Fabrication of H3PW12O40-doped carbon nitride nanotubes by one-step hydrothermal treatment strategy and their efficient visible-light photocatalytic activity toward representative aqueous persistent organic pollutants degradation

- 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.
