Nonthermal plasma (NTP) technology, as an emerging and promising
technology, has been exploited for a variety of applications, including
material synthesis, surface modification, and the removal of pollutants
from air and water. In line with these high-value achievements, a
wide range of chemical reactions have been activated by NTP due to
its high stability and efficiency. Nevertheless, NTP can be considered
an alternative approach for implementing reactions, particularly those
that suffer from harsh conditions in conventional techniques. Moreover,
the combination of NTP with various catalysts in some chemical reactions
has demonstrated significant enhancement in both the conversion of
the reactant and the selectivity of the desired product. This review
provides an overview of the accomplishment of various chemical reactions,
such as oxidation, reduction, copolymerization and polymerization,
elimination, addition, isomerization, and rearrangement reactions,
in NTP systems. Additionally, it explores the possible mechanisms
underlying these reactions by examining the species generated in the
plasma atmosphere.
