W10O324− polyanion was well integrated with g-C3N4 photocatalyst.
Graphene modified (C16H33(CH3)3N)4W10O32/g-C3N4 composites were synthesized.
8.0 wt% (C16H33(CH3)3N)4W10O32/g-C3N4/rGO showed excellent photocatalytic activity and reusability toward methyl orange and phenol photodegradation.
A photocatalytic mechanism of the (C16H33(CH3)3N)4W10O32/g-C3N4/rGO was well proposed.
