摘　　要：本文采用马弗炉高温煅烧前驱体三聚氰胺得到石墨氮化碳,然后用一锅法将钯纳米颗粒负载在石墨氮化碳上得到了Pd NPS@g-C_(3)N_(4)。利用透射电子显微镜(TEM)、X射线衍射(XRD)以及X射线电子能谱(XPS)等表征手段对其进行表征。以电催化Pd NPS@g-C_(3)N_(4)纳米颗粒的体系实现对水体中的4-氯苯酚(4-CP)的高效脱氯。通过叔丁醇淬灭实验明确该体系去除4-CP的机理包含直接和间接电子转移两种途径,并通过循环实验证实了该体系去除4-CP拥有良好的稳定性。In this paper,mav furnace was used to obtain graphite carbon nitridet by calcinating melamine.And then loading the Pd nanoparticles on graphite by one-pot carbon nitride yielded Pd NPS@g-C_(3)N_(4).The synthetic materials was characterized by transmission electron microscope(TEM),X-ray diffraction(XRD)and X-ray electron spectroscopy(XPS).The hydrogenation and dehination of 4-CP in water was realized by electrocatalytic Pd NPS@g-C_(3)N_(4) nanoparticles.Through tert-butanol quenching,the mechanism of 4-CP removal in this system included two pathways:direct and indirect electron transfer and confirmed that the removal of 4-CP by this system possessed good stability by circulating experiments.
