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.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
