“…From Figure b, it can be seen that the peak intensity and area of Ti‐O‐Ti peaks at 2,855 cm −1 and 2,925 cm −1 have different degrees of increasing, and the peak intensity of Al‐O absorption at 459, 728, and 1,633 cm −1 significantly reduces. At the same time, the absorption peaks of O‐H at 540 and 3,450 cm −1 are weakened, indicating that oxides of Ti and Sb replace the original O‐H bonds after impregnation and calcination, and Ti‐Sb dual active catalytic components have been successfully introduced onto the surface of particle electrodes (An et al., ). Also, Ti‐Sb dual active catalytic components also can be detected on the surface of Ti‐Sb/attapulgite ceramsite after electrocatalytic oxidation as shown in Figure c.…”

Ti‐Sb/attapulgite ceramsite particle electrodes were prepared for the efficient degradation of chloramphenicol (CAP) in wastewater. To observe the surface morphology and structural characteristics of the Ti‐Sb/attapulgite ceramsite particle electrodes, Fourier transform infrared spectroscopy, X‐ray fluorescence, scanning electron microscopy, and X‐ray diffraction were used for characterization. Parameters affecting the degradation efficiency and the energy consumption of the Ti‐Sb/attapulgite ceramsite particle electrodes, such as current density, electrode distance, initial pH, conductivity, air flow, and packing ratio, were examined. Results showed that the optimal conditions were 20 mA/cm2 current intensity, 3 cm electrode distance, 5,000 μS/cm conductivity, 2.0 L/min air flow, 50.0% packing ratio, and initial pH 1. The removal efficiency of chloramphenicol was 73.7% under the optimal conditions, and the energy consumption was 191.3 (kW h)/kg CAP. Practitioner points Attapulgite ceramsite with good physical performance was prepared. The removal efficiencies for CAP in water by Ti‐Sb/attapulgite ceramsite particle electrodes were studied. CAP was effectively removed by 3‐D electrode system. CAP removal was significantly influenced by operational parameters. Three‐dimensional electrode system shows good degradation ability.

This present work focused on systematically studying the effect of a porous Ti substrate on the surface structure and electrochemical properties of lead dioxide electrodes prepared by anodic deposition under galvanostatic conditions. Characterization experiments, including scanning electron microscopy (SEM), X-ray diffraction (XRD), linear sweep voltammetry (LSV), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), accelerated life time testing and a degradation experiment of methylene blue trihydrate were performed to determine the effect of different Ti substrates. Compared with the planar Ti substrate, the results showed that the porous Ti substrate decreased the grain size of lead dioxide and formed a compact and fine surface coating. The electrode had smaller crystalline particles and a more compact structure. The porous Ti/SnO 2 -Sb 2 O 3 /PbO 2 electrode had a higher oxygen evolution overpotential, a larger active surface area and higher electrochemical activity. The lifetime of the porous Ti/SnO 2 -Sb 2 O 3 /PbO 2 electrode (214 h) was 3.69 times higher than that of the planar Ti/SnO 2 -Sb 2 O 3 /PbO 2 electrode (58 h). Moreover, the degradation rate constant of methylene blue trihydrate on the porous Ti substrate lead dioxide electrode (0.03868 min À1 ) was 1.52 times than that of the planar Ti substrate lead dioxide electrode (0.02542 min À1 ).

“…[20][21][22][23][24][25][26][27] have been studied. 29 PbO 2 electrodes are cheap materials and facile to fabricate, with good electrochemical stability, high oxygen evolution potential and long service lifetime, [30][31][32][33][34] which make PbO 2 electrodes attract much interest. SnO 2 has the advantage of lower cost than other noble metal oxides and is usually doped with Sb to enhance its electrical conductivity.…”

A novel b-PbO 2 /a-PbO 2 /Sb-SnO 2 /TiO 2 nanotube array electrode was fabricated and investigated for the treatment of Acid Red G (ARG) in aqueous solution. Microwave and electrodeposition methods were employed for the deposition of Sb-SnO 2 and PbO 2 on the TiO 2 nanotube array template, respectively.The structure and surface morphology of the composite electrode were characterized by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM). Electrochemical measurements including cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and accelerated life measurements were employed to investigate the electrochemical activity and stability of the hybrid electrode. The obtained composite electrode had an ordered multilayer structure with the TiO 2 nanotube array serving as a tubal template and the Sb-SnO 2 coating as an interlayer, and exhibited an enhanced electrocatalytic activity, long lifetime (815 h) and high oxygen evolution reaction potential.Acid Red G (ARG) was employed as a model organic pollutant for electrochemical degradation to evaluate the electrocatalytic activity of the composite electrode. Several operation variables, such as initial concentration, current densities, initial pH values, temperature of electrolyte, and chloride ions were investigated to explore the removal efficiency of ARG. It was found that low concentration, high current densities and addition of chloride ions could significantly improve the colour removal efficiency.Nevertheless, variables of pH and temperature had little impact on the colour removal efficiency. These results show that the hybrid electrode may become a promising electrode in treating wastewater.
