Research Progress of Nanoscale Bismuth Oxide

The progress of the synthesis and applications of nanosized bismuth oxides is reviewed in this paper. Synthetic methods including solid-phase synthesis, precipitation process, hydrolysis method, sol-gel, atomizing-combustion technique, microemulsion method are systematically introduced. Potential applications of nanosized bismuth oxide as functional electronic materials, burning rate catalysts, photocatalytic decomposition materials, optical materials, medical composite materials and anti-radiation materials are also introduced.
