“…Other researchers have loaded semiconductor with carbon-based nanomaterials like activated carbon, CNTs, graphene, graphite, and other matrices to improve the photocatalytic activity or cycling and its ratings performance [299–302]. Meanwhile, recent research has indicated that organic polymer films such as chitosan and cellulose films can ensure the stabilization of semiconductors especially in nanosized form and also provide an interface for the charge transfer and correspondingly improve photocatalytic efficiency [301–303]. In addition, the incorporation of such biopolymers assist in reducing the leakage of semiconductor particles in treated water during the dye removal and degradation, since those types of biopolymers are effective adsorbents and chelators for semiconductor ions in aqueous solutions [304].…”

During the process and operation of the dyes, the wastes produced were commonly found to contain organic and inorganic impurities leading to risks in the ecosystem and biodiversity with the resultant impact on the environment. Improper effluent disposal in aqueous ecosystems leads to reduction of sunlight penetration which in turn diminishes photosynthetic activity, resulting in acute toxic effects on the aquatic flora/fauna and dissolved oxygen concentration. Recently, photodegradation of various synthetic dyes has been studied in terms of their absorbance and the reduction of oxygen content by changes in the concentration of the dye. The advantages that make photocatalytic techniques superior to traditional methods are the ability to remove contaminates in the range of ppb, no generation of polycyclic compounds, higher speed, and lower cost. Semiconductor metal oxides, typically TiO2, ZnO, SnO, NiO, Cu2O, Fe3O4, and also CdS have been utilized as photocatalyst for their nontoxic nature, high photosensitivity, wide band gap and high stability. Various process parameters like photocatalyst dose, pH and initial dye concentrations have been varied and highlighted. Research focused on surface modification of semiconductors and mixed oxide semiconductors by doping them with noble metals (Pt, Pd, Au, and Ag) and organic matter (C, N, Cl, and F) showed enhanced dye degradation compared to corresponding native semiconductors. This paper reviews recent advances in heterogeneous photocatalytic decolorization for the removal of synthetic dyes from water and wastewater. Thus, the main core highlighted in this paper is the critical selection of semiconductors for photocatalysis based on the chemical, physical, and selective nature of the poisoning dyes.

The present work combines the solar energy with the environmental protection through the membrane selectivity for metallic ions. Firstly, we have elaborated new polymeric membranes for ions separation. The membrane is made up of cellulose acetate (CA) modified by polyelectrolytes (polyethylenimine (PEI), polyvinyl alcohol (PVA) and polyanetholsulfonic acid (PATSA) using glycerol as plasticizer. Different membranes are characterized by Fourier transform infrared spectroscopy (FTIR), X‐Ray diffraction (XRD), thermo‐gravimetric analysis (TGA) and scanning electron microscopy (SEM). In a second part, we have prepared two new photo‐electrodes, crystallizing in the brownmillerites structure: n‐Sr2Fe2O5 and p‐Sr2Co2O5 and their photo‐electrochemical characterizations are undertaken. As application, the transport of Cd2+ using the synthesized membranes coupled with the photo‐electrodes is studied. The photo‐catalytic results indicate that the combined hetero‐system n‐Sr2Fe2O5/p‐Sr2Co2O5 enhances considerably the electrons transfer. The diffusion flux of Cd2+ is considerably enhanced when the electrode is exposed to visible light illumination. The results show that the transport percentages of Cd2+ increases by 40% under solar energy and 25% under a tungsten lamp.
