“…[127] Additionally, it has been proved by Moon et al that B 2 O 3 can suppress the rapid thermal back reaction. [128] Physically separating the H 2 and O 2 evolution sites is a thorough way of avoiding the back reaction of H 2 and O 2 . This was achieved by combining two photocatalytic reactions on suspended TiO 2 powders using a two-compartment cell, which was equipped with platinum electrodes and a cation-exchange membrane.…”

Because of their relatively high efficiency, high photostability, abundance, low cost, and nontoxic qualities, titania-based photocatalysts are still the most extensively studied materials for the photocatalytic production of hydrogen from water. The effects of the chemical and physical properties of titania, including crystal phase, crystallinity, particle size, and surface area, on its photoactivity towards hydrogen generation have been identified by various investigations. The high overpotential for hydrogen generation, rapid recombination of photogenerated electrons and holes, rapid reverse reaction of molecular hydrogen and oxygen, and inability to absorb visible light are considered the most important factors that restrict the photoactivity of titania, and strategies to overcome these barriers have been developed. These issues and strategies are carefully reviewed and summarized in this Minireview. We aim to provide a critical, up-to-date overview of the development of titania-based photocatalysts for hydrogen production, as well as a comprehensive background source and guide for future research.

“…Moon et al [23] have reported on titanium oxide modified with boron (B 2 O 3 /TiO 2 ) prepared by a sol-gel method which exhibited remarkable activity for the photocatalytic splitting reaction of water. Boron oxides are known to strongly interact with water molecules and become moist easily in air [23], a great advantage in the efficient splitting of water.…”

“…Boron oxides are known to strongly interact with water molecules and become moist easily in air [23], a great advantage in the efficient splitting of water. In fact, Pt/ TiO 2 modified with boron oxide (Pt-B 2 O 3 /TiO 2 ) exhibited a high photocatalytic activity for the splitting of water even under irradiation by an inner irradiation system.…”

“…This possibility has been reported, however, in just few studies. [16][17][18] To the best of our knowledge, a detailed study regarding the role of the B 2 O 3 -TiO 2 interfaces on the superior photocatalytic activity of this type of material is unprecedented.…”

An investigation on unusual interface properties of unprecedented ternary composites, formed by the inclusion of assorted proportions of B 2 O 3 into TiO 2 /SiO 2 structure, is conducted herein. The influences of B 2 O 3 content and calcination temperature were evaluated. The precursor TiO 2 /SiO 2 material was synthesized via a simple sol-gel procedure that was followed by B 2 O 3 inclusion via maceration and calcination. The materials were fully characterized and their photocatalytic performance to degrade the Indigo Carmine dye investigated. The material prepared with a B/Ti molar ratio of 1 and at calcination temperature of 350 °C (B 1-350 ) showed the best performance, with a superior photocatalytic activity than that of commercial TiO 2 . The presence of B 2 O 3 -TiO 2 -SiO 2 interfaces in the structure of such material was of critical importance in producing a material with these attractive features. Finally, high resolution mass spectrometry monitoring allowed for the characterization of the main degradation products formed under these conditions.
