Fabrication and characterization of Fe 3 O 4 @SiO 2 @TiO 2 @Ho nanostructures as a novel and highly efficient photocatalyst for degradation of organic pollution

Evaluating the efficiency of the GO‐Fe3O4/TiO2 mesoporous photocatalyst for degradation of chlorpyrifos pesticide under visible light irradiation

“…Recently, the photocatalyst process of environmental contaminates has attracted growing attention . Among different approaches, materials based on TiO 2 are the most suitable suppliants for photocatalytic degradation . The high specific surface area is one useful characteristic of the TiO 2 mesoporous photocatalyst supplying more active sites at the surface for photocatalytic reaction.…”

“…[9][10][11][12] Among different approaches, materials based on TiO 2 are the most suitable suppliants for photocatalytic degradation. [13][14][15][16][17][18][19] The high specific surface area is one useful characteristic of the TiO 2 mesoporous photocatalyst supplying more active sites at the surface for photocatalytic reaction. On the other hand, the nanoscale pores of mesoporous photocatalyst help the faster arrival of the photogenerated electron-hole pairs to the surface, and prevent their recombination in bulk.…”

Novel NiFe/Si/Au magnetic nanocatalyst: Biogenic synthesis, efficient and reusable catalyst with enhanced visible light photocatalytic degradation and antibacterial activity

“…Because of the previous investigation, FT‐IR spectra show that NiFe 2 O 4 was successfully synthesized . Figure b shows the small adsorption band around 805 cm −1 and a strong peak around 1109 cm −1 that belong to the symmetric and asymmetric vibrations of Si‐O‐Si . NiFe/Si nanoparticles were correctly synthesized according to previous reports .…”

“…[35] Figure 1b shows the small adsorption band around 805 cm −1 and a strong peak around 1109 cm −1 that belong to the symmetric and asymmetric vibrations of Si-O-Si. [36] NiFe/Si nanoparticles were correctly synthesized according to previous reports. [37] As seen in NiFe/Si/Au FT-IR spectra, gold nanoparticles do not exhibit absorption in the reports.…”
