“…The initial reaction rate W 1 (in 1 min after the start of reaction) was determined from the time dependence of the pressure of the formed hydrogen [5]. The dependence of W 1 on the initial pressure of isopropanol Р 0 was determined at each constant temperature from the indicated range.…”

The effect of the treatment of the 5 wt % Cu/SiO 2 (I) and (5 wt % Cu + 0.5 wt % Ce)/SiO 2 (II) catalysts with glow discharge plasma in O 2 , H 2 , and Ar on their structural characteristics was studied by X ray phase analysis; the influence of cerium additions and plasmochemical treatments on the catalyst activity in isopropanol dehydrogenation was also investigated. Under the plasmochemical treatment, the diameters of Cu particles in catalyst I nearly doubled and microstresses in the metal particles also changed. Catalyst II was X ray amorphous both before and after plasmochemical treatments. The activity of I after plasmochemical treatment increased because of the increase in the number of centers and changes in their composition. Growth of the activity of I compared with the activity of II was explained by the formation of new catalytic centers due to positive charging of the Ce +α adatom on the surface of the copper particle.

“…Besides the particular processes described above, there are other notable reactions and applications in which the role of the plasma type in changing catalytic parameters especially the activity is investigated. Hydrogenation/dehydrogenation of isopropanol and cyclohexane, higher alcohols synthesis, hydrogenation of acetylene, photocatalytic reactions, methane combustion, and plasma‐treated catalyst execution in proton exchange membrane fuel cell are the examples of such processes.…”

Heterogeneous catalysis is of great importance in chemical industries. Hence, various approaches are studied to improve catalyst characteristics with the purpose of promoting catalytic reactions. Among them, non‐thermal plasma treatment has attracted more attention due to its low temperature operation, simplicity, and shorter processing time. An extensive review has been performed for better understanding of various aspects of this technique. Unanimously, it is reported that plasma method leads to higher conversion, lower temperature activity and better coke suppression. In light of the investigated literature, application of plasma seems to have potential of starting a revolution in chemical processes. However, it necessitates more works to promote this technology toward industrial application.
