The nano composite Sn doped ZnO-carbon nano tube nano particles (ZnO-CNT NPs) having peculiar property in various physical science fields has been synthesized using simplified cost-effective spray pyrolysis method which forms the nano powder unusually. The work has been bringing to the fundamental study such as XRD and SEM with EDAX using sophisticated instrument to confirm expected elements present with strong bond by evaluating and serious care on diffraction peaks which becomes sharper, surface morphology and energy dispersive amplitude. All crystal phases are anatase formation and no characteristic peaks of Cu metal or oxide at 2θ values which matches with JCPDS 36-1451corresponding to ZnO and JCPDS 26-1079 corresponding to MWCNT. TEM and SAED investigated the entitled compound that particles size, shape and presence of oxygen under ZnO and carbon nano tubes (CNTs) remand, 2% of Sn was doped with this source solution. CuO was doped with ZnO-CNT play important roles in determining the photocatalytic efficiency and germination effect of them. Particular interest has been paid to improve the photocatalytic activity of semiconductors modified by CuO doped with ZnO-CNT nanospheres, since such nanoparticles are normally of easy preparation and thus hold better potential for practical applications. However, different size effects of NPs have been found for nanomaterials containing noble metal NPs. It has been shown that CuO doped with ZnO-CNT photocatalysts outperform for visible light germination effect of, which indicate that for semiconductors with no significant visible light absorption, larger are able to result in a superior photocatalytic activity under visible light due to stronger region of UV-Vis light.
