Preparation of graphitic carbon nitride (g-C3N4)/WO3 composites and enhanced visible-light-driven photodegradation of acetaldehyde gas

- g-C3N4/WO3 composite was prepared by simplifying mechanical mixing method.
- Composite exhibited higher visible light activity than bare g-C3N4 and WO3.
- Probable photocatalytic mechanism under visible light was proposed.
- Composite is effective visible-light-driven photocatalyst decompose or remove VOCs.
