Nice work!

Your XRD pattern is great. In our case, XRD was nice when the chemical etching condition was 0.5 M (HNO3). https://doi.org/10.1016/j.mssp.2019.104888
This is a great work!

Have you consider doping in order to enhance photoactivity?

We haven't tried doping the ZnO particles, we will take it into consideration for furthers tests, thank you for your comment.

Excellent work!

I have a couple of doubts, the nanosheets are agglomerated when performing the photocatalysis? If so, does this generate any inconvenience in the photocatalytic activity of your catalyst? And my second doubt is if you recover the ZnO after photodegradation?

Regards!

We do not know how agglomerated the nanosheets are during the photocatalytic experiments. There is a possibility that they agglomerate, but we try to make the solutions as homogenous as possible by dispersing the nanosheets with ultrasound. Depending on the level of agglomeration I think that it may lower the photocatalytic activity because less active sites may be exposed when the particles agglomerate.
We have not tried to recover the nanosheets after the tests, but we are planning to do it to evaluate the reutilization of the particles.
