Here in, we report the synthesis and characterization of ZnO–TiO 2 composite as a potential photo catalyst for photo degradation of methyl orange under UV irradiation. ZnO–TiO 2 with 1:1 ratio was synthesized via wet incipient impregnation method using TiO 2 and Zn(NO 3 ) 2 ⋅ 6H 2 O as precursor material and the prepared composite was characterized by XRD, EDX and SEM. The synthesized composite was employed as photo catalyst for photo degradation of methyl orange. The photo degradation results showed that ZnO–TiO 2 exhibited better catalytic performance than ZnO and TiO 2 alone. The methyl orange photo degradation efficiency was determined to be 98, 75 and 60% over ZnO–TiO 2 , ZnO and TiO 2 respectively using 50 mL solution of 100 mg/L at 40 °C for 120 min. The ZnO–TiO 2 catalyzed photo degradation of methyl orange followed pseudo-first-order kinetic in terms of Langmuir–Hinshelwood mechanism.
