“…BDD films are usually fabricated with the chemical vapor deposition (CVD) method, and a substrate is necessary to support the BDD film and improve its stability. [108][109][110] The commonly used substrates include Si, Ta, Ti, Nb, and W, but it is difficult to evaluate the stability of BDD films as a function of substrate type due to the non-uniform preparation parameters among different studies, as well as evident pros and cons of each substrate. 108 Apart from the substrate, another intrinsic property that can heavily influence the electrocatalytic performance of BDD is the sp 3 (diamond)/sp 2 (graphite) carbon ratio.…”

“…It is well known that proper selection of electrode materials is very important for optimizing electrochemical oxidation processes. Numerous types of electrodes including PbO 2 [2][3][4][5], SnO 2 [6,7], IrO 2 [8,9], RuO 2 [10], and boron-doped diamond (BDD) [11] have been investigated. Among these electrodes, SnO 2 and PbO 2 electrodes with low price were believed to achieve good electrocatalytic performance for organic pollutants degradation, based on their high oxygen evolution overpotential.…”

Electrocatalytic oxidation is a promising process for degrading toxic and biorefractory organic pollutants in wastewater treatment. Selection of electrode materials is crucial for electrochemical oxidation process. In this study, Ti/F-PbO 2 and Ti/Sb-SnO 2 electrodes were chosen to compare their electrocatalytic characterization, which were prepared by electrodeposition and thermal decomposition method, respectively. The surface morphology and crystal structure of two electrodes were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The linear polarization curves show that Ti/Sb-SnO 2 electrodes possess higher oxygen evolution overpotential than Ti/F-PbO 2 electrodes. But the stability and corrosion resistance ability of Ti/F-PbO 2 electrode was higher than that of Ti/Sb-SnO 2 electrode. The electrocatalytic activity of Ti/F-PbO 2 and Ti/Sb-SnO 2 electrodes was examined for the electrochemical oxidation of malachite green (MG). The bulk electrolysis shows that the Ti/SbSnO 2 electrodes exhibit the higher electrocatalytic activity for the degradation of MG than Ti/F-PbO 2 electrodes, and the degradation process is good fitting for the pseudo-first order reaction. The higher electrocatalytic activity of Ti/ Sb-SnO 2 electrodes can be attributed to the higher oxygen evolution overpotential.

“…Recently, Ti/SnO 2 anodes were prepared by chemical vapor deposition (CVD) without O 2 as a precursor, avoiding the formation of the TiO 2 passivation layer [44]. These electrodes presented a compact microstructure with high overpotential for oxygen evolution and a superior activity for pollutant oxidation.…”

A Ti/SnO 2 -Sb 2 O 4 electrode was prepared by alternate Sn and Sb electrodepositions using the thermoelectrochemical method. The chemical, electrochemical, and structural characterization of the electrode was performed and it was tested in the anodic oxidation of several pollutants, phenol, ibuprofen, acid orange 7 (AO7), and diclofenac, all in aqueous 0.035 M Na 2 SO 4 solutions at current densities of 10 and 20 mA cm -2 . After the 24 h assay, removal of chemical oxygen demand, total organic carbon (TOC) and absorbance were very high, especially at the higher current density. TOC removals presented the lowest value. However, after 24 h at 20 mA cm -2 , TOC removals were: phenol-94%; ibuprofen-83%; AO7-88%; and diclofenac-73%. Combustion efficiency and instantaneous and mineralization current efficiencies were also determined.
