Biosynthesis of nanomaterials has piqued the interest of current researchers due to its low toxicity, reproducibility, environmentally friendly, economic viability, and low energy consumption. In this direction, for the first time, a biosynthesis titanium dioxide (TiO2) nanoparticle was carried out by using Orange leaves (O-TiO2) as reducing agents to synthesize TiO2 from titanium (IV) isopropoxide (TTIP). Furthermore, the effectiveness of synthesized catalyst O-TiO2 for degradation Metronidazole (MTZ) residue from aqueous solution was studied for the first time by changing different initial parameters such as pH (3, 5, 7, 9, and 11), and solar intensity while keeping other parameters constant 15 mg/L of MTZ initial concentration, 30mg/L of O-TiO2 concentration, 200 mg/L of H2O2 concentration, and, and the results confirm the effectiveness of O- TiO2 to remove MTZ as that of commercial TiO2 and the maximum removal percentage was achieved to be 89.12% Its usage as a catalyst is viable because of its low cost and great output rate.
