Round 1

Reviewer 1 Report

This article discusses on the applicability of materials derived from the conducting polymer, polyaniline (PANI), for the oxygen-to-hydrogen peroxide electro-conversion in an alkaline medium. It is part of a series of other papers published by the authors (references [19, 20]) on the aforementioned subject and complement very well their last results. In general, the paper is very-well written and the results very significant for the area of electrocatalysis, in special for H2O2 synthesis. It is recommended its publication in the present form. 

Author Response

We would like to thank the reviewer for the careful reading of our manuscript and for the valuable comment.

Reviewer 2 Report

The aim of this study was to investigate the potentiality of oxygen-to-hydrogen peroxide electro-conversion at electrocatalysts made of polyaniline modified or not by nickel and cobalt species and having undergone or not a thermal treatment. The selectivity and faradaic efficiency were evaluated by complementary electroanalytical methods of rotating ring-disk electrode and electrolysis combined with spectrophotometry. It was found that the presence of cobalt species inhibits the performance.

 

The paper is interesting, and the obtained results are nicely correlated. However, paper is accepted for publication, after major amendments as addressed below.

 

Major amendments:

 

  1. The authors should correlate the obtained results with previously published spectroscopic results by FTIR and Raman spectroscopy.

Author Response

We would like to thank the reviewer for the careful reading of our manuscript and for the valuable comments. We have revised the manuscript to provide more correlation between the electrocatalytic and physicochemical properties in pages 9 and 10.

Round 2

Reviewer 2 Report

The authors revised the manuscript as per reviewer's comments. The amended manuscript is acceptable for publication.
