Hydrogen Production Using TiO2-Based Photocatalysts: A Comprehensive Review

“…Titanium­(IV) oxide naturally exists in two phases, namely, rutile and anatase, with a tetrahedral shape and simple synthesis . Meanwhile, the other third phase is called brookite, which can be synthesized in laboratories and is rhombic in shape.…”

“…In recent years, many different metal-oxide-based semiconductors as catalysts have been reported . Some metal oxides such as SrTiO 3 , TiO 2 , BaTi 4 O 9, ZrO 2 , and CeO 2 have a reasonable ability to split water H 2 and O 2 under visible and ultraviolet light radiation. , From all of these, TiO 2 is favorable due to having a band gap of 3.2 eV in the anatase phase, high stability in the form of an aqueous solution under UV radiation, high reducing and oxidizing power, nontoxicity, and cost effectiveness. , …”

“…13,14 From all of these, TiO 2 is favorable due to having a band gap of 3.2 eV in the anatase phase, high stability in the form of an aqueous solution under UV radiation, high reducing and oxidizing power, nontoxicity, and cost effectiveness. 3,5 1.2. Limitations.…”

“…Alternatively, for hydrogen production, photocatalytic water splitting using TiO 2 as a photocatalyst through solar energy is very promising. This way of producing hydrogen was very clean, low-cost, and environmentally friendly. − …”

“…Titanium(IV) oxide naturally exists in two phases, namely, rutile and anatase, with a tetrahedral shape and simple synthesis. 5 Meanwhile, the other third phase is called brookite, which can be synthesized in laboratories and is rhombic in shape. The photocatalytic activity of TiO 2 such as anatase and rutile is influenced by crystal structure, surface area, surface hydroxyl density, porosity, and size 4 , 5 , 9 because all these factors affect the production of electrons and holes.…”
