In recent years,AOPs based on the sulfate radical(SO4·-)have gained wide interest in research.Sulfate radicals can be produced by activation of persulfate(PS)or peroxymonosulfate(PMS).
In this work,a novel carbon quantum dots and Ti3+co-modified TiO2-graphene nanocomposite(CQDs-TiO2-x/rGO)was successfully fabricated via a facile,relatively cheap and environmentally friendly process.
Photocatalysis has been regarded as one of the most promising alternative technology for water disinfection as well as H2 evolution,due to its potential of using sunlight as the energy source.
