The effect of oxygen concentration on the catalytic reaction of NOx with soot over BaAl2O4 has been studied by Diffuse Reflectance Fourier Transform Infrared Spectroscopy (DRIFTS). The introduction of O2 into the NO flow can result in a reactant mixture of NO/NO2/O2. Increasing the O2 ...

MnOx catalysts have been proven to have superior activity at low temperatures (LT) for selective catalytic reduction (SCR) of NOx. In this study, spherical mesoporous MnAlx catalysts with different molar ratios were prepared using a simple precipitation method. In addition, their NOx catalytic perfo...
Isoprene (C5H8) globally accounts for half of the non-methane hydrocarbon flux into Earth´s atmosphere. Its degradation is mainly initiated by the gas-phase reaction with OH radicals yielding a complex system of RO2 radicals. Subsequent product format
Among them, Selective catalytic reduction (SCR) of NOx with ammonia is the most widely used method for exhaust gas emission control. The V2O5-WO3/TiO2-based catalysts are one of the most commonly used commercial SCR catalysts, which have an excellent catalytic activity at high temperature around...
The selenocompound 2-phenyl-3-(phenylselanyl)imidazo[1,2-a]pyridine provided protection to human serum albumin (HSA) against HOCl-mediated damage (as assessed by SDS-PAGE) and damage to isolated matrix proteins induced by ONOOH, with a concomitant decrease in the levels of the biomarker 3-...
A thermally stable peroxy acylnitrate was observed to be formed from secondary reactions of pinonaldehyde in the system. This compound has been assigned to 3-acetyl-2,2-dimethylcyclobutane acetylperoxynitrate. Possible implications for the atmospheric NOx chemistry are discussed. From the product ...
A theoretical study of the reaction of β-carotene (BC) with the nitrogen dioxide radical (NO2•) in solution is carried out using the density functional theory (DFT) at the B3LYP/6-31G(d) level, to optimize the molecular geometries, and the polarizable continuum model (PCM), to accoun...
Impact of the new HNO3-forming channel of the HO2 + NO reaction on tropospheric HNO3, NOx, HOx and ozone, Atmos. Chem. Phys., 8, 4061-4068, doi:10.5194/acp-8-4061-2008, 2008. Cariolle, D., Caro, D., Paoli, R., Hauglustaine, D. A., Cue麓 not, B., Cozic, A., and ...
In this study, reaction path analysis and modeling of NOx reduction phenomena by selective catalytic reduction (SCR) with NH3 over a Cu-chabazite catalyst were conducted considering changes in the valence state of Cu sites and local structure due to differences in ligands to the Cu sites. The ...
