DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

In view of the stringent global regulation and increasing R&D demands in NOx removal (DeNOx), this thesis focuses on synthesis, characterization, and applications of Fe-based H-ZSM-5 zeolite catalysts for selective catalytic reduction (SCR) of NO by NH3. This thesis mainly consists of five chapters: Chapter 1 provides an overview and the chemistry, strategy, mechanism, and solid acid catalysts involved in a DeNOx process. Chapter 2 contains experimental details, including catalyst preparation methods, characterization techniques, and experimental procedures invoked during this study. Chapter 3 compares the SCR performances of mono- and bi-metallic Fe-based ZSM-5 catalysts prepared by different methods. Chapter 4 describes the syntheses and SCR performances of Lanthanide metal (Ce, Pr, Nd, and Sm)-incorporated Fe-based ZSM-5 catalysts prepared by reflux method. Chapter 5 summarizes the effect of Si/Al ratio of zeolite support on SCR performances of CeFe-ZSM-5 catalysts prepared by impregnation method. The catalysts so prepared were characterized by a variety of analytical and spectroscopic techniques, such as ICP-MS, XRF, XRD, BET, FE-TEM, H2-TPR, XPS, EPR, NH3-TPD, Pyridine-FTIR, and solid-state 27Al and 31P MAS NMR. It is conclusive that bimetallic catalysts (such as CeFe-ZSM-5) normally exhibit higher NH3-SCR activity (> 94%) over the temperature range of 350-500 oCthan mono-metal catalysts (such as Fe-ZSM-5). The superior SCR activity observed for the bimetallic catalysts has been attributed, for the first time, to the synergistic effect of Bronsted acidity originated from the zeolite support and strong Lewis acidity induced by the incorporated metals.
