Highlights
- g-C3N4-mNb2O5 composites were obtained by in situ hydrolysis deposition and solvothermal treatment.
- Under the visible light irradiation, 4% g-C3N4-mNb2O5 exhibited the highest photocatalytic activities to degrade rhodamine B (97.5% degradation within 180 min) and tetracycline hydrochloride (75.7% degradation within 60 min) solution with excellent stability and recyclability.
- The g-C3N4-mNb2O5 composites showed narrower band gap, lower PL intensity and larger surface area than pure mNb2O5 and g-C3N4, leading to a significant enhancement of their photocatalytic activity.
