Different visible-light-driven nanocomposites were fabricated via combination of g-C3N4 (CN) with SiC and carbon dots (C-Dots) in the current research work. The features of photocatalysts were investigated by various analyses. The photocatalytic abilities were investigated by removal four aquatic pollutants. The outcomes demonstrated that the CN/SiC/C-Dots (0.25 mL) system has excellent photoability in the elimination of MB, fuchsine, RhB, and CR, which was about 26.9, 20.9, 24.4, and 15.2-folds premier than the single CN, respectively. The boosted photodegradation performance was related to the efficient separation of charges and high visible-light absorption, be- cause of coupling CN with SiC and C-Dots. It was confirmed that the h(+) and O-2(-) plays essential roles in pho- tocatalytic abilities. In our belief, this research work represents a novel method for the production of ternary metal-free nanocomposites based on CN, which could efficiently solve environmental crises.
