Trioctylphosphine (TOP)-free synthesis of TiSe2 plates for enhanced photocatalytic degradation performance of Rhodamine B dyes

Photothermal and Enhanced Photocatalytic Therapies Conduce to Synergistic Anticancer Phototherapy with Biodegradable Titanium Diselenide Nanosheets

“…[ 44 ] In another study, Ge and colleagues revealed that TiSe 2 plates show better photocatalytic degradation performance under visible‐light irradiation on Rhodamine B dyes. [ 26 ] After irradiation with visible light, the electrons (e − ) of TiSe 2 are excited from the valence band (VB) to the conduction band (CB), which produce holes (h + ). The produced e − in the CB of TiSe 2 react with dissolved oxygen molecules to form •O 2 − radicals, which oxidate their substrates, while the h + in the VB of TiSe 2 oxidize the substrates directly.…”

“…The photocatalytic capability of TiSe 2 can be described sequentially as follows: TiSe 2 +hv→e − + h + ; H 2 O+h + →•OH; O 2 +e − →O 2 − . [ 26 ] However, under physical conditions, Se plays a crucial role in the active sites of numerous Se‐dependent enzymes such as peroxidase, iodothyronine deiodinase, and glutathione peroxidase (GPx), [ 45 ] which are involved in the production of NO, and regulates their activity. Thus, Se‐based enzymes and organo‐Se species facilitate the endogenous generation of nitric oxide (NO) by catalytically decomposing S‐nitrosothiols (RSNO).…”

“…[20] Very recently, titanium diselenide (TiSe 2 ), a 2D metallic TMDC, has become a research hotspot owing to its good thermoelectric effect and potential applications in PTT and photocatalytic therapy. [21][22][23][24][25][26] TiSe 2 is known only in the 1T polymorph and has a formal valence of 3d° for titanium (Ti). TiSe 2 bulk single crystals contain one titanium (Ti) atom octahedron coordinated by six selenium (Se) atoms, and undergo a phase transition at around 200 K into a charge density wave (CDW) state characterized by the 3D commensurate (2 × 2 × 2) wave vector, [27,28] which alters the energy band gap by introducing transition metals, alkali metals, or organic compounds and shows a different status, that benefit for various potential applications.…”

A study on structural, optical, and electrical characteristics of perovskite CsPbBr3 QD/2D-TiSe2 nanosheet based nanocomposites for optoelectronic applications

“…There is little literature available on the 2D-TMDs NSs mixed with 0-dimensional van der Waals or hybrid nanostructure (perovskite with TMDs NSs). 16,17,32,34–38 The mixed-dimensional van der Waals nanohybride of 2D-TMDs and zero-dimensional perovskite highly promissing candidates for optoelectronic applications. It leads to a reduction in coulombic interaction and enhancement in the transportation of charge carriers of the perovskite layer, which is very useful for enhancing the properties of optoelectronic devices.…”

Sunlight Driven Activated Carbon Modified BiVO4 Photocatalyst for the Degradation of Rhodamine-B

“…In addition, photocatalysis method can lead fast and complete mineralization of contaminants without leaving harmful intermediates due to its enormous oxidising power and non-selective nature of the products produced in the process [3]. TiO2 and ZnO are the common materials used for photocatalytic applications owing to their superior photocatalytic activity [4]. However, the main drawback of these photocatalysts is fascinated only ultraviolet portion of the solar spectrum [5].…”
