摘要：

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.

Abstract:

Ordered mesoporous titania supported copper hydroxide was used as catalysts in heterogeneous oxidative homocoupling of alkynes(Glaser reaction). The results showed high catalytic performance. Highly dispersed copper hydroxide was regarded as the active site and mesoporous structure of TiO2 benefit the high dispersion of active sites as well as the diffusion of the reactants and products in the reactions. 1,3-Dyne derivative, 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.
