Boron-doped diamond (BDD) thin film electrodes have great application potential in water treatment. However, the high electrode energy consumption due to resistance directly limits range of existing BDD electrodes. In this paper, BDD/graphene/BDD (DGD) sandwich structure was prepared, which effectively improved conductivity electrode. Meanwhile, can avoid degradation performance caused by large amount non-diamond carbon introduced heavy doping, such as reduction electrochemical window and decrease physical chemical stability. The microstructure composition were characterized scanning electron microscope (SEM), atomic force microscopy (AFM), Raman spectroscopy, transmission (TEM). Then, citric acid (CA), catechol, tetracycline hydrochloride (TCH) DGD systematically studied total organic (TOC) Energy per unit TOC removal (ECTOC). Compared with single electrode, new improves mobility reduces mass transfer 1/3, showing better treatment performance. process dealing Citric acid, step current 1.35 times that utilization ratio 2.4 (ECTOC) lower than BDD, especially Catechol, reduced 66.9% BDD. a material, has good be used for high-efficiency electrocatalytic pollutants.
