文摘
- •
A novel electrochemically induced UV/H2O2 (E-UV/H2O2) process was developed.
- •
H2O2 is electro-generated from O2 at a carbon-based cathode during E-UV/H2O2 process.
- •
Different O2 sources (pure O2, air, or O2 from anodic oxidation of water) can be used for cathodic H2O2 production.
- •
The in-situ generated H2O2 undergoes UV-induced photolysis to form
OH.- •
The E-UV/H2O2 process greatly improves the kinetics and energy efficiency of pollutant degradation.
