A new semiconductor CuPbO nanomaterial has been prepared where lead nitrate and copper nitratewere co-precipitated to form this compound. The high-resolution scanning electron microscopic studiesrevealed that CuPbO possesses a nanobundle flower-like structure. XRD confirmed the occurrence ofCu, Pb & O in the fabricated compound. The size of the nanomaterial is determined for being ~200nm by high-resolution transmission electron microscopic analysis. The photoluminescence analysisshowed the possible electron transfer and crevasses between Cu and PbO causes recombine ofelectron-hole pairs. The ultraviolet-visible diffuse reflectance spectral analysis showed that thenanomaterial has a low band gap energy. The material was found to be a good recyclable photocatalystin the decomposition of diamond green B dye. As a photoelectrode, CuPbO proved its efficiency indye-sensitized solar cell applications.
