摘要：
Hydrotalcite-supported Pd-Au nanocatalysts were found to be efficient heterogeneous catalysts for Ullmann homocoupling reactions of aryl bromides or chlorides at 25 or 40 degrees C, which could be due to the ensemble effect and increased electron density of Pd sites on Pd-Au nanoparticles, and the assistant role of the hydrotalcite for the reversion of the catalytic active center, Pd(0).
