Carbon dioxide (CO2) hydrogenation to value-added molecules is an attractive way reduce CO2 emission via upgrading. Herein, non-thermal plasma (NTP) activated over Ru/MgAl layered double hydroxide (LDH) catalysts was performed. The catalysis under the NTP conditions enabled significantly higher conversions (∼85 %) and CH4 yield (∼84 at relatively low temperatures compared with conventional thermally catalysis. Regarding catalyst preparation, it found that reduction temperature can affect...
Nonthermal plasma (NTP)-enabled ammonia synthesis has been recently considered a sustainable technique as compared to the Haber–Bosch (HB) process. Herein, we demonstrated NTP catalytic using mesoporous silica (SBA-15)-supported Ni catalysts under ambient conditions. Specifically, two types of MgO-modified SBA-15 were developed (as catalyst support) by in situ doping and incipient wetness impregnation (IWI) methods, respectively. Experimental results that addition Mg via IWI method favored...
Plasma-assisted catalytic carbon dioxide (CO2) methanation is a promising approach to valorise CO2 under mild conditions, and the system requires rational design regarding both catalysts processes advance it towards practical applications. Herein, bimetallic NiFen/(Mg, Al)Ox were developed for plasma-catalytic methanation, effect of atomic ratio Ni Fe reduction temperature on was investigated systematically. The findings show that higher beneficial formation Ni3Fe alloy abundant surface...
Abstract Structured silicalite‐1 zeolite encapsulated Ni catalyst supported on silicon carbide foam (i.e., Ni@S1‐SiC) was prepared using a new yet simple one‐pot method, showing the significantly improved anti‐sintering and anti‐coking performance in comparison with conventional catalysts Ni/S1, Ni/S1‐SiC, Ni@S1), catalytic dry reforming of methane (DRM).

A NiRu/SiO2 catalyst was prepared by a new method. The presence of polyethylene glycol (PEG) molecules allows their oligomer groups to interact with the metallic ions in liquid, which creates small NiO particles (∼6 nm) that closely contact RuO2 particles, while PEG-free process forms large (∼11 separated on SiO2 after calcination air. formation close contacts between and improves promotional efficiency Ru. Therefore, can be reduced at lower temperature than SiO2, finding contrasts...
Nonthermal plasma (NTP) is a promising alternative to conventional thermal activation for promoting efficient heterogeneous catalysis under ambient conditions. However, full understanding of the hybrid NTP catalyst system challenging due its complexity. Herein, using catalytic CO2 hydrogenation over Ni@SiO2 as model system, we carried out comparative kinetic studies both and conditions assess reaction dynamics kinetics, aimed at interactions between surface. Specifically, performance process...

Abstract Gallium oxide‐based catalysts are promising candidates for CO 2 hydrogenation to methanol, whilst mechanistic understanding of the catalytic systems is not yet fully understood. Here, transient in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) studies over unsupported CuGa and CuGaN (with N doping) were conducted. The findings show that doping could possibly promote formation surface Cu + sites on interface between Ga O 3 , hence increasing selectivity...
