文摘

Gadolinium-doped silver orthophosphate spherical nanoparticles were synthesized. By Gd doping in Ag3PO4, its photocatalytic performance was considerably enhanced. RB19 photocatalytic degradation mainly occurred on Gd-doped Ag3PO4 by h+h+and O2−. An empirical kinetic model was developed to predict the first order rate constant. Photocatalytic Degradation byproducts of RB19 on Gd-doped Ag3PO4 were identified.
