CO2毒化作用1. As AFC electrodes suffered from CO_2 poisoning, they were believed to be not suitable for transport and research for AFC was almost terminated. 综述了AFC的研究进展,阐述了解决CO2毒化作用的方法,并提出了使用氨作为AFC燃料的发展方向。
We start with a CuO/Al2O3 catalyst and find that while the CO conversion decreases, CO2 accumulates and the average Cu chemical state stays the same. It suggests CO2 self-poisoning, i.e., CO2 desorption is the rate-determining step. Subsequently, experiments are performed to prove this ...

and the final product selectivity, the overall performance of the electrochemical cell is influenced by a series of factors: type of electrolyte and molar concentration [54], pH [55], [56], [57], pressure [58], temperature [59] and eventual poisoning of the catalyst [60], [61], [62]...
Catalysts based on the V2O5/TiO2 and V2O5–WO3/TiO2 systems are being used [324], due to their high activity for NOx removal and low sensitivity to poisoning by sulfur dioxide. However, these catalysts must work at temperatures higher than 350°C, which poses some problems in the process ...
As a result, the Cu4 doped MoS2 could be a candidate for CO oxidation with lower cost and higher activity without poisoning and corrosion problems. With the rapid development of industry, the amount of carbon monoxide (CO) emission, resulted from automobiles, industrial processes and so on, ...
Thus, in comparison with the commer- cial Pt/C catalyst, our Co3O4/RGO composite electrodes are more insensitive to methanol molecules, thus more resistive to poisoning by the possible methanol crossover from the anode of a fuel cell, and are more stable under operating conditions. Discussion...
However, the agglomeration, weaker electrical conductivity, poisoning and fouling toward the chemisorbed intermediates and mechanical instability of metal nanocatalysts significantly impeded the wide spread applications of non-enzymatic glucose sensors, which could be substantially tackled with the composite ...
0.4 V vs. RHE. Comprehensive analysis confirms the emerging space–charge region in the heterostructure interface not only facilitates the targeted adsorption and activation of CO2and N2molecules on the generated local nucleophilic and electrophilic regions, but also effectively suppresses CO poisoning and...
