Synthesis of Carbon-ZnO nano composites as pollution sensors to dyes removal

The Waste water treatment in the presence of different types of laser. It was synthesized of (C/ZnO) nano composite using hydrothermal method with different ratios of carbon (as a precursor of sugar). The prepared (C/ZnO) Nano composite were calcined at (500) °C for 1 hr. X-ray diffraction (XRD), Field-emission scanning electron microscopy (FE-SEM), zeta potential and Ultra-violet Visible (UV-Vis) Spectrophotometer were characterized by the optical morphological structure and properties such as crystalline structure, morphology and band gap of the synthesized sample. The results of XRD measurement indicated that the (C/ZnO) nano composite is reduced in the crystallite of the ZnO with the increase in the carbon ratio. The FE-SEM measurement presented an evidence of high contact with the crystallite size. The morphology of C/ZnO nano composite which takes architecture structure and obviously demonstrates aggregation of the particlesIt can be concluded that in the wurtuze process, all nano composites prepared have small nanoparticles crystallized. The UVA photo catalytic activity is evaluated by photo (maxilon blue dye) catalytic decomposition of the dye GRL in aqueous solutionsThe color of the solution mixture (as well as the aliquots) changed from blue to white due to gradual deterioration of the dye with consecutive flashes. That change in color as dye for aqueous solution (water treatment and environmental protection) under laser Nd:YAG (1064 nm), the photo catalytic activity for dye removal as a function of time was monitored by using UV(390 nm). Results show that C-doped ZnO exhibit a significantly enhanced photo catalytic activity due to the improved absorption in the UV and visible-light region.
