摘要

Pure CeO2 catalysts were prepared from different cerium precursors and their activities for selective catalytic reduction of NO with NH3 were investigated in the presence of O-2. The results showed that the catalysts prepared from cerium nitrate have better selective catalytic reduction performance and SO2 resistance. As can be seen from the BET, XRD, TPR, TPD and XPS results, the good performance of the catalysts prepared from cerium nitrate should be resulted from large surface area, good redox ability, high NH3 adsorption capacity and enrichment of Ce3+ on the surface accompanied by an increase of active oxygen content.

Facile control of surface properties in CeO2-promoted Mn/TiO2 catalyst for low-temperature selective catalytic reduction of NO by NH3

Min-Jae Kim, Jae-Rang Youn, Seung-Jae Lee, In-Soo Ryu, Sung Chan Nam, Soon Kwan Jeong, Sang Goo Jeon

Summary: In this study, the surface properties and performance of CeO2-promoted Mn/TiO2 catalysts in the low-temperature selective catalytic reduction (SCR) of NO by NH3 were investigated by changing the impregnation sequence of Mn and Ce. The results showed that the co-impregnated catalyst had higher NO conversion and improved metal dispersion, providing more adsorption sites. Additionally, the acidity of the catalyst could be controlled by changing the synthesis method.

Catalytic performance and mechanistic evaluation of sulfated CeO2 cubes for selective catalytic reduction of NOx with ammonia

Renyi Xie, Lei Ma, Kai Sun, Gang Zhou, Zan Qu, Naiqiang Yan

Summary: Sulfated CeO2 cubes exhibited improved catalytic performance in NH3-SCR due to the increased Bronsted acid sites created by surface sulfates, which facilitated ammonia adsorption and activation. The presence of sulfates on CeO2 cubes did not significantly alter the crystal structures, and gaseous phase NO was identified as the rate-determining step in the SCR reaction over sulfated CeO2 cubes.

Design and identify the confinement effect of active site position on catalytic performance for selective catalytic reduction of NO with NH3 at low temperature

Xiaosheng Huang, Fang Dong, Guodong Zhang, Zhicheng Tang

Summary: In this work, two types of confined catalysts, Pore-CeW/OMT and FW-CeW/OMT, were successfully designed for NH3-SCR process. The results showed that the FW-CeW/OMT structure could effectively prevent the migration and aggregation of dispersed nanoparticles. The citric acid pretreatment significantly enhanced the catalyst's surface acidity and catalytic activity. The framework confined FW-CeW/OMT exhibited a wide operating temperature window, good thermal stability, and strong sulfur resistance in NH3-SCR process.

Interfacial effects promote the catalytic performance of CuCoO2-CeO2 metal oxides for the selective reduction of NO by CO

Yajun He, Jun Liu, Guojie Zhang, Ying Wang, Yuqiong Zhao, Guoqiang Li, Yongfa Zhang, Dengke Lv

Summary: The establishment of strongly coupled heterojunction interfaces between composite metal oxide interfaces is crucial for enhancing the activity of CO-SCR catalysts. A CuCoO2 modified CeO2 catalyst (H-CuCo-CeO2) was synthesized and showed excellent low-temperature activity, achieving 100% NO conversion at 175 degrees C, and excellent resistance to H2O and SO2. Through various tests, the influence of the heterojunction interfaces on the reaction performance was investigated, and it was found that the modification of the CuCoO2 structure promoted the migration of Cun+ species, increased surface active sites, and caused the formation of oxygen vacancies.

Influence of Y Doping on Catalytic Activity of CeO2, MnOx, and CeMnOx Catalysts for Selective Catalytic Reduction of NO by NH3

Eleonora La Greca, Tamara S. Kharlamova, Maria V. Grabchenko, Valery A. Svetlichnyi, Giuseppe Pantaleo, Luca Consentino, Olga A. Stonkus, Olga V. Vodyankina, Leonarda Francesca Liotta

Summary: Novel yttrium-doped CeO2, MnOx, and CeMnOx composites are investigated as catalysts for low-temperature NH3-SCR. The study found that undoped CeMnOx mixed oxide exhibits significantly higher deNO(x) performance compared with undoped and Y-doped MnOx and CeO2 catalysts. The presence of yttrium in CeMnOx lowers the catalyst activity by promoting the competitive NH3-SCO reaction and reducing the amount of NH3 available for NO reduction. The study also analyzed the physical-chemical properties of the prepared catalysts using various techniques.
