CrOx Anchored on the Black-TiO2 Surface via Organic Carboxylic Acid Ligand and Its Catalysis in Oxidation of NO
CrO x /black-TiO 2 catalysts were prepared by ligand-assisted (citric acid, oxalic acid and ethylenediaminetetraacetic acid) impregnation method. These catalysts were characterized in detail by means of X-ray diffraction, Raman, BET, X-ray photoelectron spectroscopy, H 2 and O 2 (NO) temperature pro...

/CA (modified by citric acid) revealed excellent catalytic activity and stability for NO oxidation in the temperature range of 200–450 °C. The characterization results exhibited that the interaction existed between CrO
x
and oxygen vacancies resulting in more Cr
6+
. Moreover, the strong interaction between CrO
x
and O–Ti–O was attributed to the modification of carboxylic acid, which increased the content of Cr
3+
and chemical adsorption oxygen. High content of chemical adsorption oxygen promoted the adsorption ability of O
2
, and Cr
6+
enhanced the adsorption capacity of NO. Hence, chemical adsorption oxygen and Cr
6+
synergistically promoted the NO oxidation.
