Ag loaded WO3 nanoplates for efficient photocatalytic degradation of sulfanilamide and their bactericidal effect under visible light irradiation

Two‐dimensional nanomaterials for photocatalytic water disinfection: recent progress and future challenges

“…In this case, morphology control and surface doping are commonly used to address the problem. Ag particles have been used as a dopant to modify the physicochemical properties of 2D structures, because of the perfect conductivity and SPR effect . For example, in a study conducted by Yan's group, a small quantity of Ag nanoparticles (1.6 wt%) were loaded on the lateral surface of WO 3 plates through photo‐reduction .…”

The Effect of Gamma (γ) Irradiation to inactivate Escherichia coli in Contaminated water

“…These days radiation method is used as portable method, which does not cause ionization of water and also any changes in physical and chemical properties of water. One of the main advantages of Gamma radiation consists of the fact that since irradiation is a physical process, no chemicals have to be added (Vilela, Oliveira, Vicentini, Casagrande, Verri, Cunha & Fonseca 2016;Zevallos-Concha, Nunez, Gasco, Vasquez, Quispe & Gonzales 2016;Zhu, Liu, Yu, Zhou & Yan 2016).…”

Detailed Spectroscopic and Structural Analysis of TiO2/WO3 Composite Semiconductors

“…e final goal of these composite systems is either to apply them as a sensor or as a photocatalyst, or even both simultaneously. Photocatalytic efficiency of WO 3 semiconductor can be enhanced if noble metals are added, WO 3 /Au, WO 3 /Ag, or WO 3 /Pt composite systems being related to show an improved photocatalytic efficiency towards the removal of organic pollutants in comparison with commercial TiO 2 (Evonik Aeroxide P25) [26][27][28]. e photocatalytic activity of ternary composites based on WO 3 , commercial TiO 2 , and noble metals (WO 3 /TiO 2 /noble metals) was also intensively studied [29][30][31].…”
