“…The use of hybrid systems in automotive applications for onboard fuel conversion still faces technological barriers due to cost, size, weight, and complexity. So, in this scenario, the use of non-thermal plasma as a pretreatment or preparation technique for catalyst production, as shown in Figure 2A, more specifically supported metal catalysts, has been more intensively investigated (Lee et al, 2009;Rahemi et al, 2013a,b,c;Wang et al, 2018b). The development of catalysts with higher catalytic activity, selectivity, stability, and resistance to deactivation and sintering should consider the appropriate metal (active phase), support, promoter (if necessary), structure, and, consequently, preparation method (Jang et al, 2019).…”

“…Reducing the size of metallic particles present on the surface also favors the occurrence of more intense interactions between the metal and the support, contributing to greater sintering and coke deposition resistance during reactions. Therefore, supported metal catalysts prepared through plasmaassisted processes may present greater stability and durability even under more severe reaction conditions (Lee et al, 2009;Rahemi et al, 2013b;Wang et al, 2013). In the following sections, results reported in the literature about the pros and cons of introducing plasma techniques in supported metal catalyst preparation will be presented and discussed.…”

The growing demand for energy worldwide and the extensive use of fossil fuels have resulted in severe environmental problems such as air pollution and the accumulation of greenhouse gases in the atmosphere. In this scenario, both new energy sources and more efficient energy conversion processes have been deeply studied. Heterogeneous catalysis is currently widely used for hydrogen production due to its higher selectivity and conversion compared to other processes. Although the use of catalysts is fundamental for green chemistry, their production through traditional methods is less environmentally friendly. Nonetheless, in order to obtain more efficient supported metal catalysts, interest in using non-thermal plasma as a pretreatment or synthesis technique is increasing. Thus, the present article aims at summarizing and briefly discussing the relevant research results on this subject, elucidating the advantages and disadvantages of using nonthermal plasmas in the preparation of supported metal catalysts. Aspects such as morphology, the chemical composition of the catalytic surface, crystallographic phases, average size and dispersion of crystallites, specific surface area, and metal-support interaction have been analyzed. The use of plasma-assisted techniques contributes to the synthesis of supported metal catalysts with smaller, more dispersed, and strongly bonded active particles, resulting in higher catalytic activity, conversion rate, selectivity, and durability. In addition, plasma allows the synthesis of supported metal catalysts to be enhanced by reducing the process time, the use of hazardous substances, and the temperature required.

“…Although there are several studies in literature about simultaneous use of plasma and catalysis (also known as plasma assisted catalysis or simply PAC) to convert fossil fuels into H 2 , few have been studied about the effect of plasma as a synthesis process of catalysts, more specifically to obtain supported metal catalysts. Based on previous studies about plasma treatment of supported catalyst [15][16][17][18] , it is believed that plasma-assisted processes can be used as standard method for their production in a simple and effective way. Among them, sputtering stands out as an interesting technique to be used.…”

The combination of plasma processes and heterogeneous catalysis for hydrogen production (H 2) is an innovative green technology, resulting in synergic effects and unique fuel conversion outcomes, such as greater selectivity and lower activation temperature. The present study aims at investigating the feasibility of using plasmaassisted processes as standard technique to produce supported metals catalysts. For this, owing to the higher cost of nickel and cobalt (traditional catalytic metals) compared to other more common metals, iron was selected as testing material. Fe/Al 2 O 3 supported catalysts can be applied in dry reforming of methane (DRM), the main component of natural gas.
