Green-synthesis of CuO-doped SnO₂ nanoparticles using pelawan (Tristaniopsis merguensis) leaf extract

CuO-doped SnO2 nanoparticles were successfully synthesized using biosynthetic methods with the pelawan leaf extract. This method is a modification of the sol-gel process by utilizing antioxidant compounds from the leaf extract as a trap-matrix for tin oxides. This research was conducted based on variations in CuO doping. The characteristics of tin oxide observed in this study were a phase, crystallite size, and crystallinity, which determined based on x-ray diffraction method. It is expected that the method proposed in this study can be developed to synthesize SnO2 nanoparticles that are environmentally friendly. (paper)
