Influences of Synthetic Parameters on Morphology and Growth of High Entropy Oxide Nanotube Arrays
Round 1
Reviewer 1 Report
The manuscript “Critical Effects on Morphology and Growth of High Entropy Oxide Nanotube Arrays“ is well prepared for publishing. There is just one minor unclear point that could be possible clarified before printing:
Do the authors know the specific surface area of your nanotubes? Did they performed nitrogen physisorption to determine S(BET) or pore size distribution or mercury porosimetry to determine pore radiuses? Two maxima, one for the channels in the nanotubes and second for the space between nanotubes, should be observed. Both are important, the reviewer thinks, mainly for the implication in contact catalysis (Catalysts 2022, 12, 1559. https://doi.org/10.3390/catal12121559). So, adding this info may promote scientific impact of the manuscript.
To sum up, the manuscript focuses on topical theme in material science because porous and stable materials are needed. In the reviewer opinion, the manuscript should be published after minor revision.

Comments for the manuscripts entitled “Critical Effects on Morphology and Growth of High EntropyOxide Nanotube Arrays” was utilization of various scientific domains an overview of, the nanotubes consisting of multicomponent mixed metal oxides are developed, which formed on equi-atomic TiZrHfNbTa high-entropy alloy (HEA). Authors have successfully controlled the anodization parameters (applied voltages and time) and bath compositions (fluoride concentration and water content), we reveal how the synthetic parameters influence the tube growth and morphology formed on equi-atomic TiZrHfNbTa HEA. Finally, authors conclude that, gain insight into the growth mechanism and the feasibility to control the morphology of multicomponent oxide nanotubes. The article is found to be successful in presenting the appropriate and well explained on the ongoing research and conclude the work. But I have some suggestion and recommendations to address the following points before acceptance
1) Abstract needs to be reconstruct by putting problem, scope & experimental techniques, content of the manuscript. In the title the term “critical” is not appropriate for explaining the work. I would like to suggest author should revise the title
2) Why author have chosen equi-atomic TiZrHfNbTa high-entropy alloy (HEA), as models for morphology changes.
3) Kindly highlight the importance of TiZrHfNbTa high-entropy alloy (HEA) in coatings. It may also discuss and compare the results in binary & ternary alloys system
4) Author should also provide the elemental analysis for prepared TaNbHfZrTi (HEA) high-entropy alloy by EDX mapping
5) Author should also the disuse the bonding phenomena of prepared TaNbHfZrTi (HEA)
6) Kindly make sure that correct scientific nomenclature is used throughout the manuscript (e. g., units, Latin names for biopolymers).
7) Conclusion section should be more targeted & better understanding and explore the current challenges.
8) In the TEM analysis, is it possible to HR-TEM & SAED patten or images for understanding the d spacing?
9) throughout the manuscript: separate the numbers from the units (i.e.: 5 mg instead of 5mg)
10) Review the symbol of 0C, K, minutes, ml and hour in whole manuscript
The paper should be minor revision and complete characterization and explanation in order before this work can be further considered for publication.
