“…They found that the removal performance of the batch recirculation system can be improved by increasing the flow rate. In our previous study , we have investigated that the electro‐catalytic behavior of a synthesized Bi‐doped TiO 2 catalyst under acidic conditions can be as fast oxidation system for a commonly used methyl blue dye solution. In this study, we would like to illustrate that this electro‐catalytic system is more effective for the degradation of MB/AC binary solution, when comparing with three other more popular advanced oxidation procedures (AOPs): the Fenton system, photo‐Fenton, and TiO 2 ‐photocatalytic systems.…”

A strong hydrogen bond (H‐bond) exists in a binary mixture of dye aqueous solution (e.g. methylene blue, MB) with a ketone (e.g. acetone, AC) contamination. According to the limited literature and our preliminiary results, the MB in an MB/AC binary solution is not degradable (the decolorization percentage is <10%) within 30–40 min of the initiated oxidation process. In this study, we use a Bi‐doped TiO2 electro‐catalytic system, Fenton system, photo‐Fenton, and Bi‐doped or non‐doped TiO2 photocatalytic systems as the oxidation systems for MB/AC binary aqueous solutions. The results show that highly Bi‐doped TiO2 can be used as an effective catalyst in electro‐catalytic systems to realize an H‐bond stabilized dye solution with ketones; the decolorization percentage of electro‐catalytic systems is almost 60% within 30 min, which is better than that of 20% for the Fenton and photo‐Fenton catalytic oxidation systems.

“…The sulfonic group in the S1 molecule renders it thermally stable and highly soluble in water. Afterward, the sulfonic group underwent further desulfonation, resulting in the formation of benzoquinone and phenol that was further oxidized to organic acids and then completely mineralized as many pointed out by literature [30][31][32].…”

Ceria-based composites have been previously developed as functional electrolytes for high performance of solid oxide fuel cells that require high functional electrolyte materials that can provide high ion conductivity for sufficient current output. These composites display hybrid proton and oxygen ion conduction. We developed further composite electrolyte materials containing a catalyst such as rare earth elements; gadolinium (Gd

“…In recent years, considerable studies have focused on the synthesis of Bi 2 O 3 photocatalysts because of strong relationship between morphologies and photocatalytic activities [13][14][15]. Furthermore, some studies have reported that Bi 2 O 3 and its composites also have good electrocatalytic performance [16,17]. However, no reports have been found to use Bi 2 O 3 as catalyst loading on particle electrode for the treatment of wastewater by electrocatalytic performance in 3D system.…”

Bismuth oxide (Bi2O3) and its composites have good electrocatalytic performance. Quartz column is a good kind of catalyst carrier with the characteristics of high mechanical strength and good stability. A novel Bi-modified quartz column particle electrode (BQP) was prepared by the dipping-calcination method. The characterization results revealed that Bi2O3was successfully loaded on quartz column. The optimum preparation condition was calcining at 550°C for 4 h. Electrocatalytic performance was evaluated by the degradation of phenol and the results indicated that the triclinic phase of Bi2O3showed the best electrocatalytic property. Besides, when the dosage concentration of the particle electrode was 125 g/L and the electrolytic voltage was 12 V, the degradation rate of phenol (200 mg/L) reached the highest (94.25%), compared with 70.00% of that in two-dimensional (2D) system. In addition, the removal rate of chemical oxygen demand (COD) was 75.50%, compared with 53.30% of that in 2D system. The reusability and regeneration of BQP were investigated and the results were good. Mechanism of enhanced electrochemical oxidation by BQP was evaluated by the capture of hydroxyl radical.
