Photoactive polymer–nanoclay hybrid photosensitizer for oxidation of phenol in aqueous media with the visible light.

Highlights: [•] The hybrid photosensitizer was obtained using pegylated porphyrin and a nanoclay. [•] The pegylated porphyrin intercalated into the nanoclay. [•] The photosensitizer generated singlet oxygen which could oxidize phenol. [•] The efficiency of phenol photooxidation depended on pH. [•] The photosensitizer could be reused.
