One-step synthesis of B-doped mesoporous carbon as supports of Pd nanoparticles for liquid phase catalytic hydrodechlorination

摘要

B-doped ordered mesoporous carbon (BOMC) was used as support to immobilize Pd nanoparticles and exhibited an excellent catalytic performance for the liquid phase catalytic hydrodechlorination of 4-chlorophenol (4-CP) using aqueous formic acid-formate solutions as hydrogen source. BOMC was synthesized via one-step hydrothermal route using boric acid as a boron source and resorcinol/hexamethylenetetramine as a carbon source by a self-assembly process with Pluronic F127 in aqueous solutions. The Pd/BOMC catalyst exhibited an excellent catalytic activity and stability which might be due to the synergetic effects between the stabilized Pd nanoparticles and the mesoporous structure of B-doped supports.
