Cycling instability is a persisting problem in heterogeneous catalysis. Here we report an efficient strategy to enhance the recyclability of catalysts by situ entrapment active nanoparticles mesoporous carbon. A hard template method was used fabricate desired catalyst, where Al2O3 employed as and polyphenols were carbon source well stabilizing agent. Based on N2 adsorption/desorption analysis, adopt high surface area feature pores. Additionally, noble metal (Pd) found be entrapped inside matrix with good dispersion. The as-prepared highly various hydrogenations CC containing substrates (quinoline, cinnamaldehyde, etc.) exhibited excellent cycling stability without any significant loss activity for 10 recycles, which superior that commercial Pd/C catalyst.
