“…As for the positive charged supported metal ions, the electrons will adsorb on them due to Coulomb attraction, which can prohibit the migration of supported metal ions. This phenomenon was also observed for neutral metal precursor prepared by deposition‐precipitation and co‐precipitation methods . Anyway, as a result of the Coulomb interaction, smaller size of metal NPs are generally obtained by AP cold plasma.…”

“…The enhanced activity was attributed to large amount of surface hydroxyl groups, as well as the abundant low‐coordinated Au species and interface active sites. Di et al prepared Au/TiO 2 catalysts by AP plate‐to‐plate DBD hydrogen cold plasma with a deposition‐precipitation process. The influence of plasma treatment time was investigated, and 4 min reduction prepared Au/TiO 2 catalyst exhibited the highest CO oxidation activity due to the complete reduction of Au ions and less consumption of the oxygen vacancies …”

“…Therefore, deposition‐precipitation method or modified impregnation method are generally adopted to prepare supported gold catalysts to obtain gold NPs with small size and high dispersion. After removing the Cl − ions and drying, Au 2 O 3 was formed, which was further decomposed to generate gold NPs by thermal calcination in air or by AP cold plasma in various atmospheres. As it is a decomposition process, hydrogen‐containing gases are not necessary …”

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.

High performance catalysts for carbon monoxide (CO) oxidation were obtained through thermal activation of a CuBTC (BTC: 1,3,5-benzenetricarboxylic acid) metal-organic framework (MOF) in various atmospheres. X-ray diffraction (XRD), X-ray photonelectron spectroscopy (XPS), N 2 adsorption-desorption measurement, and field emission scanning electron microscopy (FESEM) were adopted to characterize the catalysts. The results show that thermal activation by reductive H 2 may greatly destroy the structure of CuBTC. Inert Ar gas has a weak influence on the structure of CuBTC. Therefore, these two catalysts exhibit low CO oxidation activity. Activating with O 2 is effective for CuBTC catalysts, since active CuO species may be obtained due to the slight collapse of CuBTC structure. The highest activity is obtained when activating with CO reaction gas, since many pores and more effective Cu 2 O is formed during the thermal activation process. These results show that the structure and chemical state of coordinated metallic ions in MOFs are adjustable by controlling the activation conditions. This work provides an effective method for designing and fabricating high performance catalysts for CO oxidation based on MOFs.
