FE-SEM, TEM, and TGA analysis. The results and analysis revealed that bismuth microspheres have better catalytic behavior for the preparation of biphenyl in water as a greenest solvent and for the ring opening of epoxides by nucleophiles including amines, alcohol, and thiol compared to pure Bi(NO3)3. 3H2O under solvent-free condition. Moreover, the novel catalyst could be recovered and reusedat least
硫化
铋的(Bi 2小号3)使用制备升-半胱
氨酸,它作为
硫源和用于形成Bi的定向分子二者2小号3通过溶剂热方法如均相催化剂。通过各种技术,例如XRD,BET,FE-

TEM和TGA分析来检查制备的催化剂。结果和分析表明,与纯Bi(NO 3)3相比,
铋微球对于在
水中以最绿色的溶剂形式制备
联苯以及由胺,醇和
硫醇等亲核试剂环化
环氧化物具有更好的催化性能。3小时2O在无溶剂条件下。此外,该新型催化剂可被回收并重复使用至少四次而不会损失其催化活性。
