A high performance Pd/C catalyst (Pd/C-PC) was successfully prepared by simple incipient wetness impregnation followed the process of dry plasma reduction and calcination. Oxygen-containing group surface-fuctionalized activated carbon used to absorb palladium precursor PdCl42−, small sized (1.92 ± 0.75 nm) Pd nanoparticles were formed in Pd/C-PC, which smaller than those low pressure cold (4.0–4.5 nm). The results XRD, XPS, TPR TEM showed that with calcination could completely remove...
With increasing applications of metal-organic frameworks (MOFs) in the field gas separation and catalysis, preparation performance research encapsulating metal nanoparticles (NPs) into MOFs (M@MOF) have attracted extensive attention recently. Herein, an Ru@UiO-66 catalyst is prepared by a one-step method. Ru NPs are encapsulated situ UiO-66 skeleton structure during synthesis framework via solvothermal method, its catalytic activity for CO2 methanation with synergy cold plasma studied. The...
The dye wastewater produced in the printing and dyeing industry causes serious harm to natural environment. TiO2 usually shows photocatalytic degradation of under irradiation ultravilet light rather than visible light. In this work, a large number oxygen vacancies Ti3+ defects were generated on surface nanoparticles via Ar plasma. Compared with pristine nanoparticles, as-obtained plasma-treated (Ar-TiO2) make energy band gap reduce from 3.21 eV 3.17 exhibit enhanced organic dyes. Ar-TiO2...
Effective catalytic removal of 4-nitrophenol (4-NP) in industrial wastewater remains a significant challenge due to the lack highly efficient and stable catalysts. Herein, we demonstrated promising plasma method for facile, ultra-fast low-temperature synthesis graphite oxide (GO)-supported palladium catalyst (Pd/GO-P) rich oxygen-containing groups (OCGs) defects with smaller Pd nanoparticles (NPs) 4-NP reduction. The limited damage OCGs retained more (mainly alkoxy hydroxyl groups) on GO...
A fast, facile and environmentally friendly method for synthesizing supported Pd–Cu alloy nanoparticles with enhanced CO oxidation activity is reported.
As an important type of metal–organic framework (MOF), Zr-MOF shows excellent CO2 adsorption performance. In this work, a was synthesized by solvothermal method and adopted to support Ru through simple incipient-wetness impregnation. Then the Ru/Zr-MOF applied for hydrogenation with assistance dielectric barrier discharge (DBD) plasma. The results showed that methane produced selectively under synergistic effect between plasma catalyst, selectivity yield reached 94.6% 39.1%, respectively....
Non-thermal plasma treatment has great potential to open a fast and green route for controllable synthesis of highly active supported metal catalysts.
Designing electrocatalysts with superior activity and stability to Pt/C for the highly efficient pH-universal electrochemical hydrogen evolution reaction (HER) still remains an urgent challenge. Herein, we report a facile plasma method preparation of defect-rich flexible carbon cloth decorated ultralow-loading (0.1 wt%) PtRu alloyed nanoclusters (PtRu/CC-P) resolve these problems. Remarkably, developed PtRu/CC-P catalyst delivered high mass 3.77 A mg-1 (η = 100 mV), almost 3.6 times higher...
The interactions between plasma and liquids cause complex physical chemical reactions at the gas-liquid contact surface, producing numerous chemically active particles that can rapidly reduce noble metal ions. This study uses atmospheric-pressure surface dielectric barrier discharge (DBD) to treat ethanol aqueous solutions containing precursors, stable gold, platinum, palladium colloids are obtained within a few minutes. To evaluate mechanism of reduction precursors by DBD plasma,...
Surface dielectric barrier discharge (DBD) was used for atmospheric-pressure plasma CVD of TiO2 films from TiCl4 and O2 the first time. Under this experiment, deposition rate estimated at 22 nm min−1 by scanning electron microscope observation as-deposited were amorphous as evidenced Raman analysis. The photocatalytic application in removing HCHO simulated air examined a continuous flow reactor. after calcination 350 or 450 °C notably photocatalytically active complete oxidation formaldehyde...
