Abstract. hBN/ZnO composite photocatalysts were prepared by ball milling of ZnO with hexagonal BN (hBN). The photocatalytic activity of ZnO for the degradation of cationic dyes could be significantly enhanced by coupling with ball milled hBN and the stability of ZnO benefited from the presence of .
For the unmilled sample, the XRD pattern represents Al, ZnO and CuO phases. By increasing ball milling time, intensity of the peaks of Al, ZnO and CuO decreases while Al 2 O 3 (223) peak appears after 60 h milling. In fact, ball milling up to 60 h causes the formation of insitu Al 2 O 3 particles within the matrix. The ZnO (201) peak and CuO ...
To vary the characteristics of ZnO, to meet the challenges, the microstructure is required to be tuned positively. One of the solutions is the formation of ZnO composites with new and versatile reinforcements. We report upon the synthesis of Nanodiamonds (ND)/ZnO nanocomposites using ball milling technique.
