H3PW12O40/C3N4 NTs were firstly fabricated by one-step hydrothermal treatment.
The morphology, composition, and optoelectronic property were well characterized.
Target aqueous POPs were successfully degraded under visible-light irradiation.
High activity is attributed to tubular nanostructure and enhanced quantum efficiency.
High stability is attributed to strong interaction between H3PW12O40 and C3N4 NTs.
