摘　　要：Electrocatalysis technology can effectively promote the hydrodechlorination of chloramphenicol(CAP)to reduce the bio-toxicity.However,there are still some challenges such as low degradation rate and poor stability.Here,we prepared porous N,O co-doped carbon supported Pd nanoparticles composites(Pd NPs/NO-C)for electrocatalytic degradation of CAP.The doping of N and O not only effectively enhanced the interaction between substrate and CAP,promoting the mass transfer process,but also enhanced the anchoring effect on Pd nanoparticles,avoiding the occurrence of aggregation.The prepared composites achieved removal efficiency of CAP over 99%within 1 h,and the rate constant was as high as 6.72 h^(–1),outperforming previous reported electrocatalysts.Additionally,Pd NPs/NO-C composites showed a wide range of pH tolerance,excellent ion interference resistance and long-term stability.Our work unravels the importance of mass transfer processes in solution to electrocatalytic hydrodechlorination and provides new research ideas for catalysts design.
