摘要：

CuO-TiO2 nanocomposite prepared by sol-gel method does not photocatalyze dye degradation under UV-A as well as visible light. Powder X-ray diffractogram shows the presence of monoclinic CuO and anatase TiO2 in the nanocomposite. The composite displays photoconductance confirming photogeneration of charge carriers. Absence of photocatalysis is attributed to CuO-mediated electron-hole recombination.
