在有序介孔 TiO2中原位担载了高分散的 Cu(OH)2,并将其应用于炔烃的氧化偶联(Glaser)多相催化反应,该催化剂表现出很高的催化活性。 Cu(OH)2为催化剂的主要活性组分, TiO2的有序介孔和较大的比表面积有利于 Cu(OH)2的分散以及反应物和产物的扩散,具有重要的应用前景。

Ordered mesoporous titania supported copper hydroxide was used as catalysts in heterogeneous oxi-dative homocoupling of alkynes(Glaser reaction). The results showed high catalytic performance. Highly dis-persed copper hydroxide was regarded as the active site and mesoporous structure of TiO2 benefit the high dis-persion of active sites as well as the diffusion of the reactants and products in the reactions. 1,3-Dyne deriva-tive, the products of Glaser reaction, is an important class of compounds in chemistry and materials science. Thus, Cu(OH) 2 / TiO2 is of great importance in the industrial application.
