NOVELTY - Synthesizing Syzygium cumini leaves extract based stannic oxide and titanium dioxide decorated reduced graphene oxide, comprises: mixing (stannic oxide and titanium dioxide nanoparticles) reduced graphene oxide in 5:1 ratio and shaking for 25 minutes at room temperature; and sonicating the mixture for 2 hours and then drying in hot air oven, so as to obtained stannic oxide and titanium dioxide decorated reduced graphene oxide. USE - The method is useful for synthesizing Syzygium cumini leaves extract based stannic oxide and titanium dioxide decorated reduced graphene oxide. ADVANTAGE - The method is: environmentally friendly and efficient method; simple operative synthetic technique; applicable in large scale operations; and optimization of reaction parameters. The method provides Syzygium cumini leaves extract with photodegradation efficiency.
