Hydrothermally stabilized Fe(III) doped titania active under visible light for water splitting reaction

A review on plasmonic metal⿿TiO2 composite for generation, trapping, storing and dynamic vectorial transfer of photogenerated electrons across the Schottky junction in a photocatalytic system

“…Subsequently hydroxyl free radicals can participate in the chemical reaction with CH 3 CH 2 OH [180]. The decomposition of water to H + and hydroxyl radicals is accelerated by the presence of sacrificial agent leading to enhanced hydrogen production [181]. TiO 2 encapsulated Ag nanoparticles supported on porous SiO 2 bead nanospheres were fabricated in the following way: surface protected etching strategy was adopted to synthesize porous SiO 2 core, followed by a calcination process to immobilize Ag nanoparticles on the surface of porous SiO 2 and in turn this was followed by hydrolysis process to coat TiO 2 shell layer, respectively [182].…”

Hydrogen Production over Titania‐Based Photocatalysts

“…1 wt %. [134,146,147] Heavy doping is detrimental to the photoactivity. In order to facilitate the transfer of photoinduced carriers, the metal ions should be injected near the surface.…”

The selective deposition of silver nanoparticles onto {1 0 1} facets of TiO 2 nanocrystals with co-exposed {0 0 1}/{1 0 1} facets, and their enhanced photocatalytic reduction of aqueous nitrate under simulated solar illumination

“…However, most of these processes were not feasible to generate noble metal nanoparticles of small and uniform size and the self-nucleation/crystal growth of noble metals in liquid phase was commonly found, which could be attributed to their relatively fast nucleation/crystal growth rates [40][41][42]. Herein, we reported a newly developed process to selectively deposit silver nanoparticles onto {1 0 1} facets of anatase TiO 2 nanocrystals with co-exposed {0 0 1}/{1 0 1} facets through a modified photo-deposition process.…”
