Environmental friendly synthesis of TiO2-ZnO nanocomposite catalyst and silver nanomaterilas for the enhanced the production of biodiesel from Ulva lactuca seaweed and potential antimicrobial properties against the microbial pathogens

In this study, biodiesel was produced from Ulva lactuca seaweeds using TiO2–ZnO nanocomposite catalysts with particle size of ~12 nm. The size controlled TiO2–ZnO nanocomposite was characterized by powder XRD analysis and TEM. The result of that TiO2–ZnO catalyst is a promising catalyst for the production of biodiesel under mild reaction conditions and high yield of hydroxydecanoic acid conversion of 82.8%. The various conditions optimized for the higher conversion to FAME (15.8 ml of FAME) were 4 wt% catalysts at 4 h under 60 °C and further there is no increase of conversion to FAME above 60 °C–80 °C. The total product yield was calculated as 82.8% of conversion to FAME. The evaluated biodiesel was found to be up to the mark of ASTM standards. The silver nanoparti...
