“…Interestingly, higher surface ratios or atomic ratios of metal species were obtained by AP cold plasma when using chlorates (such as H 2 PtCl 6 and H 2 PdCl 4 , etc.) as metal precursors . While lower atomic ratios of metal species were observed when using nitrates (e.g., Pd(NO 3 ) 2 ) as metal precursors .…”

“…Di et al prepared various TiO 2 powder supported monometallic photocatalysts (Pt, Ag, Pd) by plate‐to‐plate DBD cold plasma with the assistance of a simple impregnation process using the mixture of Ar and H 2 as working gas. They also prepared carbon and alumina particles supported monometallic (Pd/C, Pd/Al 2 O 3 ) and bimetallic (Pd‐Cu/Al 2 O 3 ) catalysts for carbon monoxide (CO) oxidation using plate‐to‐plate DBD reactor.…”

“…It has been confirmed that the heating of nanoparticles by ions is a critical factor in determining the crystallinity of the nanoparticles . However, the gas temperature of AP cold plasma for synthesizing supported metal catalysts is generally kept below 200 °C . By contrast, electron's high mobility may lead to the net negative charge on the catalysts surface.…”

“…AP cold plasma method is also efficient to meet the requirement of atom economy by forming small size and high dispersion of metal NPs, which can enhance the catalysts performance and decrease the cost. Di et al synthesized Pt/TiO 2 ‐P photocatalysts with various Pt contents using plate‐to‐plate DBD cold plasma. The mean particle size of Pt in Pt/TiO 2 ‐C prepared by conventional thermal reduction method was 3.5 nm, while smaller and narrower size distribution of Pt (1.6 nm) was observed for Pt/TiO 2 ‐P.…”

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.

“…To increase the visible light absorption of TiO 2 materials, transition metals were added into TiO 2 to improve its photocatalytic activity by reducing the energy bandgap width or preventing (e´/h*) pair recombination through electron/hole trapping [10][11][12][13][14][15][16][17][18]. However, it was well-known that the transition metals doped TiO 2 suffered from the poor stability for the long-term operation.…”

Using MnSO 4¨H2 O as manganese source and urea as nitrogen source, Mn/N co-doped TiO 2 loaded on wood-based activated carbon fiber (Mn/Ti-N-WACF) was prepared by sol-gel method. Mn/Ti-N-WACF with different Mn doping contents was characterized by scanning electron microscopy, X-ray diffraction (XRD) and X-ray photoelectron spectroscopies (XPS), and ultraviolet-visible spectrophotometer. Results showed that the loading rate of TiO 2 in Mn/Ti-N-WACF was improved by Mn/N co-doping. After calcination at 450˝C, the degree of crystallinity of TiO 2 was reduced due to Mn/N co-doption in the resulting Mn/Ti-N-WACF samples, but the TiO 2 crystal phase was not changed. XPS spectra revealed that some Ti 4+ ions from the TiO 2 lattice of Mn/Ti-N-WACF system were substituted by doped Mn. Moreover, new bonds formed within N-Ti-N and Ti-N-O because of the doped N that substituted some oxygen atoms in the TiO 2 lattice. Notably, the degradation rate of methylene blue for Mn/Ti-N-WACF was improved because of the co-doped Mn/N under visible-light irradiation.

Direct alkyl sp3 C–H activation to form new C–C bonds is one of the major challenges in synthetic chemistry. Herein, for the first time, we represent a new method, using nano Pd/ZnO which plays both as photoredox and transition‐metal catalyst, for C–C bond formations. By using this catalyst, we have accomplished an oxidative coupling reaction between aryl halides and tertiary amines to yield the corresponding naturally occurring alkyl aryl ketones by using visible light irradiation. Furthermore, the carbonylation process was carried out on a 10 gram scale, with visible light and thermal condition, and it was proved to be scalable, efficient, and economical.
