Ti/SnO2-Sb2Ox-TiO2 Electrodeposited from Methanesulfonate Electrolytes: Preparation, Properties, and Performance

Abstract

In this study, Ti/SnO2-Sb2Ox-TiO2 electrodes were produced using a sol-enhanced electrodeposition technique from methanesulfonate electrolytes. The surface microstructures of Ti/SnO2-Sb2Ox-TiO2 were observed, and their phase constituents were determined. The surface features were analyzed by X-ray photoelectron spectroscopy. Linear sweep voltammetry and degradation tests were also conducted to determine the degradation performance. The results show that the addition of TiO2 sol affects the microstructures of Ti/SnO2-Sb2Ox-TiO2 electrodes, while a uniform coating surface can be obtained at a proper sol concentration in electrolytes. Adding TiO2 sol also causes deep oxidation of Sb and generates more adsorbed oxygen on the electrode surface. The favorable surface features and the well-dispersed TiO2 in the coatings of 10 mL/L TiO2 modified Ti/SnO2-Sb2Ox-TiO2 electrodes award them the best electrocatalytic performance, and their uniform coating surface prolongs the electrode service life.

Effects of Preparation Parameters on the Structural and Morphologic Properties of SnO2-Sb Coatings

“…Figure 4b-d revealed that Sb 3+ and Sb 5+ were present in the SnO 2 -Sb coatings, corresponding to the two oxidation states for Sb that existed in the SnO 2 lattice. Moreover, O lat (i.e., lattice oxygen species) and O ads (hydroxyl oxygen species) are the two oxygen species that were identified, consistent with previous research [31].…”

Review on Structural Adjustment Strategies of Titanium‐Based Metal Oxide Dimensionally Stable Anodes in Electrochemical Advanced Oxidation Technology

“…The removal rate of adsorbable organic iodide reached 80% in the case of Ti/SnO 2 –SbBi, but increased to 82% in the case of Ti/TiO 2 –NT/SnO 2 –SbBi. Zhang et al [ 160 ] also demonstrated that the addition of TiO 2 sol caused the deep oxidation of Sb and produced more adsorbed oxygen on the electrode surface. The good surface characteristics and well‐dispersed TiO 2 in the TiO 2 ‐modified Ti/SnO 2 –Sb 2 O x –TiO 2 electrode coating make it have the best electrocatalytic performance, and its uniform coating surface extends the life of the electrode.…”

Corrosion and Degradation of Materials

“…The global cost of corrosion is estimated to be 3%-5% of the global gross domestic product (GDP), not including individual safety or environmental consequences. To reduce the corrosion cost and to avoid catastrophic corrosion consequences, abundant corrosion studies have been performed and effective corrosion control practices [18][19][20][21][22] have been used to understand the corrosion fundamentals, to inspect the corrosion performance of structural components or materials, to evaluate the safety issues, to analyze and report the corrosion failure, and to develop advanced corrosion control techniques. This benefits the selection and design of the corrosion-resistant materials used in modern society, and their safety assessment.…”
