利用原位耦合拉曼显微光谱的腔微电极对氧化铋Bi₂O₃进行电化学研究，能够识别该氧化物在氧化还原过程中的物质转变。研究表明，当施加电势时，电活性物质可能是羟基氧化铋而非Bi₂O₃，而在开路电压下则是Bi₂O₃。（C）2001爱思唯尔科学有限公司。保留所有权利。
An electrochemical study of the bismuth oxide Bi2O3 with a cavity microelectrode coupled in situ to Raman microspectroscopy allowed species transformations during the redox behavior of this oxide to be identified. It was shown that the electroactive species are probably bismuth oxy-hydroxides rather than Bi2O3 when a potential is applied, whereas they are Bi2O3 on open circuit voltage.
