文摘
- •
A heterojunction structure of hybridized g-C3N4 and a stable iron-based MOF was reported for the first time.
- •
100% of visible light-induced MB degradation was achieved within 120 min.
- •
The synergy index of the lp-2 / visible light / H2O2 system was enhanced by 306%.
- •
Dramatically reduced recombination rate of photo-induced e−-h+ pairs on g-C3N4 and facilitated hydroxyl free radical generation on the lp-2 are verified by the electron spin resonance technique and photoluminescence analysis.
- •
The mechanism of enhanced photo-induced Fenton-like activation of H2O2 was illustrated.
