Near-infrared light-triggered photocatalytic water treatment has attracted significant attention in recent years. In this novel research, rational sonochemical fabrication of Ag2S/g-C3N4 nanocomposites with various compositions Ag2S (0–25) wt% was carried out to eliminate hazardous rhodamine B dye a cationic organic pollutant model. g-C3N4 sheets were synthesized via controlled thermal annealing microcrystalline urea. However, black nanoparticles through precipitation-assisted route. The chemical interactions between and an ultrasonic bath power 300 W. XRD, PL, DRS, SEM, HRTEM, mapping, BET, SAED analysis used estimate the crystalline, optical, nanostructure, textural properties solid specimens. coexistence diffraction peaks implied successful production heterojunctions. band gap energy exceptionally reduced from 2.81 1.5 eV introduction 25 nanoparticles, implying strong absorbability natural solar radiation. PL signal intensity by 40% compared pristine g-C3N4, that enhanced electron–hole transportation separation. rate degradation molecules gradually increased on surface reached maximum for containing Ag2S. radical trapping experiments demonstrated principal importance reactive oxygen species hot holes destroying under charge semiconductors proceeded type I straddling scheme. enriched activity resulted exceptional reduction controlling separation as efficient photothermal photocatalyst. as-synthesized are considered promising photocatalyst types pollutants low-cost sunlight
