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 anchor-ing 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.
