Moringa leaves were collected from a farm in Kaduna metropolis and washed to remove impurities. 100g of the leaves were pulverized using mortar and pestle and then placed into 3000ml of beaker. The 1000ml of deionized water was added and was placed on a magnetic stirrer and then boiled to extract the Phytochemical in the leaf. 25 ml of plant extract was added to 250 ml 0.5 M Zinc acetate dihydrate, both when mixed have a pH 6.4. then 0.5M NaOH was added in drop to maintain pH at 8, then the mixture was stirred and heated at 70 °C for 30 min for complete reduction and formation of a white precipitate. The resulting white precipitate was then washed with double distilled water to remove any impurities and oven dried at 75 °C for 6 hours to yield powdered of Zinc Oxide (ZnO) nanoparticles.
