The performance over a series of iron-cerium-tungsten mixed oxide catalysts were investigated for selective catalytic reduction (SCR) of NOx with NH3. These catalysts were prepared through critic acid sol-gel process assisted by microwave irradiation, which is a sample, time-saving and economic method to obtain magnetic iron-based catalyst compared with the traditional hydrothermal treatment assistant...
A series of magnetic Fe0.85Ce0.10W0.05Oz catalysts were synthesized by three different methods(Co-precipitation(Fe0.85Ce0.10W0.05Oz-CP), Hydrothermal treatment assistant critic acid sol-gel method(Fe0.85Ce0.10W0.05Oz-HT) and Microwave irradiation assistant critic acid sol-gel method(Fe0.85Ce0.10W0.05Oz-MW)), and the catalytic activity was evaluated for selective catalytic reduction of NO with NH3...
The influence of partial substitution of iron oxide by titanium oxide on the catalytic activity of iron–cerium mixed oxide catalyst for the selective catalytic reduction (SCR) of NOx with NH3 has been investigated in this paper. The methods of X-ray diffraction (XRD) spectroscopy, N2 adsorption–desorption, X-ray photoelectron spectroscopy (XPS) and temperature programmed desorption (NH3/NO-TPD) were...
