“…28 It was suggested that oxygen in the products originated from the silica surface. Irradiation of benzene-d6 gave dideuteroketene (2-d2) and monodeuteroketenes (2-d1), in which the protium arose from pentadeuterobenzene in the benzene sample.…”

Recent advances in ketene chemistry are reviewed, including synthetic, mechanistic, and computational studies. Topics include ketene structure determination by experimental and theoretical methods, computational studies of bonding in ketenes, spectroscopic properties of ketenes, preparation and formation of ketenes including photochemical and thermal methods, the discovery and observation of ketenes in space, and ketene reactions. The last category includes decarbonylation, cycloadditions with carbon-carbon, carbon-nitrogen, and carbon-oxygen multiple bonds, addition of oxygen, nitrogen, and carbon nucleophiles, and electrophilic additions.

“…They noted the formation of acetylene, butadiene, fulvene, benzopentene, methane, ethylene, phenyl, and butadiyne groups as well as a number of intermediate oxidation products. They were hydroperoxy radical, propylene‐1,3‐dione, vinyl ketone, alkenyl ketone, formyl, formaldehyde, and formyl [36] . The elimination of VOCs by plasma discharge is evidently a challenging process.…”

[36] The elimination of VOCs by plasma discharge is evidently a challenging process. Consequently, the primary objectives of this technology are to reduce the production of secondary pollutants, such as O 3 and NO x , during the breakdown of VOCs in NTP, and to enhance energy efficiency.…”

Volatile organic compounds (VOCs) emissions are a factor in a number of environmental issues. To reduce the associated negative consequences, it is crucial to develop efficient VOCs removal systems. Non‐thermal plasma (NTP) co‐catalytic technology has become a popular research topic in this field as a result of its ability to reduce the activation energy of the reaction while simultaneously improving product selectivity. Despite the huge number of studies synthesising the use of metals and their oxide catalysts in the degradation of VOCs, metal‐organic frameworks (MOFs) and MOF derivatives are the subject of comparatively few studies in this area. This paper reviews the basic principles and technological progress of NTP co‐catalytic VOCs degradation, with a focus on the use of MOFs and their derivatives in plasma VOCs degradation, as well as the use of other non‐metallic carbon materials in plasma VOCs degradation. It highlights the potential future development direction of NTP catalytic synergistic treatment of VOCs by focusing on the optimization of catalytic synergism on the treatment impact. In the end, the challenges faced, the prospects, and our personal perspective on future research directions are also estimated and elucidated.

“…2 and S4, lending support to their identification as chain oxides. Further, ketene has been observed in a matrix FTIR study of products of benzene transformations in a pulsed glow discharge at low pressure in highly diluted mixtures of benzene with argon in the presence of small amounts of oxygen [54]. As an interesting aside, the observation of the production of ketene and C 5 O 2 in a non-thermal plasma catalysed by common elements has direct relevance to the origin of life: e.g.…”

In situ Fourier Transform Infra Red spectroscopy was employed to study the plasma glow region of a non-thermal plasma between two Macor dielectrics and fed with CO 2 , CH 4 and N 2 . CO, HCN and formaldehyde were produced and rapidly attained steadystate conditions. In addition, the chain oxides C 5 O 2 and ketene were observed (the first time such species have been seen in the dry reforming of methane) and a liquid film was produced comprising multiple components, one of which was acetamide. The data were interpreted in terms of catalysis by the Macor dielectric and a wholly novel, multizone model in which the liquid film plays a direct and important role. The data obtained in the plasma experiments were compared to an analogous, thermal experiment. Importantly, the results from this work could have major implications across the fields of catalysis, synthesis and origin-of-life chemistry.
