“…Zn-doped SBA-15 mesoporous silica was found also to be a good support for CdS photocatalysts because of its particle sieving ability to immobilize the sizequantized CdS nanoparticles selectively and to archive a well-defined nanostructure [25]. Photocatalytic generation of hydrogen on Zr-MCM-41 [26], CdS/Al-HMS [27] and Fe-HMS [28] was also reported.…”

“…Conversely, among the AOPs is a photo‐catalysis process, heterogeneous and homogeneous photo‐catalysis which is based on the irradiation and on the catalyst with a semi‐conductor property . An efficiency and successful application of photo‐catalysis depend on the interaction between pollutant and catalyst at the interface semiconductor/electrolyte and also on the irradiation source.…”

The present study involves the degradation of ibuprofen (IBP) anti‐inflammatory drug used in the pharmaceutical sector by photo‐catalysis, photolysis and photo‐Fenton processes. IBP degradation through these processes was investigated under UV irradiation used a catalyst based on iron incorporated in mesoporous silica framework (JUL‐15). The catalyst was characterized by XRD, BET, FTIR, diffuse reflectance UV‐Vis, SEM/EDX, and electrical conductivity. The photo‐catalytic properties of this material were evaluated via IBP degradation by varying different parameters as the pH levels, the concentration of IBP and the catalyst amount. The IBP abatement was monitored by UV‐visible spectrophotometry and HPLC. The characterization results indicated that, the material has a small particles size and a specific surface area above 109 m2 g−1. The optical band gap (∼ 1.4 eV) obtained from Kubelka‐Munk equation was well suited in the UV region. A higher degradation was observed with an initial catalyst concentration of 0.25 g/L. Moreover, the catalyst demonstrates significant photo‐degradation after 210 min under UV light (lamp's wavelength of 254 nm). © 2017 American Institute of Chemical Engineers Environ Prog, 37: 738–745, 2018

“…In our previous paper, we reported a study of iron particles prepared by a microwave–hydrothermal method. The results revealed that the presence of iron nanoparticles enhanced visible light irradiation properties via water reduction []. However, nanoparticles and bulk sample comparison showed a large amount of H 2 using a water splitting process .…”

The magnesium ferrite derived from layered double hydroxides (molar ratio Mg/Fe = 2), synthesized by coprecipitation method is found to be an active photocatalyst for hydrogen production from water under visible light. The structural, morphological, and optical properties of the material are characterized by powder X-ray diffraction, scanning electron microscopy, and Fourier transform infrared and UV-Vis diffuse reflectance spectroscopy. The results indicated that the material has small particles with a diameter of~1.8 nm and a specific surface area above 60 m 2 g À1 . The optical properties revealed semiconducting properties with band gap energy of 1.74 eV, showing an efficient visible light absorption. The cyclic voltammetry indicated that the photoelectrochemical response of the material is characterized by type p conductivity. Furthermore, the solid exhibited a high photoactivity toward the reduction of water, which is attributed to the efficient separation and transportation of the photogenerated charge carriers. Under visible light, the best performance is achieved at pH 10 with a hydrogen liberation amount and quantum efficiency of 223 mol and 0.5%, respectively, after 1 h of irradiation.
