Samenvatting:Title screen
Selective oxidation of long chain alkanols (+C8+) has deserved much less attention than that of more reactive benzylic or C1–C4 aliphatic alcohols. Supported gold nanoparticles (NP) are active for the oxidation of alcohols under green chemistry conditions, and high surface supports are used to maximize and stabilize their dispersion. In this work, we investigate hexagonal mesoporous silicas (HMS), pure or modified with metal cations having redox properties (Ce, Fe), as supports of gold NP catalysts for the aerobic oxidation of 1-octanol under green process conditions. Two ways of support modification were used, say, by introducing the modifying cations during the HMS synthesis or by post-synthesis impregnation.
