Although you could attempt electrolysis on PET, I don't believe that it would be effective. Hydrolysis is generally used on salts and other compounds that form a lot of ions. When putting less ionic compounds such as H2O through hydrolysis, it's generally necessary to add some salt or acid in order to force more ions to form. Given that PET is even less ionic than water, I doubt that you would have much success trying to electrolyze it.
If your goal is to break down PET, I think it makes more sense to try to break it down using heat instead of electricity. There's an abstract on the results of doing that here:

If your goal is to get rid of plastic waste and save the environment, I would recommend researching better recycling methods for PET.
And if this is for a research project and you're not too set on PET specifically, I would recommend researching ways to manufacture, improve, or reuse bioplastics instead.
Also, to address your last question, PET is made up of covalent bonds.
