Round 1

Reviewer 1 Report

In this article authors Monika Radlik et al reported their work on Pd/Pt bi-metallic catalysts synthesized by impregnation in different series of precursors. The synergetic effect of their bi-metallic catalyst study is very interesting and could be useful. The paper itself is not hard to follow and the methods/results part is well presented. I think the paper is acceptable to publish in its current form. 

Author Response

Reviewer 1 had no specific comments. The manuscript was checked and corrected by a native speaker.

Reviewer 2 Report

In this manuscript authors have synthesized and studied bimetallic Pd-Pt catalysts. In my opinion the concept is not so noble so they could have tested their catalyst for some other chemical reactions too. The language of the manuscript can be improved. Some of the sentences are too long. Conclusion part needs improvement.

Author Response

The revised version was prepared with the help of a native speaker. The section "Conclusions" was extended to cover more experimental findings.

Round 2

Reviewer 3 Report

Thanks the authors for the revised manuscript, the detailed rebuttal letter and the new information added, particularly Table 2SM (comparison of catalytic activity and performance). They have taken into account the remarks and comments and submit a well balanced and improved article that can be accepted with few minor additions if possible:

  • Missing data: could the authors add a sentence explaining why it was not useful to prepare and evaluate samples Pd20Pt80(acac) and Pd20Pt80(Cl), following the reply letter.

  • Same remark for: "Figure 3: the x range between 10 and 30 ° 2 theta is missing." Explain why.

  • Fig. 4 SM: add card numbers in caption.

Author Response

Thanks for the remarks. Our action:

1) Our remark about the 'Missing' catalyst composition (Pd20Pt80) is now at the end of subsection 3.1. (Methods, Catalyst preparation).

2) The remark about showing only the xrd range 30-90 deg. is in caption to figure 3 (main text).

3) Numbers of PDF cards are now in caption to figure  4SM.

 

Thanks again, the authors
