Preparation of Co-CNK-OH and Its Performance in Fenton-like Photocatalytic Degradation of Tetracycline

Round 1

Reviewer 1 Report

This is an interesting study regarding to the Cobalt carbon nitride catalyst applied on the Fenton process for the antibiotic removal.

 

In terms of characterization is possible to see a wide range of information, but in the text should be more clearer the presence of cobalt effect. Moreover, the authors should explain why the initial BET of gC3N4 is so low, comparing to other studies on literature.

The authors must follow the leaching of Co after usage. An comment should be adress.

The catalyst concentration and hidrogen peroxide used in the experiment should be referred. Is not clear if authors made an optimization of this conditions.

It seems too much refer at the abstract that this technology can threat a pharmaceutical effluent since just evaluate one antibiotic. Moreover, the initial concentration of TC should be referred at the materials and methods section.

Reviewer 2 Report

1. The abstract need to be more thorough and detail, line 3- among them? what is them?

2. Need to check on simple grammatical errors. 

3. P2, what is the result of K 2p XPS Spectra? Would be helpful if provided

4. Mistakes in sequence of subtopics and topics.

5. Advise to separate into different topic of characterization and photocatalytic reaction results. 

6. Can improvised the conclusion by explain and conclude more details.
