A bismuth-based organic-inorganic hybrid material with layered structure (BiO-BTCIE) was synthesized by taking advantage of an ion exchange reaction. The structure of BiO-BTCIE was examined by XRD, EXAFS, FT-IR, TG/DTA, etc. By replacing the HCOO(-) with BTC anions in the Bi2O2(2+) interlayer, the Bi2O2(2+) layer is distorted as revealed by the EXAFS, which lead to a longer life time of the photogenerated charge carriers and a higher photocatalytic activity of BiO-BTCIE (more than 10 times).
利用离子交换反应合成了一种具有层状结构的铋基有机-无机杂化材料（BiO-BTCIE）。通过XRD、EXAFS、FT-IR、TG/DTA等手段对BiO-BTCIE的结构进行了研究。通过在Bi2O2(2+)层间用BTC阴离子取代HCOO(-)，EXAFS结果表明Bi2O2(2+)层发生了畸变，这导致光生电荷载流子的寿命延长，BiO-BTCIE的光催化活性提高（超过10倍）。
