Kinetic study of ketones photocatalytic oxidation in gas phase using TiO2-containing paper: effect of water vapor

Photocatalytic paper using zinc oxide nanorods

“…Subsequently, a few publications and patents describing photocatalytic paper have appeared in the literature [11][12][13]. The majority of available reports on photocatalytic paper mention TiO 2 as a photocatalyst, which absorbs light mostly in the ultraviolet region of the electromagnetic spectrum [7].…”

Photocatalytic oxidation of methyl ethyl ketones over sol–gel mesoporous and meso-structured TiO2 films obtained by EISA method

“…Indoor pollution is of increasing concern in urban societies since much people spend most of their time (between 70 and 90%) into closed areas (building and transports) [1][2][3][4][5][6]. Indoor air quality (IAQ) is affected by many factors among which the presence of volatile organic compounds (VOCs) are well known for their toxic effects on human health [7][8][9].…”

“…There is some literature dealing with the photocatalytic oxidation of ketones (acetone, methyl ethyl ketone (MEK), methyl isobutyl ketone (MIBK) or methyl isopropyl ketone (MIPK)) using supported-TiO 2 catalysts, and most of these papers focuses on the influence of water vapour on the degradation of these compounds [3,33]. However, the effect of the structure and characteristics of the TiO 2 catalyst have been rarely reported [34,35].…”

Determination of Linear Short Chain Aliphatic Aldehyde and Ketone Vapors in Air Using a Polystyrene-coated Quartz Crystal Nanobalance Sensor

“…They are indoor and outdoor chemical pollutants of particular interest due to their potential impact on human health, and most of them are classified in the first group of hazardous materials (human carcinogens) by the International Agency for Research on Cancer because of their carcinogenicity (IARC, 2004). [23][24][25] Aldehyde and ketone vapors are emitted into the atmosphere from anthropogenic sources, such as cigarette smoking, building materials, hardwood, plywood, laminate floorings, adhesives, paints, industrial solvents and various industries. 23,24 In addition to direct emissions, it was also observed that these compounds can be generated through indoor ozone chemistry, or may also react with NOX in the atmosphere to form even more toxic photochemical smog and ozone.…”

[26][27][28] The aim of this work is to develop a polymer modified QCN sensor for the detection and determination of aldehyde and ketone vapors in the atmosphere.…”
