Summary: The current industrial ammonia synthesis heavily relies on the energy-intensive Haber-Bosch process, which leads to significant greenhouse gas emissions. The electrochemical nitrogen reduction reaction (NRR) provides a green and sustainable alternative, but its efficiency has been limited by slow reactivity. Recent advancements in catalyst engineering and electrolyzer development have offered opportunities to improve the performance of the electrochemical NRR. This review focuses on the graphdiyne-based nitrogen reduction electrocatalysts and provides an overview of the electrochemical NRR fundamentals.

Summary: In this study, the properties of ionization waves (IWs) in a multi-pulsed plasma jet were investigated using a two-dimensional computational approach. The IWs were generated by applying three short negative pulses with a repetition frequency of 12.5 MHz. The simulations accounted for both surface charges and space charges accumulated inside and outside the tube. It was found that IWs could emerge from the tube exit at both the rising and falling edges of the pulses, and the remnants of charges played a crucial role in the discharge evolution. The IWs generated by the second pulse significantly increased the plasma plume length, while those generated by the third pulse eventually decayed due to the accumulated charges from previous pulses, which could lead to the extinction of IWs.

Summary: Surface charges exert a significant influence on the evolution of surface dielectric barrier discharge (SDBD). In this study, the impact of residual surface charges on repetitively nanosecond pulsed SDBD in atmospheric air was investigated using a two-dimensional fluid model. It was found that residual surface charges can either enhance or suppress the discharge and energy deposition, depending on their polarity relative to the current high voltage pulse. More residual surface charges are accumulated during the negative pulsed discharge, which has a more pronounced effect on the subsequent positive pulsed discharge.

Summary: A dielectric barrier discharge (DBD) plasma was used to reactivate spent Pd/Al2O3 catalysts, and the gas composition in the plasma process affected the extent of coke elimination and electrochemical performance of the reactivated catalysts. The electrochemical performance was found to improve with the increase of gas flow rate and treatment time for Ar and N2 gases, but decrease for O2 gas. Higher oxidation degrees of Pd reduced the electrochemical performance. This study presents a new strategy for reusing waste catalysts in a simple and environment-friendly manner.

Summary: The Farley-Buneman and Gradient Drift instabilities in a partially ionized dusty electrojet region were investigated using a fluid model. The effects of dissociative electron-ion recombination and dust charge fluctuation on the instabilities were considered. The dispersion relation describing the propagation of electrojet instabilities within the dust ion acoustic range in a magnetized partially ionized dusty plasma was solved numerically and analytically. The results showed that the Gradient Drift instability was unstable at a much longer wavelength compared to the Farley-Buneman instability. The threshold electron drift velocity for Farley-Buneman instability was affected by the charge on dust, with a decrease at lower altitudes and an increase at higher altitudes. Furthermore, the dissociative electron-ion recombination had a stronger damping effect than the dust charge fluctuation on both instabilities.

Summary: A chemical kinetic model was used to investigate the decomposition of tetraethoxysilane (TEOS) in O2/Ar atmospheric pressure dielectric barrier discharge, and the results were compared with gas chromatography and optical emission spectroscopy data. The calculations showed that excited Ar primarily caused carbon-carbon bond cleavage in TEOS in the absence of oxygen. However, in the presence of oxygen, the main decomposition process of TEOS involved the substitution of ethoxy (-OC2H5) by hydroxyl (-OH). The variation of these reactions with oxygen composition could explain the transition of the deposition layer from organic to inorganic. The model and its results provided a theoretical basis for further modeling and regulating the quality of the deposition layer.

Summary: In this study, an environmentally friendly plasma-thermal catalytic process was developed for the sustainable synthesis of ammonia using M/CeO2 and M/MgO catalysts (M = Ru, Fe) in a dielectric barrier discharge (DBD) reactor at atmospheric pressure. The experimental results showed that the support properties played a crucial role in the synergistic effect, with Ru/CeO2 catalyst achieving the highest ammonia synthesis rate of 6.8 mmol g-1 h-1 at 400°C under a N2:H2 ratio of 1:3. The structure-activity relationship of the catalysts was characterized using various techniques, revealing the synergistic effect between plasma and catalyst in increasing the concentration of ammonia.

Summary: This study employed a two-step KI-assisted confined-space chemical vapor deposition method to prepare multilayer WSe2/SnS2 p-n heterojunctions. The optical characterization and electrical tests revealed clear interfaces and vertical heterostructures, as well as good rectification characteristics and high photoresponse. These performances are likely attributed to the ultra-low dark current generated in the depletion region and the high direct tunneling current during illumination.

Summary: Packing heterogeneous catalysts is critical for CO2 conversion into high-value chemicals. In this study, CoO-based catalysts were synthesized, and the treated H-2/Ar-CoO showed four times higher CH3OH selectivity compared to the initial CoO. The plasma treatment significantly increased the oxygen vacancy concentration of H-2/Ar-CoO, leading to accelerated CH3O/OH adsorption and recombination with H/CH3, facilitated by abundant OH/H radicals from H2O.

Summary: In this work, the formation and diffuse discharge of runaway electrons (RAEs) in atmospheric pressure air were investigated using particle-in-cell/Monte Carlo collision simulation, taking into account the field enhancement effect near the cathode surface micro-protrusion. The results showed that the beam amplitude of RAEs is determined by the field enhancement factor and the initial energy of electrons near the micro-protrusion. RAEs precede low energy electrons and guide the discharge propagation by improving pre-ionization, leading to a transition from filamentary discharge mode to diffuse mode and the formation of a wide streamer with a conical shape.

Summary: This study demonstrates the use of plasma hydrogenation technology to efficiently hydrogenate heavy oil model compounds. The results show that hydrogen-rich plasma, compared to methane-rich plasma, has higher density and slower consumption rate of hydrogen radicals, leading to more efficient hydrogenation of aromatic rings. However, an increase in hydrogen radical density may lead to the cleavage of hydrogenated products, undermining the overall effectiveness.
