Photo catalytic degradation of Direct yellow ۵۰ dye DY from aqueous solution utilizing ZnO/ MWCNTs nanocomposite under Irradiation of Solar Light was studied in the research. First, ZnO/MWCNTs nanocomposite was synthesis via hydrothermal method. he integration of MWCNTs into ZnO NPs structure resulted in increased roughness and porosity, thus improve active sites onto nanocomposite, which can enhancement of effective surface area, Characterized via different techniques, like FESEM, TEM, and BET. Response surface methodology (RSM) approach were using in this study. Several factors such as Nano catalyst quantity, concentration of DY dye, was best Optimal conditions to examine the best degradation capacity for DY dye with solar light source. In with light, best degradation capacity was observed at ۰.۳ g of ZnO/ MWCNTs nanocomposite for concentration ۳۰ mg/L at ۲۵ °C with ۱h Irradiation time. Photo catalytic degradation complete after that ۶۰ minutes of solar light irradiation, percent ۹۳.۵۶ % degradation efficiency of DY dye was obtained, Thus, appear capability of nanocomposite to removal of on DY dye from wastewater. As a result, successfully syntheses a new form of ZnO nanoparticles embedded with MWCNTs. ZnO/MWCNTs, which may be utilized photocatalytic degradable of DY dye. According degradation results, DY dye might be effectively degradation from aqueous solutions utilizing ZnO/ MWCNTs nanocomposite.
