Selective deactivation of gold catalyst
Abstract. The progressive poisoning effect of different molecules on carbon supported gold catalysts has been evaluated during the aerobic oxidation of glucose. A geometrical model has been derived for describing the morphological properties of two catalysts made of carbon supported gold particles having a known size distribution centered at 3.30 and 7.89 nm respectively. The observed deact…

Highly selective oxidation of benzyl alcohol to benzaldehyde catalyzed by bim…
Abstract. The present study focuses on the smooth oxidation of benzyl alcohol by air in a vapor phase process affording benzaldehyde with high selectivity and yield, using mono- and bimetallic gold–copper on silica catalyst. Particularly efficient was the catalyst 1% Au–Cu/SiO2 with the weight ratio Au/Cu = 4, leading to perfume-grade, acid-free benzaldehyde in over 98% yield. Keywor…

Facile synthesis of polyaniline using gold catalyst
Abstract. The oxidative polymerization of aniline was investigated using H2O2 as an oxidant and metallic gold as a catalyst. In the form of colloidal nanoparticles, gold produces the conductive polyaniline only in a low yield, whereas when supported on carbon and titania, it improves the polymerisation reaction. For an Au/TiO2 catalyst, a synergistic effect between the metal and the support…
