文摘
- •
Synthesize and characteristic of GO–B–TiO2 were investigated in this manuscript.
- •
Degradation of 4-NP in a suspended photo catalytic reactor under visible light irradiation was investigated.
- •
The effect of initial COD concentration, initial pH and catalyst loading on photo catalytic performance was investigated.
- •
The modified TiO2 with graphene oxide and boron (GO–B–TiO2) was a novel photo catalyst and it had a a narrower band gap and subsequently higher photo catalytic activity compared to single modified TiO2 (B–TiO2 and GO–TiO2).
