Synergism between non-thermal plasma and photocatalysis: Implicationsin the post discharge of ozone at a pilot scale in a catalytic fixed-bed reactor

Abstract

HIGHLIGHTS  C4H8O removal using (UV-TiO2/plasma) + catalytic-bed system is studied.  Specific catalysts are tested for C4H8O/O3 removal at pilot scale.  Impacts of operating parameters on process performance are defined.  Highly efficient synergetic association was obtained.  Better performance in mineralization rate via ozone valorization.

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

“…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].…”

Aldehydes gas ozonation monitoring: Interest of SIFT/MS versus GC/FID

“…Some GC material could act as a catalyst, as it was already observed for metal oxides, zeolites and carbon-based materials which can enhance the ozone-oxidation of VOCs (Brodu et al, 2012;Kastner et al, 2008;Masuda et al, 2001;Oyama, 2000). On the surface of these catalysts, the ozone reacts with the active sites (Lewis acid site) to form secondary oxidizing agents (atomic oxygen, peroxide ions, hydroxyl radicals), which subsequently react with the pollutants (Abou Saoud et al, 2019;Brodu et al, 2018;Wang et al, 2018).…”

Efficient Degradation of Toluene over MnO2/TiO2 Nanobelts under Vacuum Ultraviolet Irradiation

“…Volatile organic compounds (VOCs) contribute to the formation of pollutants such as photochemical smog and ozone in the atmosphere . In addition, long-term exposure to VOCs can pose a threat to human health, including headaches, damage to the respiratory system and nervous system, , and in severe cases, increase the risk of cancer . Therefore, it is very important to take effective measures to remove VOCs in the environment and minimize the threats to environment and human health.…”
