TiO2 nanomaterials were developed using sol-gel method. CuS nanomaterials were synthesized using hydrothermal method. Then TiO2/CuS composite nanomaterials were synthesized. These samples were analysed for their electrochemical, optical, morphological and structural properties. X-ray diffraction and field emission scanning electron microscopy confirmed the successful formation of desired crystal phases and surface morphologies. Optical characterization revealed promising band gap energies and light absorption capabilities while electrochemical tests indicated improved photoactivity and stability. The comparative study of TiO2, CuS and TiO2/CuS composite nanomaterials shows improved results in the composite form.en-USKeywords:Composite nanomaterialssol-gel methodhydrothermal methodband gapX-ray diffraction studiesArticle
