Abstract

XRD results showed that TiO₂ exhibited crystalline properties ana the peaks at 2�?¸ values of 25.63�?°, 37.5�?° and 48.4�?° can be indexed to the (102), (005) and (200) planes of anatase titania. The XRD emissions from the rutile phase showed that TiO2 disappear in the TiO2 /CdS nanocomposite since anatase from is is dominated in TiO₂. Vey low platinum signals was detected from TiO2 /CdS/Pt since the platinum percentage is low. HR-TEM image of the TiO2 /CdS nanocomposite exhibited that it was accumulated on a copper grid. SEM images exhibited that Pt nanoparticles are homogeneously dispersed over GO. HAADF images of the TiO2 /CdS/rGO/Pt nanocomposite exhibited that both Pt and TiO₂/CdS nanoparticles are supported on the surface of GO. The effcts of increasing TiO₂/CdS/GO/Pt nanocomposite concentration (0,1;0,2;0,5 and 1 mg/l), GO percentages ( 5%, 10%,15%,20%), sunligth powers( 1 W/m2; 3, 5 , 10 and 15 W/m2), sunligth duration ( 10 min,20,40,50 and 70min) on the methane production from waste CO2 was investigated. Furthermore, the effects of waste CO₂concentrations on the methane production was studied. A cost analysis was performed for methane production from CO₂. After 50 min illumination time at a 0,5 mg/l TiO2 /CdS/GO/Pt nanocomposite dose at a GO percentage of 10%, at a sunligth power of 1 W/ m2 from 10 mg/l CO2 gas 35 mg/day CH4 gas was produced. Keywords: TiO₂/CdS/GO/Pt nanocomposite, Methane, Waste CO₂, Photooxidation.
