Catalytic Conversion of Sugars into Lactic Acid via a RuOx/MoS2 Catalyst
Round 1
Reviewer 1 Report
After reading the manuscript, I regard it a good paper worthy of publication in this journal. In general terms, I have liked the paper and the findings of this manuscript. I only have a couple of remarks to make. Firstly, I think the role played by CaO is sparsely explained for by the authors and this requires clearly an additional explanation. Secondly, some explanation is to be added as well concerning the nature of the products not accounted for by the mass balance. I guess they should be heavier products so some mention is to be given of this fact. Additionally, I will give a piece of advice to the authors and this would be to carry out GC-MS analyses of their products and check the coincidence with HPLC analyses. This is highly recommended since sometimes this chemistry is tough.

Reviewer 2 Report
Novelty of the Work:
A new data about the catalytic conversion of sugars into lactic acid over a 2 RuOx/MoS2 catalyst were obtained.
Significance of the Work:
In this work the RuOx/MoS2 catalysts were synthesized with the assistance of CaO for the one-pot conversion of glucose to lactic acid. The present work is anticipated to provide valuable insights into the design of multifunctional catalysts for biomass upgrading
Introduction –The authors have to do more relevant discussion about the different type of catalysts used to convert glucose to LA.
Results: The authors should give a more detailed discussion about the mechanism of catalysis RuOx/MoS2 catalysts.
Conclusions - The authors should give an outlook on future research work.

Reviewer 3 Report
Reviewer report:
Manuscript ID: catalysts-2255275
The manuscript is about Catalytic Conversion of Sugars into Lactic Acid over a RuOx/MoS2 Catalyst. The manuscript contain a lot of data and can be published in Catalysts after a major revision.
i) The reaction is performed at 120 deg C. I suggest the authors to remove “mild reaction” condition throughout the manuscript.
ii) Remove the line: the present work anticipated to provide………………….from the abstract. It can be placed in the conclusion.
iii) Abstract should contain summary of the important results based on the obtained data.
iv) Numerically, compare the productivity of Ru based system with fermentation.
v) What is the approximate cost of RuOx/MoS2 Catalyst? Please mention it either in the experimental or in the results and discussion section.
vi) The authors are adding NaOH and CaO to the reaction system for glucose conversion. How much cost does it adding to the product lactic acid?
vii) The focus of the paper is developing a catalytic system. The introduction should focus only on the catalysts. The importance of lactic acid is well known
