Enhanced Visible Light Photocatalytic Activity of N and Ag Doped and Co-Doped TiO2 Synthesized by Using an In-Situ Solvothermal Method for Gas Phase Ammonia Removal
Round 1
Reviewer 1 Report
The authors presented a in depth study of application of doped TiO2 in degradation of MB solution and gaseous NH3. Doped TiO2 has been studied a lot for its application in water pollutant treatment, while the degradation of gaseous pollutants hasn’t been fully explored, so this article can be interesting to researchers in relevant field. The article can be improved in following ways:
1) Page 6 result table, it will be great to include a control experiment of MB degradation using UV illumination without presence of catalyst, this presents some baseline info regarding the actual performance of the catalysts used. Also ideally data (average and standard deviation) from repeated runs and data from degradation tests on reused materials should be presented to better assess the robustness of the catalyst.
2) Page 13 material preparation, author should include heat rate for material synthesis/calcination and the model of the furnace so that others can leverage the learning as much as possible.

Reviewer 2 Report
The author should indicate the meaning of BET and BJTH carefully. Regarding experimental conditions of the solvothermal process and so on, the author should indicate them.
Author Response
Dear Reviewer 2,
Thank you for the comment and the opportunity to revise our paper titled "Enhanced visible light photocatalytic activity of N and Ag doped and co-doped TiO2 synthesized by using an in-situ solvothermal method for gas phase ammonia removal"
In response to your comments on the catalyst preparation by solvothermal method and BET and BJH analysis, we have revised and adjusted every relevant sentence in the sections of 3.2 catalyst preparation and 3.3 characterizations (pages 12-13) carefully to clarify our meaning. All revised sentences are marked in yellow in the revised manuscript.
We hope the revised manuscript will better suit the Journal of Catalysts but are happy to consider further revisions, and we thank you for your continued interest in our research.
Sincerely,
Adilah
