Ball-milling fabrication of BiAgOS nanoparticles for 808

2021-5-1  BiAgOS NPs were synthesized using the ball milling method. The procedure is described as follows: the obtained Bi 2 O 3-Ag 2 O composite (0.5 g) and Na 2 S (0.97 g) were added to the two spherical tanks. The weight ratio of the ball and mixture was 15:1. Set the ball milled at a speed of 200 rpm for 3 h. BiAgOS NPs were washed by deionized water.
