation of n-octanol under mild conditions. They found that the order of catalytic activity depended on the support nature for all treated samples. The catalytic activity increased with the increase of gold loading in the samples with hydrogen pretreatment, while after the oxidative pretreatment of the catalysts the opposite dependence of the activity with the gold content was found. This catalytic behavior was explained by a change in the surface concentration of monovalent gold ions, which seemed to be the active sites. More information can be found in the Full Paper by E. Pakrieva et al. on page 1615 in Issue 6, 2019 (DOI: 10.1002/cctc.201801566).
