Ruthenium supported ZnO catalyst for aerobic oxidative transformation of alcohols and its antibacterial studies

Pure ZnO and (Ru-Mn)ZnO, (RuxMnyZn(1-y)-xO, x=0.01; y=0.01, 0.02 and 0.03) were synthesized by sol-gel method. The effects of codoping on structural, morphological, catalytic and antibacterial activities were studied. From the physico chemical characterizations, it is found that the average particle sizes of the synthesized catalysts are between 20 and 30nm and exhibits a single phase nanostructures. The aerobic oxidative organic transformations of alcohols (benzyl alcohol, cyclo hexanol, cinnmyl alcohol, n-propanol, n-butanol) in liquid phase with 30% H2O2 as co-oxidant were tested against new ternary (Ru-Mn)ZnO metal oxides. (Ru-Mn)ZnO catalysts shows good percentage yield with compared to pure ZnO. In order to examine the bacterial activity, in vitro antibacterial screenings for the metal oxides were tested against human pathogenic Gram +ve (S. aureus) and Gram –ve (E. Coli).Pure ZnO and (Ru-Mn)ZnO, (RuxMnyZn(1-y)-xO, x=0.01; y=0.01, 0.02 and 0.03) were synthesized by sol-gel method.
