As a green solvent-free process, ball milling has attracted considerable attention in fabricating nanocomposites. Herein, we synthesized novel Z-scheme heterojunction CeO2/g-C3N4 nanocomposites by simply direct ball milling CeO2 and g-C3N4 at three different mass ratios (3:7, 7:3, and 9:1). In comparison to individual CeO2 and g-C3N4, the ball-milled …
The effects of ball milling time, grinding gap, and grinding passes on structure and properties of CNF were evaluated.
