Enhanced inactivation of E. coli bacteria using immobilized porous TiO2 photoelectrocatalysis

Visible-light-driven photocatalytic inactivation of E. coli by Ag/AgX-CNTs (X=Cl, Br, I) plasmonic photocatalysts: Bacterial performance and deactivation mechanism

“…Generally, photocatalytic inactivation of E. coli can be divided into three periods [33,34], the initial period is called the "shoulder", where the reactive species (RSs) begin to attack the E. coli, the second period is the main part of photocatalytic process where fast inactivation of bacteria occurs, and the last period is called the "tail", where photocatalytic process is being decelerated. This type of inactivation kinetic process was calculated by the modified Hom model [33].…”

Comparative study on the photoelectrocatalytic inactivation of Escherichia coli K-12 and its mutant Escherichia coli BW25113 using TiO2 nanotubes as a photoanode

“…This limitation can be surpassed by synthesizing new form of efficient photocatalysts or immobilizing TiO 2 catalysts onto conductors that enables the application of electrochemical techniques. Moreover, a photoeletrocatalytic (PEC) system with an external potential bias can provide a superior solution by suppressing the charge recombination [17][18][19][20][21][22][23][24]. Furthermore, compared to the powder forms of TiO 2 , TiO 2 nanotubes can transfer electron more effectively due to their special cannular structure [22,[25][26][27], and subsequently the bactericidal efficiencies in a PEC system can be remarkably enhanced [17,22,23,27].…”

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

“…[3][4][5][6] TiO2-based photocatalysts have been used to inactivate bacteria, viruses, and cancer cells. [7][8][9][10][11][12] However, the wide band gap (3.2 eV) of TiO2 means it can only absorb spectrum in the near-UV region, which limits its, practical applications for photocatalytic inactivation of bacteria. There is thus a need to enhance the absorption capability of bactericidal materials in the visible region.…”
