چکیده

The immobilization of homogeneous catalysts on various support materials is of great interest in catalyst science1-3. However, immobilization of homogeneous catalysts usually decreases the catalytic activity or selectivity2-4, This could be solved using nanoparticles as catalyst supports. Nanoparticulate supports can serve as an intermediate between homogeneous and heterogeneous catalysis4,5. However, nanoparticles are difficult to separate by filtration techniques. One of the most promising MPs supports for the development of high-performance catalyst supports is Boehmite nanoparticles4, The notable advantages of boehmite MPs are simple synthesis, readily available, low cost, high surface area, low toxicity and high stability properties5.Therefore, we have prepared a novel nanoscale catalyst system composed of nanosized Cu catalysts immobilized on Boehmite nanoparticles. The catalyst is readily prepared from inexpensive commercially available starting materials and employed for C-C coupling reactions. Recovery of the catalyst by decantation of the reaction mixture using simple filtration is both convenient and efficient. The ease of recovery, combined with the intrinsic stability of catalyst components, allows the catalyst to be recycled for several times without any discernible loss in activity (Fig. 1).

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
