Synthesis of zinc oxide from oil palm leaves by green sol-gel method: effect of concentration variation

In this study, zinc oxide (ZnO) nanoparticle has been successfully synthesized using oil palm leaves extract (OPLE) as the stabilizing agent Oil palm leaves has been chosen because of its availability in this country as it generated as a by-product of palm oil. ZnO currently has a great potential in food industry for example zinc oxide is used as a food additives due to its antioxidant properties. However, this study is focusing more on food packaging application as it is one of food safety requirement. Thus, as the aim for this study, to characterize the OPLE should be done to study the functional group contain in the OPLE by using FTIR analysis. Green sol-gel method also has been chosen during synthesizing ZnO to study the effect of concentration variation to the physical properties of ZnO using FTIR and XRD analysis.
