“…Figure 6 shows the gas emitted and its concentration; herein, no NO x , either NO or NO 2 , was detected under the experimental conditions (Ecom EN2, ecom GmbH, Germany, 1.5 L/min gas sample). However, around 0.3 ppm of O 3 was observed at an applied voltage of 12 kV, which does not signi cantly surpass the limits, considering the possibility of dilution and decomposition to O 2 [39].…”

Multiple Ar jet capillaries (4 jets) were successfully generated by an advanced dielectric barrier discharge reactor. The advanced reactor consisted of two ring-shaped electrodes (thickness of 0.5 mm) covering the 4-bore quartz tubing (bore diameters of 1 mm; outer diameter of 6 mm), and two electrodes had a gap of 6 mm and were isolated by immersing it to liquid dielectric to prevent arcing between two electrodes and high performance of plasma jet. The performance of multiple Ar jet capillaries by the advanced reactor demonstrated less consumption of Ar gas (1-3 L/min) for obtaining total π mm 2 cross-section area of plasma jets conjugated with jet temperatures not over 40°C; the temperature is suitable for implementing plasma to bio-applications. Furthermore, the plasma jet spread when it interreacted with a surface (dielectric materials, skin); consequently, the surface-effected plasma jet up to an area square of 8 mm 2 . Analysis of optical emissions spectra of the multiple Ar jet capillaries indicated that the jet sources consist of reactivated species and proposed that the plasma device has potential for applications in bioapplications and materials treatments.

“…This characteristic of PBF methods signifies a valuable advantage over conventional synthesis, which typically involves coating commercial monoliths with metals such as Fe, Ni, Pd, etc. [ 94–98 ] In this sense, Qinhong et al [ 99 ] printed metallic monoliths through LS to directly serve as catalyst for the conversion of C1 molecules into high value‐added fuels. Fe, Co, and Ni alloys were used to obtain the monoliths with different channels configurations.…”

Additive manufacturing (AM) presents a promising opportunity for the innovative design and production of structured catalytic materials. Given the critical role of catalysts in industrial catalytic processes, AM has the potential to contribute to the development of improved catalysts by reducing activation energy and enhancing selectivity. Conventional synthesis methods limit the choice of structural materials and composition for producing monoliths. Additionally, the deposition of catalytic compounds is also restricted by commonly applied techniques that may require prior coverage or treatments to improve adherence or do not achieve a homogenous coat. Moreover, production is limited to monoliths with straight and parallel channels. However, this format drives to laminar regime flow thus restricting the radial mass and heat transfer. Conversely, AM allows the production of a wider variety of compositions and more complex structures that have proven to rise their effectiveness by increasing reagents‐catalyst interaction, making catalytic processes more cost‐effective. Therefore, in this review an outline of the recent progress of AM methods in the development of monolithic catalysts is presented focusing on the requirements, advantages, and disadvantages of each technique, hence providing a practical overview of their novel opportunities to overcome current limitations in catalyst synthesis.

“…Plasma catalysis in honeycomb reactors is still in its infancy and is commonly used for the decomposition of hazardous contaminants with concentrations less than 1%. For example, Mok et al recently developed a sandwich-type honeycomb reactor combined with axially generated corona discharge, in which >80% of toluene [56] , isopropanol [38] , and ethylene [57] were removed.…”

The plasma catalytic valorization of gases, particularly CH4 and CO2, has gained increasing attention. Value‐added chemicals, such as syngas and ethene, can be formed under mild conditions when temperature‐decoupled plasma activation and multistep feasible catalytic conversion are combined. In this sense, efficient plasma–catalyst interaction is of key importance, for which, however, plasma catalysis, as an emerging technology, is still poorly studied, where new catalyst design and investigation took up the most effort. In this perspective work, the challenging but equally important plasma–catalyst interaction is discussed, comparatively analyzing which type of plasma, catalyst bed, is the most promising. Representative plasma catalytic systems with their characteristic features are summarized, where the intrinsic capability of fluidized‐bed dielectric barrier discharge (FB‐DBD) reactor to maximize the plasma–catalyst interaction is highlighted. Furthermore, ongoing research on FB plasma catalysis is reviewed, based on which the superiority of FB‐DBD to other candidates, especially the most widely used packed‐bed DBD reactor, is critically evaluated. In addition, the perspectives of FB‐DBD, including challenges and development potential, are discussed.
