Enhanced low-temperature NH3-SCR performance of Ce/TiO2 modified by Ho catalyst

Holmium was used as a dopant to boost the low-temperature NH3-selective catalytic reduction (SCR) performance of Ce/TiO2 catalyst. It was ascertained that certain amount of Ho-doping species could exceedingly improve the low-temperature SCR activity under 60 000 h−1 of Ce/TiO2, accompanied with the improvement of tolerance to H2O and SO2 at 200°C. Characterization results manifested that Ho modification could not only result in inhibiting the growth of TiO2 crystals and the enlargement of specific surface area but also lead to the enhanced redox ability and the increased amount of surface-adsorbed substances, all of which could promote the low-temperature NH3-SCR performance of Ce/TiO2.


Recommendation? Accept with minor revision (please list in comments)
Comments to the Author(s) In this study, Ho was used to modify Ce/TiO2 catalyst for NH3-SCR reaction . In my opinion, this manuscript could be accepted for publication after the following revisions: 1. Ho0.35/TiO2 catalyst should be prepared and tested. 2. The XPS spectra of Ho should be given. 3. E-R mechanism should be taken into consideration.

RSC Subject Editor: Comments to the Author: (There are no comments.) ********************************************** Reviewer comments to Author: Reviewer: 1 Comments to the Author(s) In this manuscript, the authors described a study on low-temperature NH3-SCR performance of Ce/TiO2 modified by Ho catalyst. A series of Ce/TiO2 catalysts with different Ho/Ti ratios were examined and compared. The authors designed and performed several experiments such as XRD, H2-TPR, NH3-TPD, DRIFTS analysis etc. to evaluation the effect of Ho on the Ce/TiO2 catalyst. Adequate data and results such as SO2 and H2O tolerance, BET, NH3 adsorption, NO+O2 adsorption have been presented and discussed by the authors subsequently and appropriate conclusion has been drawn. For example, the Ho modified Ce/TiO2 catalyst was able to demonstrate higher intensity of NH3 and NO+O2 adsorption with increasing temperature in the DRIFTS study which well explains the observation that Holmium could effectively improve the low-temperature SCR activity of Ce/TiO2. From this work, the readers would be able to get new insights on the properties of Ho modified Ce/TiO2 catalyst which shows potential applications in various fields. Overall, the manuscript is well presented and meets the requirement as publication on Royal Society Open Science. Therefore, I would recommend this manuscript published after considering the following comments. In the catalytic performance discussion, the authors presented Figure 1a which demonstrated the curve of NO conversion against temperature. Different Ho modified Ce/TiO2 catalysts and the unmodified catalyst were compared here. The authors also indicated that when the Ho/Ti molar ratio rise to 0.45, the NOx conversion over Ce0.35/TiO2 at 150 ℃ was increased from 22 % to 56 %. However, further increasing of Ho/Ti molar ratio to 0.6 made a slight decrease of de-NOx activity in the whole temperature range. Later on, the authors discussed the NO conversion of NO oxidation reaction and presented Figure 7. In Figure 1, the Ho0.45Ce0.35/TiO2 has shown higher NO conversion than Ho0.6Ce0.35/TiO2, however, the result is completely opposite in Figure 7. It is recommended to provide a summary of these observations in the discussion to better serve the readers. Additionally, some figure identification numbers used within the manuscript were not correct. Please verify.
