In order to reduce the NOx emission in cement kilns, nickel slag was used to prepare the non-ammonia denitrification material, and a denitrification mechanism was proposed in this study. The results showed that the denitrification material prepared at pH 7 exhibited the best denitrification performance. At low temperature, the highest denitrification performance was achieved between 200 and 300 \u00b0C with a NO decomposition rate of approximately 40%. Then, the NO decomposition rate increased as the temperature increased, reaching over 95% above 700 \u00b0C. The physicochemical characteristics showed that the material had the highest specific surface area and the highest relative Fe content, which benefited the denitrification performance. The divalent iron of the denitrification material was considered the active site for the reaction, and trivalent iron was not conducive to denitrification performance at a low temperature range. After the denitrification reaction, the Fe3+\/Fe2+ increased from 0.89 to 1.31. The proposed denitrification mechanism was the redox process between divalent iron and trivalent iron. This study not only recycles industrial waste to reduce solid waste pollution but also efficiently removes nitrogen oxides from cement kilns without ammonia.<\/jats:p>","DOI":"10.3390\/ma16175859","type":"journal-article","created":{"date-parts":[[2023,8,28]],"date-time":"2023-08-28T06:10:22Z","timestamp":1693203022000},"page":"5859","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Preparation of Denitrification Materials with Nickel Slag for Nitric Oxide Decomposition in Cement Kilns"],"prefix":"10.3390","volume":"16","author":[{"given":"Yanling","family":"Gan","sequence":"first","affiliation":[{"name":"School of Environmental Science and Engineering, Sun Yat-sen University, No. 135, Xingang Xi Road, Guangzhou 510275, China"},{"name":"Guangdong-Hongkong-Macau Joint Laboratory of Collaborative Innovation for Environmental Quality, No. 855 Xingye Avenue East, Guangzhou 511443, China"},{"name":"College of Materials Science and Engineering, Beijing University of Technology, 100 Pingleyuan, Chaoyang District, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenjing","family":"Dai","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Sun Yat-sen University, No. 135, Xingang Xi Road, Guangzhou 510275, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pingli","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Sun Yat-sen University, No. 135, Xingang Xi Road, Guangzhou 510275, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boge","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Sun Yat-sen University, No. 135, Xingang Xi Road, Guangzhou 510275, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suping","family":"Cui","sequence":"additional","affiliation":[{"name":"College of Materials Science and Engineering, Beijing University of Technology, 100 Pingleyuan, Chaoyang District, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"107183","DOI":"10.1016\/j.fuproc.2022.107183","article-title":"Experimental study and CFD modeling of NOx reduction and reductive gas formation in deep reburning of cement precalciner","volume":"229","author":"Li","year":"2022","journal-title":"Fuel Process.
