Herewith, we approached a synthesis of new biphenyl porphyrin derivative and confirmed its structure with H-NMR and C-NMR studies, FT-IR and mass analytical methods. The porphyrin derivative grafted with TiO₂ and the composite (PORBP-TiO₂) was further confirmed with different analytical techniques like diffuse reflectance spectra, XRD, FT-IR, XPS, SEM analysis. PORBP-TiO₂ was checked for photodegradation of methylene blue in visible light condition and degradation results were compared with bare TiO₂. Our newly synthesized photocatalyst showed a very fast and efficient photocatalytical activity in comparison with bare TiO₂. Fluoresence life time results also supported the strong photocatalytic activity of PORBP-TiO₂. The reusability studies also showed that PORBP-TiO₂ is having very good stability upto 10 cycles also. Finally we proposed a suitable catalytic diagram for PORBP-TiO₂ photocatalysis.

Interfacial solar vapor generation (ISVG) accompanied by photocatalytic degradation holds immense potential to mitigate water scarcity and pollution. Distinct from the two detached functional components (photothermal agent and photocatalyst) in a conventional evaporator, in this study, an all-in-one photothermal/catalytic agent, nitrogen-containing honeycomb carbon nanosheets (NHC), was engineered for synergistic high-efficiency steam generation and photocatalysis functions. It was demonstrated that the superoxide radical generated on the surface of NHC conferred its catalytic activity to the photodegradation of organic pollutants under full solar spectrum irradiation.
