Integrating ZnO/Ag2O@g‐C3N4‐Based Nanocomposites Into a Carrageenan Matrix to Efficiently Remove Heavy Metals From Water

Advanced Materials Interfaces, EarlyView.
ABSTRACT This research focused on characterizing graphitic carbon nitride (g‐C3N4) nanocomposites incorporated with ZnO and Ag2O nanoparticles, and carrageenan to remove heavy metals. The ZnO/Ag2O@ g‐C3N4 and ZnO/Ag2O/g‐C3N4@Carr nanocomposites demonstrated thermal stability of 97.40% (108.81°C) and 82.80% (188.99°C) for TGA.
