摘要：A novel active DSA electrode (ZIF-67 derivative/Ti-x) was formed by coating and calcination strategy using ZIF-67 as a precursor. The structure and composition of the ZIF-67 derivative/Ti-x electrode were characterized by SEM, EDS, XRD, and XPS, and the results showed that the ZIF-67 derivative/Ti-450 electrode prepared by calcination at 450 ℃ had a homogeneous surface metal distribution and a high Co(II) content, a high oxygen vacancy content, and the presence of chemisorbed oxygen. The electrochemical performance was evaluated using LSV, EIS and CV, and it was found that the ZIF-67 derivative/Ti-450 has a high oxygen evolution potential (1.71 V vs SCE) and the smallest charge transfer resistance, Rct = 29.08 Ω; a small Tafel slope (521 mV· dec-1) and a large electrochemically active area (0.062 cm2), which demonstrates its higher intrinsic activity with more catalytically active sites. In general, the synthesized ZIF-67 derivatives/Ti electrodes have good application prospects in the field of degradation of organic pollutants such as p-nitrophenol, which is more difficult to degrade. ? 2023, The Authors.
