Antibacterial activity of Clinoptilolite/TiO 2 /ZnO photocatalyst against Escherichia coli and Staphylococcus aureus in water resources

“…Bacteria can be eliminated using photocatalytic processes using conventional photocatalysts, such as TiO 2 [10][11][12][13] , ZnO [14][15][16] , CuO 17,18 , and Ag [19][20][21] . There are two bands in the mentioned photocatalysts:…”

CuO/TiO2 Nanobelt with Oxygen Vacancies for Visible-Light-Driven Photocatalytic Bacterial Inactivation

“…), have been developed and widely applied in air purification, wastewater treatment, and bacterial inactivation. − Among these metal oxides, TiO 2 is the photocatalyst with the most potential because of its chemical stability, low toxicity, lack of skin irritation, and broad-spectrum antibacterial properties. − However, the wide-band-gap nature of TiO 2 (3.0–3.2 eV) has limited its use to only UV-light absorption. Incorporating transition metals with narrow-band-gap energy values to construct TiO 2 nanomaterials is a simple and efficient strategy for improving the light absorption efficiency . In addition, the construction of defect engineering, especially oxygen vacancies (O v ), is a feasible approach to improving the photocatalytic properties of nanomaterials.…”

“…Incorporating transition metals with narrow-bandgap energy values to construct TiO 2 nanomaterials is a simple and efficient strategy for improving the light absorption efficiency. 22 In addition, the construction of defect engineering, especially oxygen vacancies (O v ), is a feasible approach to improving the photocatalytic properties of nanomaterials. The band gap can decrease by the introduction of a defect level, which significantly enhances the photocatalytic activity, thus further producing more higher reactive oxygen species (ROS).…”

SnS2 Nanoparticles and Thin Film for Application as an Adsorbent and Photovoltaic Buffer

“…Indeed, most dyes are chemically stable for their intended purposes and are challenging to break down biologically [17]. As a result, photocatalysis [18,19], chemical oxidation [20], and adsorption [21] are the primary methods for removing dyes from aqueous solutions. Adsorption is viable for removing hazardous dyes from aqueous solutions as it is simple to conduct, inexpensive, environmentally benign, efficient, and requires little energy [22].…”
