Deactivation of a Ce/TiO2 Catalyst by SO2 in the Selective Catalytic Reduction of NO by NH3
The effects of SO2 on the selective catalytic reduction of NO by NH3 over a Ce/TiO2 catalyst were studied. Conversion of NO remained above 90% in the presence of 100 ppm SO2 at 350 °C for 48 h.Expand
Heterogeneous oxidation of carbonyl sulfide on atmospheric particles and alumina.
TLDR
Experimental results indicate that surface oxygen containing species on the atmospheric particle sample and the Al2O3 sample might be the key reactant for OCS oxidation. Expand
Selective catalytic reduction of NO by NH3 over a Ce/TiO2 catalyst
Abstract Samples of cerium supported on titania with different Ce loadings have been prepared by an impregnation method and tested for the selective catalytic reduction of NO by NH 3 in the presenceExpand
Mechanism of heterogeneous oxidation of carbonyl sulfide on Al2O3: an in situ diffuse reflectance infrared fourier transform spectroscopy investigation.
TLDR
It is revealed that adsorbed OCS could be catalytically oxidized on the surface of Al(2)O(3) to form gas-phase CO( 2) and surface hydrogen carbonate (HCO(3)(-)) and sulfate (SO(4)(2-)) species at 298 K. Expand
Morphology-dependent bactericidal activities of Ag/CeO2 catalysts against Escherichia coli.
TLDR
Experimental results indicated that Ag/CeO2 induced the production of intracellular ROS and disruption of the cell wall and cell membrane and a possible production mechanism of ROS and bactericidal mechanism of catalytic oxidation were proposed. Expand
Mechanism of heterogeneous reaction of carbonyl sulfide on magnesium oxide.
Heterogeneous reaction of carbonyl sulfide (OCS) on magnesium oxide (MgO) under ambient conditions was investigated by in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS),Expand
Review of Ag/Al2O3-Reductant System in the Selective Catalytic Reduction of NOx
Ag/Al2O3 is a promising catalyst for the selective catalytic reduction (SCR) by hydrocarbons (HC) of NOx in both laboratory and diesel engine bench tests. New developments of the HC-SCR of NOx over aExpand
Uptake and conversion of carbonyl sulfide in a lawn soil
Carbonyl sulfide (COS) exchange fluxes between a lawn soil and the atmosphere as well as influencing factors (temperature and water content of soil) were investigated using a static cuvette. TheExpand
Heterogeneous oxidation of carbonyl sulfide on mineral oxides
Heterogeneous oxidation of carbonyl sulfide (OCS) on mineral oxides including SiO2, Fe2O3, CaO, MgO, ZnO and TiO2, which are the main components of atmospheric particles, were investigated using inExpand
Removal of azo-dye Acid Red B (ARB) by adsorption and catalytic combustion using magnetic CuFe2O4 powder
The effectiveness of magnetic CuFe2O4 powder as adsorbent/catalyst for the removal of azo-dye Acid Red B (ARB) from water by adsorption and subsequent catalytic combustion was studied. MagneticExpand
