Abstract Both ZnO and TiO 2 are common semiconducting metal oxides with high mechanical chemical durability. However, they only have good photocatalytic ability in the UV region, besides rapid recombination between electrons holes reduces efficiency of decomposition organic substances. To improve their catalytic efficiency, this study, were doped B to produce novel B/ZnO/TiO nanocomposites for degrading tetracycline hydrochloride (TCH) aqueous solution. The characteristics samples analyzed by diffuse reflectance ultraviolet–visible (DR/UV–vis), scanning electron microscope (SEM), energy-dispersive (EDS), Fourier transform infrared spectroscopy (FT-IR), x-ray diffraction (XRD) techniques. 3B/ZnO/TiO sample had a band gap energy ( E g ) 3.21 eV. Although tightly aggregated morphology composed many nanoparticles 33–137 nm, it still exhibited higher uniformly than ZnO/TiO . At optimal 3 wt%, degradation (DE) was achieved at 96.33% rate constant 0.067 min −1 factors that affect process such as initial TCH concentration, catalyst content, pH solution comprehensively investigated. In addition, stability nanocomposite evaluated via three consecutive cycles DE 69.75% 3rd cycle. Z-scheme mechanism proposed catalyst. electrical consumption estimated per order 29.05 kW.h.l
