Photocatalytic degradation of glyphosate using Ce/N co-doped TiO2 with oyster shell powder as carrier under the simulated fluorescent lamp

Glyphosate is currently one of the most used organophosphorus herbicides in world and its accumulation translocation soil wave causes environmental pollution biological health problems. A new approach to problem provided by preparation cerium nitrogen co-doped titanium dioxide composite nano-photocatalysts loaded on modified oyster shell powder (CeNT@Oys) a simple hydrothermal synthesis. The physicochemical optoelectronic properties are analyzed using SEM, BET, XRD, Raman, FTIR, UV-vis DRS, XPS characterization techniques range photoelectrochemical techniques. results show that addition increases specific surface area, while Ce-N-TiO 2 an anatase crystal composed Ce doped form interstitial surface, N, co-doping N elements gives it property being excited visible light. photocatalytic activity different catalysts was evaluated degrading 50 mg/L glyphosate solution under simulated sunlight. catalyst determined be reusable five repeated degradation experiments. Based quenching experiments electron paramagnetic resonance tests, effective active species degraded mechanism photocatalyst proposed. Finally, pathway for PMG CeNT@Oys HPLC-MS/MS determine intermediate products.
