| 1 | Single-atom site catalysts for environmental catalysis显示文摘In recent decades,the environmental protection and long-term sustainability have become the focus of attention due to the increasing pollution generated by the intense industrialization.To overcome these issues,environmental catalysis has increasingly been used to solve the negative impact of pollutants emission on the global environment and human health.Supported platinum-metal-group(PGM)materials are commonly utilized as the state-of-the-art catalysts to eliminate gaseous pollutants but large quantities of PGMs are required.By comparison,single-atom site catalysts(SACs)have attracted much attention in catalysis owing to their 100%atom efficiency and unique catalytic performances towards various reactions.Over the past decade,we have witnessed burgeoning interests of SACs in heterogeneous catalysis.However,to the best of our knowledge,the systematic summary and analysis of SACs in catalytic elimination of environmental pollutants has not yet been reported.In this paper,we summarize and discuss the environmental catalysis applications of SACs.Particular focus was paid to automotive and stationary emission control,including model reaction(CO oxidation,NO reduction and hydrocarbon oxidation),overall reaction(three-way catalytic and diesel oxidation reaction),elimination of volatile organic compounds(formaldehyde,benzene,and toluene),and removal/decomposition of other pollutants(Hg0 and SO3).Perspectives related to further challenges,directions and design strategies of single-atom site catalysts in environmental catalysis were also provided. | Ningqiang Zhang Chenliang Ye Han Yan Lingcong Li Hong He Dingsheng Wang Yadong Li | 2020 | Nano Research2020，13，12： | 38 |
| 2 | Use of rare earth elements in single-atom site catalysis:A critical review——Commemorating the 100th anniversary of the birth of Academician Guangxian Xu显示文摘Rare earth metals are strategic resources with potential applications in optics,metallurgy and catalysis.In recent years,single-atom site catalysts(SASCs) have attracted increasing attention owing to their 100%atom efficiency and unique catalytic performances.Over the past decade,rare earth elements,including rare earth metals and their oxides,have shown great potential in SASCs.However,systematic analyses of data are still handful.In this mini-review,the use of rare earth metals and their oxides in SASCs was summarized and the results are discussed.A particular focus was paid to the synthetic strategies,characterization of rare earth-containing SASCs,and applications as catalysis supports,promoters and active sites.Current issues faced by rare-earth metals and their oxides in SASCs,as well as future prospects were also provided. | Ningqiang Zhang Han Yan Lingcong Li Rui Wu Liyun Song Guizhen Zhang Wenjun Liang Hong He | 2021 | Journal of Rare Earths2021，39，3： | 4 |

| 4 | Oxidation of Dibenzothiophene in Model Diesel Using Hydroperoxide Generated via In-Situ Reaction of Octane with Oxygen显示文摘The potential of carrying out oxidative desulfurization(ODS) using oxygen as an oxidant was explored in this work. n-Octane firstly reacted with oxygen to produce hydroperoxides in-situ, which were then used as oxidants to oxidize the dibenzothiophene(DBT) in the absence of catalysts. The hydroperoxides generated in-situ were effective in oxidizing DBT to its corresponding dibenzothiophene sulfone(DBTO_2) which was characterized by FT-IR and ~1H-NMR. The removal rate of DBT could reached 98.4% under conditions covering a temperaure of 140℃, a rection duration of 4 h, and an oxygen partial pressure of 0.4 MPa. The influences of different hydrocarbon components in diesel on DBT removal were investigated. The results showed that cyclohexane and n-dodecane had no effect on the removal of DBT, but xylene had a slight negative effect on DBT removal. A possible oxidation mechanism was proposed and the concentration of hydroperoxides in both O_2-oxidized octane and model diesel were detected. | Guo Erliang Li Jianxin Huang Xiaoqiao Duan Yongshen Zhang Lingcong Yan Lijun Lu Shuxiang | 2018 | China Petroleum Processing & Petrochemical Technology2018，20，1： | 1 |
| 5 | In-situ DRIFT assessment on strengthening effect of cerium over FeO_(x)/TiO_(2)catalyst for selective catalytic reduction of NO_(x) with NH_(3)显示文摘Fe-based catalysts have a great potential to be used for selective catalytic reduction(SCR)of NO_(x)with NH3 reaction due to their low cost,nontoxicity and excellent catalytic activity.The aim of this paper is to investigate Ce doping effect on activity of NH_(3)-SCR over the FeO_(x)/TiO_(2)catalyst.In-situ diffuse reflectance infrared fourier transform(DRIFT)technology was utilized to verity the adsorbed species on the surface of FeO_(x)/TiO_(2)and FeO_(x)-CeO_(2)/TiO_(2)catalysts.With respect to the obtained results,among the four catalysts studied,the FeO_(x)-CeO_(2)/TiO_(2)with the FeO_(x)/CeO_(2)ratio of 3/8 shows the best NO conversion more than 98%in the temperature range of 230—350℃,The active centers for NH_(3)adsorption and activation are assigned to Lewis acid sites over the FeO_(x)-CeO_(2)/TiO_(2)and monodentate nitrates can act as the key intermediate in the NH3-SCR.Moreover,both of Langmuir-Hinshelwood and Eley-Rideal mechanisms are observed over the FeO_(x)-CeO_(2)/TiO_(2)catalysts in the SCR. | Hossein Chitsazi Ningqiang Zhang Lingcong Li Xiaojun Liu Rui Wu Junda He Liyun Song Hong He | 2021 | Journal of Rare Earths2021，39，5： | 0 |
