TL;DR: In this paper, an ultrasonic-modified MnO(x)/TiO(2) catalyst was prepared and compared with two different kinds of MnO/TiO (2) catalysts in the process of low-temperature selective catalytic reduction of NO with NH(3), and the physicochemical properties of the catalysts were studied by using various characterization techniques, such as Brunauer-Emmett-Teller (BET) surface measurement, X-ray diffraction (XRD), high-resolution transmission electron microscope (HRTEM), and in situ Fou

TL;DR: In situ FTIR study indicated that the addition of Cr can increase significantly the surface acidity, especially, the Lewis acid sites, and promote the formation of the intermediate -NH(3)(+).

TL;DR: Catalytic activities toward the NO(x) reduction reaction with NH(3) were tested and it was found that with the addition of CeO(2), more NO was removed in a wide temperature range of 220-500 °C and the molar ratio of Ce to Ti-Zr increased significantly and NO conversion increased significantly; after that, increasing CeO (2) content, however, decreased NO conversion.

TL;DR: In this paper, a series of WO3-modified MnOx/TiO2 catalysts were prepared by three different impregnation methods and were investigated by specific surface area measurement, X-ray diffraction, laser Raman spectroscopy, H2 temperature-programmed reduction, high-resolution transmission electron microscopy, and in situ Fourier transform infrared spectrography.

TL;DR: In this article, a series of V2O5-xCeO2/TiO2-ZrO2 (TiZr) catalysts with different CeO2 loadings were prepared, and their catalytic performance for the selective catalytic reduction (SCR) of NOx by NH3 was investigated in the presence of SO2 and H2O.
