Fund Project: This work was supported by the National Natural Science Foundation of China (21507130), the Chongqing Science and Technology Commission (cstc2016jcyjA0070, cstc2014pt-gc20002, cstc2014yykfC20003, cstckjcxljrc13), and the Open Project Program of Chongqing Key Laboratory of Catalysis and Functional Organic Molecules from Chongqing Technology and Business University (1456029).

To investigate how the physicochemical properties and NH₃-selective catalytic reduction (NH₃-SCR) performance of supported ceria-based catalysts are influenced as a function of support type, a series of CeO₂/SiO₂, CeO₂/γ-Al₂O₃, CeO₂/ZrO₂, and CeO₂/TiO₂ catalysts were prepared. The physicochemical properties were probed by means of X-ray diffraction, Raman spectroscopy, Brunauer-Emmett-Teller surface area measurements, X-ray photoelectron spectroscopy, H₂-temperature programmed reduction, and NH₃-temperature programmed desorption. Furthermore, the supported ceria-based catalysts' catalytic performance and H₂O + SO₂ tolerance were evaluated by the NH₃-SCR model reaction. The results indicate that out of the supported ceria-based catalysts studied, the CeO₂/γ-Al₂O₃ catalyst exhibits the highest catalytic activity as a result of having a high relative Ce³⁺/Ce⁴⁺ ratio, optimum reduction behavior, and the largest total acid site concentration. Finally, the CeO₂/γ-Al₂O₃ catalyst also presents excellent H₂O + SO₂ tolerance during the NH₃-SCR process.
