The NiCo2O4–ZnO–Co3O4–/N–C micro-cage was successfully synthesized by calcination of the precursor obtained from a hollow ZIF-8/ZIF-67 with nickel nitrate. The preparation process concerning ion exchange and leaching was illustrated by the investigation of the composition and structure of the composites. As a catalyst for the activation of persulfate (PDS) to degrade bisphenol A (BPA), it was discovered that the BPA degradation in the presence of NiCo2O4–Co3O4–ZnO/N–C was more efficient than the solids obtained by ZIF-67 with nickel nitrate, indicated by the sevenfold increase of the apparent reaction rate. The further electrochemical analysis evidenced that the electron transfer was more easily accomplished in the system of BPA–PDS–NiCo2O4–Co3O4–ZnO/N–C. This enhanced activity of NiCo2O4–Co3O4–ZnO/N–C was mainly due to the hollow structure, the synergistic effect of NiCo2O4, as well as the smaller size of the active species, which facilitated the transportation of molecules and ions as well as the activation of PDS.

空心 NiCo2O4–ZnO–Co3O4–/N–C 微笼通过激活过硫酸盐协同降解双酚 A
通过将中空ZIF-8/ZIF-67获得的前驱体与硝酸镍一起煅烧，成功合成了NiCo 2 O 4 –ZnO-Co 3 O 4 –/N-C微笼。通过对复合材料组成和结构的研究，阐述了离子交换和浸出的制备过程。作为活化过硫酸盐（PDS）降解双酚A（BPA）的催化剂，发现NiCo 2 O 4 –Co 3 O 4 –ZnO/N-C存在下BPA的降解效率比通过 ZIF-67 与硝酸镍获得的固体，表观反应速率增加了七倍。进一步的电化学分析表明，BPA-PDS-NiCo 2 O 4 -Co 3 O 4 -ZnO/N-C体系中的电子转移更容易完成。NiCo 2 O 4 –Co 3 O 4 –ZnO/N-C的活性增强主要是由于其中空结构、NiCo 2 O 4的协同效应以及较小尺寸的活性物质，有利于分子和离子的运输以及PDS的激活。
