Nano-silver has excellent catalytic activity,it can catalyze a lot of chemical reactions. It took PVP as a reducing agent and surface active agent, silver nano particles was prepared by hydrothermal method treating Ag2 O. Nano-silver catalyst was prepared by using the method of absorption column chro-matography. Nano-silver catalyst Ag/Al2 O3 was used in the reduction reaction of Se6+. The results showed that Ag/Al2 O3 has excellent catalytic activity, it can catalyze the reduction reaction of Se6+ to Se and H2 Se.
