Tuning the properties of a black TiO2-Ag visible light photocatalyst produced by a rapid one-pot chemical reduction

Mixed‐Phase 2D‐MoS2 as an Effective Photocatalyst for Selective Aerobic Oxidative Coupling of Amines under Visible‐Light Irradiation

“…[11] However,w hen unmodified, these semiconductingm aterials all suffer from low photocatalytic activity due to rapid recombination of the photoexcited electron-hole pair.T oo vercome these problemsg eneral strategiest os eparate charges have been introduced and this was accomplished using heterojunctions( metal-semiconductor or semiconductorsemiconductor) with appropriate band-edge alignments to ushere lectrona nd holes in opposite directions. Successful material combinationsi nclude hybrid semiconducting junctions (e.g.,T iO 2 -CdS), [12] and semiconductor-metal junctions such as TiO 2 -Au, [13] TiO 2 -Ag [14] and TiO 2 -SWCNT [15] (single-walled carbon nanotube), etc. have been reported in many photocatalytic applications.…”

Black carbon-doped TiO2 films: Synthesis, characterization and photocatalysis

“…which reduce the photocatalytic activity [27]. On the other hand, a lot of researchers showed that black colour TiO 2 demonstrates promising features of wide optical absorption as well as possibility to decompose various pollutants under visible light irradiation [28][29][30][31].…”

Synthesis of a 2D Cu@TiO2 composite via the design of a 1D Cu-based coordination polymer precursor for efficient and selective photodegradation of dyes

“…18,19 Metallic elements can induce a suitable bandgap shi and promote recombination, as a result of minimizing the photocatalysis capability in combination with thermal instability. 20,21 Among them, noble metal doping for TiO 2 is generally considered to be a good choice for enhancing the photocatalytic activity of TiO 2 . 20,21 However, the reaction setup is costly and the method is hampered by several other drawbacks as noble metals like Au and Ag are quite toxic in nature.…”
