“…While incorporation of AgX in high specific surface area substrate is another promising strategy in photocatalytic activity promotion, especially in wastewater treatment [322][323][324][325][326]. With the substrates as dispersing templates, homogeneous and uniform semiconductor crystal morphology could be formed, which in turn can enhance their photocatalytic performance [327][328][329][330][331][332][333][334]. The graphene sheets with high optical transmittance, large 2D specific surface area, unique electronic properties and locally conjugated aromatic system has regarded as one kind of ideal substrate candidates for photocatalytic deposition.…”

The silver halides and their corresponding composites would constitute remarkable photocatalytic systems not only in energy production but also in environmental remediation. The major advantage in these silver halides system is that plasma metal Ag 0 species would be spontaneously generated by silver halides under light irradiation, which play dual roles of expanding light absorption range and charge carriers separation. In this tutorial review, the origin and development of silver halides, synthesis methods, construction of composite structures with other materials, photocatalytic applications, and various and controversial mechanisms are all exhaustively described.

“…Properties such as high surface area, individual micro-pores, owing Lewis acid sites, a variety of channels and high resistance make zeolites as very useful materials in industrial applications and academic research. In addition antibacterial activity of zeolite-based compounds has recently been reported [24][25][26][27][28][29][30]. Moreover, their inorganic framework preserves them from photo-decay.…”

“…The absorption of the dyes was determined by UV-vis spectrophotometer (GBC Cintra40) at k ¼ 574 and 552 nm, which are the k max values of AB92 and RB solutions, respectively. The antibacterial experiments were performed under the operational conditions which were explained elsewhere (Padervand et al, 2012;Padervand et al, 2013).…”

Ag[1-butyl 3-methyl imidazolium]Br nanospheres were prepared by a coprecipitation method at ambient temperature. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), diffusion reflectance spectra (DRS), the BrunauerÀEmmettÀTeller (BET) nitrogen adsorption-desorption isotherms, and Fourier transform infrared spectroscopy (FT-IR) analysis methods. The photocatalytic properties were evaluated by degradation of acid blue 92 (AB92) and rhodamine B (RB) dye solutions under visible light and the obtained results were discussed. According to the recycling experiments, the samples could efficiently decrease the concentration of the pollutant after four times of repeated using. To assure the practical capacity, photodegradation of a real wastewater produced in the textile industry was studied under the same conditions and the results indicated that the absorption in all wavelengths reduced impressively by the photocatalytic treatment. Furthermore, the antimicrobrial activity was investigated by photoinactivation of S. aureus bacteria in the visible light and the results implied that the prepared samples were able to prevent the growth of bacteria colonies after the reaction time.
