Abstract The present work investigates the kinetics of catalytic ammonia synthesis in a N 2 /H mixture activated by nanosecond pulsed discharge plasma experimentally and numerically. X-ray diffraction, high-resolution transmission electron microscopy x-ray photoelectron spectroscopy are combined to characterize morphology surface electronic properties catalyst. Special attention is placed on role excited species promoting formation important intermediates plasma-enhanced chemistry. A...
Plasma-based dry reforming of methane (DRM) into high-value-added oxygenates is an appealing approach to enable otherwise thermodynamically unfavorable chemical reactions at ambient pressure and near room temperature. However, it suffers from coke deposition due the deep decomposition CH4. In this work, we assess DRM performance upon O2 addition, as well varying temperature, CO2/CH4 ratio, discharge power, gas residence time, for optimizing oxygenate production. By adding O2, main products...
Ammonia is gaining increasing attention as a green alternative fuel for achieving large-scale carbon emission reduction. Despite its potential technical prospects, the harsh ignition conditions and slow flame propagation speed of ammonia pose significant challenges to application in engines. Non-equilibrium plasma has been identified promising method, but current research on plasma-enhanced combustion limited primarily focuses characteristics revealed by kinetic models. In this study,...
Abstract The kinetic effects of non-equilibrium excitation by direct electron impact on low-temperature oxidation CH 4 were investigated experiment and simulation. We focused the vibrational-electronic-chemistry coupling methane oxygen molecules under conditions immediate reduced electric field strengths 30–100 Td in an RF dielectric barrier discharge. A detailed plasma chemistry mechanism governing processes He/CH /O 2 combustible mixture was proposed studied including a set reactions,...
Abstract Ion chemistry with temperature evolution in weakly ionized plasma is important plasma-assisted combustion and catalysis, fuel reforming, material synthesis due to its contribution generation state transition. In this study, the kinetic roles of ionic reactions nanosecond discharge (NSD) temperature-dependent decomposition oxidation methane are investigated by integrated studies experimental measurements mathematical simulations. A detailed mechanism governing processes a He/CH 4 /O...
High quality CZTS nanocrystals were facilely synthesized. The uniqueness is the use of KTB as sulfur activating agent and stabilizer.
PAN hollow fiber functional membrane with heavy metal ion adsorption capacity was prepared via layer-by-layer method using diazo-resin (DR). Ethylenediaminetetraacetic acid (EDTA) and graphene oxide (GO) chelating function were used as modifier. Modification effect studied by Fourier Transform Infrared Spectrometer (FTIR), contact angle test, scanning electron microscopy (SEM) the copper measurement. The result showed that EDTA GO successfully grafted on surface of modified hydrophilicity...
