摘要：

Sol-gel derived CuO-TiO2 core shell nanocomposites were synthesized by modified Stober method [1] and characterized. XRD analysis revealed dominant evolution of CuO (tenorite phase) at the core on to which TiO2 (anatase) was coated. The average crystallite size, estimated from Scherrer's computations was 30-33 nm. PEC studies indicated that core shell composites offer significant photocurrent. The effect of variation in concentration of titanium (IV) butoxide (precursor used for generating TiO2 coat over CuO) was also investigated. The increase in concentration of TBOT led to increase in photocurrent.
