<p>Introducing heterostructure to graphitic carbon nitrides (g-C<sub>3</sub>N<sub>4</sub>) can improve the activity of visible-light-driven catalysts for efficient treatment of multiple toxic pollutants in water. Here we report for the first time that a complex material can be constructed from an oxygen-doped g-C<sub>3</sub>N<sub>4</sub> and MIL-53(Fe) metal-organic framework using a facile hydrothermal synthesis and recycled polyethylene terephthalate from plastic waste. The novel multi-walled nanotube structure of the O-g-C<sub>3</sub>N<sub>4</sub>/MIL-53(Fe) composite which enables unique interfacial charge transfer at the heterojunction showed an obvious enhancement in separation efficiency of the photochemical electron-hole pairs. This resulted in narrow bandgap energy (2.30 eV compared to 2.55 eV in O-g-C<sub>3</sub>N<sub>4</sub>), high photocurrent intensity (0.17 mA cm<sup>-2 </sup>compared to 0.12 mA cm<sup>-2</sup> and 0.09 mA cm<sup>-2</sup> in MIL-53(Fe) and O-g-C<sub>3</sub>N<sub>4</sub>, respectively), and excellent catalytic performance in the photodegradation of anionic azo dyes (95% RR 195 and 99% RY 145 degraded after 4 h, and only a minor change in the efficiency observed after four consecutive tests). These results demonstrate the development of new catalysts made from waste feedstocks that show high stability, ease of fabrication and can operate in natural light for environmental remediation.</p>
