The as-prepared 3D ternary composite displays superior catalytic performance for the hydrogen evolution reaction (HER), which outperforms most binary or ternary carbon-based composites in the literature. The HER overpotentials are 65 mV and 86 mV when the current densities reach 10 mA cm−2 and 20 mA cm−2, respectively, and the exchange current density reaches 0.503 mA cm−2. Also, it demonstrates good stability reflected from the negligible activity decrease after 1000 consecutive cycles. The excellent electrocatalytic performance of the Co9S8/NSG-UCNT ternary composite is attributed to the co-effect of the abundant HER active sites induced by Co9S8 nanoparticles, structural defects existing in the carbon support caused by N and S co-doping and outstanding conductivity resulting from the 3D structure.23:T457,Ammonia is a promising alternative energy to fossil fuels for reducing CO₂ emissions. Plasma catalysis technology for ammonia production using clean energy is gaining attention. Introducing catalysts to the plasma increases ammonia synthesis rates, but the effect of catalyst particle movement in the plasma region, such as in a fluidized-bed reactor, is less explored. The study investigates plasma catalytic ammonia synthesis using fluidized-bed and fixed-bed dielectric barrier discharge (DBD) reactors with M/Al₂O₃ (M = Co, Ru, Ru-Co) catalysts. Results show the ammonia synthesis rate in the fluidized-bed DBD reactor was significantly higher than in the fixed-bed DBD reactor. This intensified plasma discharge substantially increased ammonia production. The dynamic movement of catalyst particles in the fluidized-bed reactor enhanced the plasma-surface interaction, thereby accelerating the interaction with reactive species and promoting ammonia synthesis. This research provides insights into reactor design and catalyst packing for plasma catalytic ammonia synthesis.24:T412,Plasma catalytic synthesis of ammonia has the advantages of flexible on-off and environmental friendliness, making ammonia a potential vector for renewable energy storage. The synergistic interaction between plasmas and catalyst surfaces remains unclear. In this work, we develop a quantum chemical model based on density functional theory where the plasma environment is simplified. The effect of electric fields and surface electrons on N₂ adsorption and dissociation is studied on the typical catalysts (Ru and Ni) with different surface morphologies. The combined effect of the electric fields and excess electrons will promote the adsorption of N₂ and the weakening of the NN triple bond. It is shown that the electron distribution on the surface is optimized, and the electrostatic interaction between surface atoms and adsorbates is strengthened. The marginal effect has been observed, and the promotion effect on the catalysts with better performance in thermal-catalytic N₂ dissociation is weaker.
