Photocatalytic indoor/outdoor air treatment and bacterial inactivation on CuxO/TiO2 prepared by HiPIMS on polyester cloth under low intensity visible light

Simultaneous removal of bacteria and volatile organic compounds on Cu2O-NPs decorated TiO2 nanotubes: Competition effect and kinetic studies

“…The photocatalytic experiments were carried out using a 250 mL spherical batch reactor. A Sylvania CF-L 24W/840 source with a spectral emission in visible range (380 -720) nm, which are used in J o u r n a l P r e -p r o o f our previous work [7], could be inserted outside the reactor from above. The variation of the BUT concentration and its oxidation by-products were measured using a gas chromatograph (Clarus GC-500) equipped with a flame ionization detector (FID).…”

“…For this reason, technologies that have the ability to purify air from organic contaminants with efficient and inexpensive processes became the objective of many research groups [5,6]. Thus, several remediation techniques were used to reduce this kind of pollutants using photocatalysts [7,8], non-thermal plasma [9,10], catalytic ozonation [11]. Scientific studies on photocatalysis started about four decades ago and showed that photocatalysis can be an interesting technique for environmental remediation [7,8,12].…”

It is based on the activation of semiconductors by light irradiation making it possible to form active chemical species such as hydroxyl radicals (OH°) leading to the degradation of pollutants [7]. Metal oxide semiconductors received much attention due to their important applications in catalysis, optoelectronics, hydrogen generation and solar cells [13][14][15][16][17][18][19].…”

Hazardous wastes treatment technologies

“…Urea did not significantly influence the BP-3 degradation. Abidi et al (2019) studied the treatment VOCs using low-intensity visible light on photoactive Cu x O/TiO 2 coated on polyester (PES) cloth, Cu x O/TiO 2 -PES, by magnetron sputtering. Degradation of chloroform and butyraldehyde reached 90% and 85%, respectively.…”
