Photocatalytic performance of TiO2@SiO2 nanocomposites for the treatment of different organic dyes

The controlled synthesis and DFT investigation of novel (0D)–(3D) ZnS/SiO2 heterostructures for photocatalytic applications

“…Several strategies have been adopted to overcome these liabilities, such as metal doping, non-metal doping, co-doping using narrow-bandgap semiconductors or other metal oxides, dye sensitization, and formation of composites using 2D materials such as graphene and hexagonal boron nitride. [17][18][19][20] The main challenge in this context is selecting a material with high semiconducting performance, high stability, recyclability, and biocompatibility. ZnS is an essential II-V group semiconductor that has intrigued scholars around the world owing to its numerous morphologies at the nanoscale, superior mechanical and physical properties, non-toxicity, and excellent photocatalytic properties.…”

Novel TiO2/GO/CuFe2O4 nanocomposite: a magnetic, reusable and visible-light-driven photocatalyst for efficient photocatalytic removal of chlorinated pesticides from wastewater

“…[9][10][11][12] Titanium dioxide (TiO 2 ) is a much used photocatalyst because it is non-toxic, chemically and photochemically stable, readily available, and easy to synthesize. 13,14 However, TiO 2 has two major demerits: it possesses a wide bandgap energy value of 3.2 eV for pure anatase, which limits its activity under UV irradiation, and it exhibits rapid electron-hole recombination, which decreases its photocatalytic performance. 15,16 Various strategies, including doping by metallic/nonmetallic species, dye sensitization, as well as coupling with narrow bandgap semiconductors, have been developed to expand its photoresponse into the visible light region, decrease electron-hole pair recombination and increase its activity for the removal of toxic pollutants from industrial effluents.…”

Acceleration of ammonium phosphate hydrolysis using TiO2 microspheres as a catalyst for hydrogen production

“…22,23 Titanium dioxide microsphere materials can be prepared by different methods, including hydrothermal, sacricial templating, precipitation, sol-gel, gas bubbling and microemulsion. [24][25][26][27][28][29] Further, it is noticed that the presence of pores in titanium dioxide spherical particles enables the increase in their reaction rate with other materials. 30 Therefore, we used these spherical porous materials to accelerate the process of ammonium phosphate hydrolysis.…”
