The study confirms that the ball milled h-BN could be used as a holes transfer promoter for ZnO. However, the finial photocatalytic performance of h-BN/ZnO is determined by the superposition of the two effects for a specific degradation process. This is the reason why the enhancement of ball milled h-BN is only effective for cationic dyes.
