Preparation of Ti₄O₇ Reactive Electrochemical Membrane for Electrochemical Oxidation of Coking Wastewater

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The authors presented a study on the preparation of Ti4O7 reactive electrochemical membrane for electrochemical oxidation of coking wastewater

The novelty of the paper is to be clearly stated.

The characterization part is well prepared and well described.

An actual photo of the constructed reactor is to be added.

More details on the experimental measurement techniques and data acquisitions system are to be provided.

The CFD study should be detailed:

-        What is the used software ?

-        What is the numerical method?

-        What is the turbulence model?

-        What is the considered range for Reynold number?

-        The solved governing equations and equations related to the turbulence model are to be presented.

-        The boundary conditions are to be expressed mathematically.

-        A figure presenting the considered geometry with boundary conditions is to be added.

-        A figure presenting the used mesh is to be added.

-        A grid sensitivity test is to be performed.

-        A validation/verification of the numerical model is to be performed.

-        Information about the characteristics of the used computer and computational time are to be provided.

Why is the time limited to 180 min?

The scientific soundness is to be improved by adding physical interpretations.

English level is relatively low and should be improved.

The paper is to be checked for misprints and grammatical mistakes.

Reviewer 3 Report

Comments and Suggestions for Authors

The manuscript reports a Ti4O7 REM microstructure for electrochemical oxidation of coking wastewater. The authors conducted chronoamperometry and computational fluid dynamics simulation to characterize the mass transfer capacity of the material. The manuscript can be published in the "Sustainability" Journal with minor revisions.

The authors should mention the application of rare earth elements in the electrochemical oxidation of coking wastewater in the Introduction section. The following publications present valuable insights on this and can be cited.

https://doi.org/10.1016/j.checat.2022.02.007

https://doi.org/10.1016/j.jre.2021.04.001

The authors should elaborate on the analytical methods used in the experiments so readers can repeat the experiments if needed.
