A ternary hybrid CdS/Pt–TiO2 nanotube structure for photoelectrocatalytic bactericidal effects on Escherichia Coli

Photoelectrocatalytic Inactivation of E. coli by ZnSe/CdS Co-sensitized TiO2 Nanotube Array

“…According to the published works 16,31 and the above experimental results, the mechanisms of bactericidal reaction over the CdS/ZnSe/TiO2 system was hypothesized as bellow, and illustrated in Scheme 1.…”

“…To achieve this, much effort has been directed at modifying of TiO2 with nonmetal anions, 13 metallization 14 and narrow-band gap semiconductors. 15 It has been well established in recent research that combining wide-band gap TiO2 with small-band gap nanocrystals, such as CdS, 16 CdSe, 17 ZnSe, 18 and Cu2O 19 can render TiO2 sensitive to visible light.…”

Hierarchical TiO2/CdS “spindle-like” composite with high photodegradation and antibacterial capability under visible light irradiation

“…Nevertheless, wide band gap and fast recombination of photogenerated electron-hole pairs of pure TiO 2 significantly restrict its use under solar light due to only 5% UV light occupied in sunlight can be utilized [6,13]. Therefore, many approaches have been invented to synthesize TiO 2 -based photocatalysts to make use of both UV irradiation (290-400 nm) and visible light (400-700 nm) [13], including dye-sensitized [14,15], metal or nonmetal doped [13,[16][17][18], or coupling TiO 2 with a narrow band gap semiconductor material (Cu 2 O [19], CuS [20], WO 3 [21], CdS [7,[22][23][24][25][26][27][28][29][30][31][32][33][34][35], etc. [36]).…”

Fabrication by AC Deposition and Antimicrobial Properties of Pyramidal-Shaped Cu2O-TiO2 Heterostructures

“…For example, CNT-doped TiNT on glass by dip-coating [11], Ag/TiO 2 composite films [12], CdS/Pt-TiNT [13] and highefficient CdS/TiNT films [14] on the Ti substrate have been reported. However, most of these surfaces showed either low-effectiveness under illumination by bright light or were toxic due to the application of CdS.…”

“…In the past decade, to avoid the cleaning of tested solutions, immobilization of the TiO 2 -based photocatalyst species onto various substrates have been proposed [11][12][13][14]. For example, CNT-doped TiNT on glass by dip-coating [11], Ag/TiO 2 composite films [12], CdS/Pt-TiNT [13] and highefficient CdS/TiNT films [14] on the Ti substrate have been reported.…”
