用XRD、SEM、HRTEM、EDAX、BET吸附等温线、IR和维斯光谱等技术对所合成的纳米多孔二氧化钛负载金进行了表征。通过有机叠氮化合物与多种末端炔在水中的1，3-偶极环加成反应研究了该催化剂在绿色有机合成中的催化效率。反应区域选择性地进行，以良好至优异的产率产生相应的1，4-二取代的-1，2，3-三唑衍生物。
Nanoporous titania-supported gold nanoparprecipitation method, and the synthesized nanoparticles have been characterized by XRD, SEM, HRTEM, EDAX, BET adsorption isotherm, and IR and UV vis spectral techniques. The efficiency of this catalyst toward green organic synthesis has been studied by carrying out the 1,3-dipolar cycloaddition of organic azides with a variety of terminal alkynes in water. The reaction proceeds regioselectively yielding the corresponding 1,4-disubstituted-1,2,3-triazole derivative in good to excellent yield.
