The surge of toxic contaminants and harmful microorganisms in aquatic environment have posed irreparable and deplorable impacts to human health and progressively disturbance to ecosystem and environment. Herein, we have successfully devised a novel visible light S-scheme Fe 2 WO 6 /SrTiO 3 composite using a two-step hydrothermal technique and tested by myriad material characterization methods. An intimate contact and a heterojunction constructed between Fe 2 WO 6 nanoparticles and cube-like SrTiO 3 has been verified by microscopic images. The as-synthesized composite exhibited enhanced light absorption and lower charge carrier recombination rate as demonstrated by UV–vis absorption spectra and photoelectrochemical data. Under visible light exposure, 20 wt% Fe 2 WO 6 /SrTiO 3 displayed the best photodegradation of Rhodamine B and the apparent rate constant of which was 1.9 and 2.7 times higher than those of pristine Fe 2 WO 6 and pristine SrTiO 3 , respectively. The boosted photoactivity of the composite can be attributed to the superior charge carrier segregation efficiency and high redox capabilities resulted from S-scheme heterojunction. A stable photocatalytic performance of Fe 2 WO 6 /SrTiO 3 was also found after fifth cyclic runs. Moreover, the mineralization efficiency of real printed ink wastewater treatment over Fe 2 WO 6 /SrTiO 3 was scrutinized by chemical oxygen demand analysis. Excellent antibacterial property of Fe 2 WO 6 /SrTiO 3 has been confirmed from its destructive action against Escherichia coli and Bacillus cereus . Furthermore, the comprehensive photodegradation mechanism was elucidated in detail. • Cube-like V 2 O 5 loaded with Fe 2 WO 6 was fabricated using a facile route. • Fe 2 WO 6 extended the visible light photoresponse range in the composite. • Photoelectrochemical outcomes signified the composite with good electronic trait. • Composite showed profound photocatalytic performance and antibacterial behavior. • S-scheme composite restrained charge recombination and retained high redox ability.
