In this study, ultrathin and easily dispersible gC 3 N 4 nanosheets were obtained by a simple wet ballmilling process. Morphological and structural analysis showed that increasing ballmilling speed resulted in a decrease in both particle size and the number of stacked layers in gC 3 N 4 nanosheets, hence improving their dispersion stability. Thinner nanosheets obtained by ball milling at ...
