Ag nanoparticles doped g-C3N4 to enhance visible light photocatalytic activity.
TEM images confirmed the homogenous and well distribution of Ag nanoparticles.
0.5% Ag/g-C3N4 is the highest photodegradation rate with 2 times higher than g-C3N4.
The dispersity and size of Ag are the key for enhancing photocatalytic activity.
The MB photodegradation efficiency was decreased after being illuminated five times.
