High-quality boron-doped nanocrystalline diamond (BDND) film was fabricated on mesh titanium substrate using hot filament chemical vapor deposition (HFCVD) system. Raman, X-ray diffraction (XRD), and scanning electron microscopy (SEM) spectroscopy were used to analyze the microstructure of the mesh Ti/BDND electrode. The SEM images show different parts of the mesh electrode surface are fully covered by the diamond film and particle sizes of that are nearly less than 1 μm on average. Additionally, the diamond film of the prepared electrode surface is relatively of high quality and the mesh electrode has a relatively small residual stress from Raman and XRD spectra, respectively. Cyclic voltammograms indicate that the mesh electrode has wide potential window, low background current and stable electrochemical properties in H 2 SO 4 solution, suggesting that the prepared electrode is suitable for the application of wastewater treatment. The COD removal rate of the prepared mesh electrode increases by 10.4% compared with that of the plate electrode, which demonstrates that the ability of the mesh electrode in the wastewater treatment is relatively better.
