Catalytic combustion technology is one of the effective methods to remove VOCs such as toluene from industrial emissions. The decomposition an aromatic ring via catalyst oxygen vacancies usually rate-determining step oxidation into CO2. Series CeO2 probe models were synthesized with different ratios surface-to-bulk vacancies. Besides devotion surface vacancies, a part bulk promotes redox property in catalytic combustion: tend adsorb and activate gaseous O2 form adsorbed species, whereas...
Catalytic combustion is an advanced technology to eliminate industrial volatile organic compounds such as toluene. In order replace the expensive noble metal catalysts and avoid aggregation phenomenon occurring in traditional heterogeneous interfaces, designing homogeneous interfaces can become emerging methodology enhance catalytic performance of oxide catalysts. A mesocrystalline CeO2 catalyst with abundant Ce-Ce synthesized via a self-flaming method which exhibits boosted for toluene...
Catalytic combustion is an efficient method to eliminate CO and volatile organic compound (VOC) pollutants. CuMn2O4 spinel a high-performance non-noble metal oxide catalyst for catalytic has the potential replace noble catalysts. In order further improve activity of spinel, we propose simple low-cost approach introduce numerous oxygen vacancies simultaneously in situ on surface VOCs. Alkali treatment was used generate (VO), copper (VCu), novel active sites (VO combines with Mn2O3 at...
Metal oxide catalysts like CeO2 exhibit promising prospects to replace the currently used noble metal in catalytic oxidation of volatile organic compounds (VOCs). Although oxygen vacancy is regarded as an active site these novel VOC elimination (e.g., toluene), its actual function and activity remain unclear due limitation following dynamic evolution during reactions. Meanwhile, because involves generation–consumption cycle reactive species rather than being constant, this barrier causes a...
Copper-loaded ceria (Cu/CeO2) catalysts have become promising for the catalytic oxidation of industrial CO emissions. Since their superior redox property mainly arises from synergistic effect between Cu and CeO2 support, dispersion state species may dominate performance Cu/CeO2 catalysts: extremely high or low dispersity is disadvantageous performance. The nanoparticle usually present few contact sites, while single-atom tend to be passivated due relatively single valence state. To achieve a...
Catalytic combustion is a promising technology for removing unburnt CH4 from natural gas vehicle exhaust under lean-burn conditions. Supported Pd catalysts are widely applied and studied use in oxidation at <500–550 °C, with their activities significantly affected by the interactions between support, depending on dispersion, valence state, properties of support. However, whether metal–support favorable catalytic unclear. We therefore used YMn2O5 as catalytically active support to prepare...
In this study, aerodynamic characteristics of a NACA0012 airfoil section whose part the skin upper surface was constructed polydimethylsiloxane membrane (PDMS) were experimentally studied in wind tunnel at Reynolds number (based on chord length) . The aim concept is to take advantage passive vibration an elastic air enhance mixing, which energizes flow near blade surface. As result, separation blades can be delayed or even suppressed, widening usable range angles attack for general-purpose...
