Synthesis of an efficient, and recyclable mesoporous BiVO4/TiO2 direct Z-scheme heterojunction by sonochemical route for photocatalytic hydrogen production and photodegradation of rhodamine B dye in the visible region

Photocatalytic Applications of Titanium Dioxide (TiO2)

“…The formation of heterojunction of titanium dioxide with other semiconductor metals oxide is also an attempt to improve the photocatalytic performance by separation of positive holes and electrons and narrowing the band gap. The synthesis of heterojunction or composite of titanium dioxide with other semiconductors has gained much attention [53]. The formation of heterojunction shifts the absorption capacity of titanium dioxide towards the visible wavelength side and thus improves the catalytic performance.…”

“…Similarly, heterojunctions of titanium dioxide with other semiconductors have also been reported. For example, Abd-Rabboh and his co-workers [53] have reported the synthesis of BiVO 4 -TiO 2 heterojunction as an effective photocatalyst for photodegradation of rhodamine B dye. They reported the heterojunction between BiVO 4 and TiO 2 for the production of hydrogen gas and photo degradation of rhodamine B dye.…”

Preparation of BiVO4/RGO‐TNT Nanomaterials for Efficient and Recyclable Photocatalysis of Imidacloprid Insecticide

“…TiO 2 is a kind of widely used photocatalyst which can degrade various organic pollutants efficiently, due to its good stability, low price and high photocatalytic ability. [48][49] Reduced graphene oxide (RGO) also attracts immense attention due to its high activity and large surface area with excellent electron mobility and thermal stability, thus always is acted as electron acceptor in photocatalytic reactions to increase the separation rate of photogenerated electrons and holes. It has been already proven that introducing RGO into TiO 2 can effectively promote the transfer of photo-induced electron-hole pairs to generate more hydroxyl radicals and superoxide anions.…”

Synthesis and Photocatalytic Degradation of Water to Produce Hydrogen from Novel Cerium Dioxide and Silver-Doped Cerium Dioxide Fiber Membranes by the Electrospinning Method

“…As a secondary energy source, hydrogen energy has the advantages of being abundant, economical, clean, efficient, storable, and transportable, and is generally regarded as one of the most ideal pollution-free green energy sources in the 21st century (Prekob et al, 2020). At present, one of the main means of hydrogen production is photocatalytic decomposition of water to produce hydrogen, and the key of this is to choose a good photocatalyst (Bashiri et al, 2020;Abd-Rabboh et al, 2021;Hamdy et al, 2021). Therefore, it is interesting to develop new photocatalysts to construct specific defect structures and to study their photocatalytic activity.…”

“…As the one of the most abundant rare elements in nature, cerium has a unique 4f electronic structure which makes its compounds widely used in optical, electrical, and magnetic fields (Rajesh et al, 2020;Abd-Rabboh et al, 2021;Wang et al, 2021a;Wang et al, 2021b;Syed et al, 2021). Cerium dioxide is a promising semiconductor photocatalyst, because it has the properties of n-type semiconductors such as good light-resistant corrosivity and excellent storage and release of oxygen, and its unique Ce 3+ /Ce 4+ valence activity makes it highly oxidative and gives it a reducing ability (Mishra et al, 2018;Wen et al, 2018;Xing et al, 2020;Wang et al, 2021c;Wang et al, 2021d).…”
