Photocatalytic degradation and mineralization of perfluorooctanoic acid (PFOA) using a composite TiO 2 -rGO catalyst.
Journal of Hazardous Materials(2018)
摘要
•Photocatalytic decomposition of PFOA using a TiO2-rGO catalyst was studied.•TiO2-rGO catalyst (0.1gL−1) allowed 93±7% PFOA removal under UV–vis irradiation.•Formation of intermediate PFCAs and F− elucidated the PFOA degradation mechanism.•Faster degradation kinetics were observed for shorter carbon-chain PFCAs.
