To overcome the hard and costly post-treatment separation of ultrathin graphitic carbon nitride nanosheets (UGCN), it was supported on polyurethane foam (PUF). The ratio of PUF/UGCN was optimized for the removal of a mixture of methylene blue (MB) and methyl orange (MO) dyes. The characteristics of the composite photocatalyst and its photocatalytic performance were detailly studied. The X-ray diffraction and Fourier transform infrared results proved the successful preparation of UGCN and PUF and that the PUF/UGCN composite combines the features of both pure materials. The transmission electron microscopy illustrated the ultrathin nanosheet shape of the UGCN, while the scanning electron microscope showed the highly porous 3D-hierarchical structure of PUF. Compared to the pure components, the composite photocatalyst with PUF/UGCN mass ratio of 4 achieved better decolorization of MO and almost same decolorization of MB as UGCN. Neutral pH and 1 g/L of the composite photocatalyst were the optimum conditions for MB/MO mixture decolorization. The composite photocatalyst kept its efficiency for five successive cycles. Hydroxyl radicals were the dominant in the degradation of MB, while superoxide radicals were the most influencer in MO degradation. Conclusively, supporting UGCN onto PUF kept the photocatalytic efficiency of UGCN toward MB decolorization and improved its efficiency toward MO. Moreover, it enabled the reuse of the composite photocatalyst and facilitated the post-treatment separation process.

“…[ 3–5 ] Among them, photocatalysis featured by high efficiency, low cost, energy saving, and lack of secondary pollution is an attractive potential strategy to solve the above worsening environmental issues. [ 6–8 ] Though many high‐performance photocatalysts with high light absorptiveness, sufficient charge isolation, and rapid surface reaction kinetics have been developed, [ 9–12 ] the photocatalytic materials are mainly used as powder particles, which have low activity, easy agglomeration and secondary pollution caused by difficult recovery of materials, limiting their practical application. Thus, the development of photocatalysis‐based combined water treatment technology and engineering application mode is highly desirable.…”

Titanium isopropoxide and sewage sludge from a municipal wastewater treatment plant were used as precursors to synthesize TiO2 deposited on activated sludge (TiO2/AS) using the sol‐gel method. The sewage sludge acted as a novel substrate to increase the surface area and as source of metals and non‐metals, which doped into the TiO2 lattice to enhance its photocatalytic activity. Thus, the synthesized TiO2/AS exhibited a narrow bandgap energy (2.61 eV) and a high surface area (138.7 m2g−1) for increased photocatalytic degradation with high mineralization of tetracycline in an aqueous environment. The study also demonstrates that the kinetics of photocatalytic tetracycline degradation by TiO2/AS follows a pseudo‐first‐order model. The optimized pH for the photocatalysis by TiO2/AS was 8.
