“…The electrons and strong electric field in cold plasma are helpful for enhancing metal‐support interaction, which have been observed for both LP cold plasma and AP cold plasma . Many research studies indicated that enhanced metal‐support interaction can prohibit the sintering of metal NPs in long‐term and (or) high‐temperature process and decrease the leaching of metal species in liquid phase reaction . Therefore, the activity and stability of the supported metal catalysts can be improved.…”

Supported metal catalysts are of great importance in energy and environmental applications. Atmospheric-pressure (AP) cold plasma, generally generated by dielectric barrier discharge and cold plasma jet, has been proved to be a fast, facile, and energy efficient method for fabricating supported metal catalysts. In this review, the recent progress, challenges, and perspectives of AP cold plasma for synthesizing supported metal catalysts are discussed. Focus is placed on recent work demonstrating the discharge types of AP cold plasma, and the characteristics of the synthesized supported metal catalysts. The reduction mechanism of AP cold plasma is also discussed in light of several possible mechanisms that have been proposed in previous work.

“…25 Nevertheless, nickel-catalysts are susceptible to deactivation by sintering and carbon deposition. 30 Recently, Yang et al 31 in their extensive review reiterate the importance of using perovskite-type oxides as precursors for preparing supported metal catalyst. 29 Till now, supports such as Al 2 O 3 , CeO 2 , La 2 O 3 , ZrO 2 , SiO 2 , SBA-15, and perovskite LaFeO 3 have been used for the synthesis of Ni catalysts employed for SMR.…”

Summary Over the years, research focused has been on the development of active and stable catalysts for hydrogen (H2) production by steam methane reforming (SMR). However, there is less attention on the individual and interaction effect of key process parameters that influence the catalytic performance of such catalysts and how to optimize them. The main objective of this study is to investigate the individual and interaction effects of key parameters such as methane partial pressure ( PCH4true) (10‐30 kPa), steam partial pressure ( PH2normalO()gtrue) (10‐30 kPa), and reaction temperature (T) (750‐850°C) on H2 yield and methane (CH4) conversion during SMR using Box‐Behnken experimental design (BBD) and response surface methodology. The H2 production was catalyzed using Ni/LSCF prepared by wet impregnation method. The evaluation of the Ni/LSCF using different instrument techniques revealed that the catalyst exhibited excellent physicochemical properties suitable for SMR. Response surface models showing the individual and interaction effect of each of the parameters on the H2 yield and CH4 conversion were obtained using the set of data obtained from the BBD matrix. The three parameters were found to have significant effects on the H2 yield and CH4 conversion. At the highest desirability of 0.8994, maximum H2 yield and CH4 conversion of 89.77% and 89.01%, respectively, were obtained at optimum conditions of 30 kPa, 28.86 kPa, and 850°C for PCH4, PH2normalO()g, and temperature, respectively. The predicted values of the responses from the response surface models were found to be in good agreement with the experimental values. At optimum conditions, the catalyst was found to be stable up to 390 minutes with time on stream. The characterization of the used catalyst using thermogravimetric analysis, scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, and transmission electron microscopy showed some evidence deposition of a small amount of carbon on the catalyst surface.
