Marine sponge skeleton photosensitized by copper phthalocyanine: A catalyst for Rhodamine B degradation

We present a combined approach to photo-assisted degradation processes, in which a catalyst, H and UV irradiation are used together to enhance the oxidation of Rhodamine B (RB).

Description
Summary:We present a combined approach to photo-assisted degradation processes, in which a catalyst, H and UV irradiation are used together to enhance the oxidation of Rhodamine B (RB). The heterogeneous photocatalyst was made by the process of adsorption of copper phthalocyanine tetrasulfonic acid (CuPC) onto purified spongin-based marine sponge skeleton ( S). The product obtained, CuPC- S, was investigated by a variety of spectroscopic (carbon-13 nuclear magnetic resonance C NMR, Fourier transform infrared spectroscopy FTIR, energy-dispersive X-ray spectroscopy EDS) and microscopic techniques (scanning electron microscopy SEM, fluorescent and optical microscopy), as well as thermal analysis. The study confirms the stable combination of the adsorbent and adsorbate. For a 10 mg/L RB solution, the percentage degradation reached 95% using CuPC- S as a heterocatalyst. The mechanism of RB removal involves adsorption and photodegradation simultaneously.
