摘　　要：采用一锅法制备ZIF-67包覆Pd粒子的Pd@ZIF-67,以吡啶为碳源,通过高温热解在多孔碳上生长碳纳米管(CNT),制备具有碳纳米管/多孔碳包覆PdCo粒子的PdCo@CNT/C,考察催化剂制备条件及其催化糠醛转移加氢制糠醇性能。结果表明,掺杂Pd组分能提高Co基催化剂糠醛转移加氢活性,并改善糠醇选择性。与单一多孔碳结构的PdCo@/C相比,具有碳纳米管/多孔碳结构的PdCo@CNT/C表现出更高的催化活性。Pd@ZIF-67 with Pd particles coated with ZIF-67 was prepared by one pot method.A carbon nanotube/porous carbon coated-PdCo particles catalyst(PdCo@CNT/C)was prepared by growing carbon nanotube on porous carbon through high-temperature pyrolysis with pyridine as carbon source.The preparation conditions of PdCo@CNT/C and the catalytic transfer hydrogenation of furfural to furfuryl alcohol over PdCo@CNT/C were studied.The results indicated that doping Pd components in Co could enhance the activity of Co based catalyst for furfural transfer hydrogenation and improve the selectivity of furfuryl alcohol.PdCo@CNT/C with carbon nanotube/porous carbon structure exhibited higher catalytic activity for furfural transfer hydrogenation than PdCo@/C with porous carbon structure.
