“…Rhodamine B is a toxic alkaline cationic dye, which was used as a food additive, but has been forbidden due to its high carcinogenic potential (Wu et al, 2018;Lops et al, 2019;Tian et al, 2019;Guo et al, 2020). Furthermore, it can also cause other serious diseases such as visceral disease and red skin staining (Alcocer et al, 2018;Liu et al, 2019;Maria Magdalane et al, 2019). It is very difficult to degrade rhodamine B under natural conditions.…”

No visible light activity is the bottle neck for wide application of TiO 2 , and Boron doping is one of the effective way to broaden the adsorption edge of TiO 2 . In this study, several Boron doped TiO 2 materials were prepared via a facile co-precipitation and calcination process. The B doping amounts were optimized by the degradation of rhodamine B (Rh B) under visible light irradiation, which indicated that when the mass fraction of boron is 6% (denoted as 6B-TiO 2 ), the boron doped TiO 2 materials exhibited the highest activity. In order to investigate the enhanced mechanism, the difference between B-doped TiO 2 and bare TiO 2 including visible light harvesting abilities, separation efficiencies of photo-generated electron-hole pairs, photo-induced electrons generation abilities, photo-induced charges transferring speed were studied and compared in details. h + and · O − 2 were determined to be the two main responsible active species in the photocatalytic oxidation process. Besides the high degradation efficiency, 6B-TiO 2 also exhibited high reusability in the photocatalysis, which could be reused at least 5 cycles with almost no active reduction. The results indicate that 6B-TiO 2 has high photocatalytic degradation ability toward organic dye of rhodamine B under visible light irradiation, which is a highly potential photocatalyst to cope with organic pollution.

“…Electrodes, especially the anode, are the core of the electrochemical system, therefore, numerous studies have been carried out on the various electrode materials [6][7][8]. The most common electrocatalytic anodes include titanium-based electrode (Dimension stable anode (DSA electrode), including PbO 2 [9,10], Sb-SnO 2 [11,12], IrO 2 [13] and (Dimension stable anode (DSA electrode), including PbO2 [9,10], Sb-SnO2 [11,12], IrO2 [13] and RuO2 [14] electrodes), noble metal electrode and graphite electrode (including common graphite electrode and boron doped diamond electrode [15,16]).

A novel electrode consisting of a Ti/PbO2 shell and Fe3O4/Sb–SnO2 particles was developed for electrochemical oxidation treatment of wastewater. Scanning electron microscope (SEM), X-ray diffraction (XRD), the current limiting method, toxicity experiments, and high-performance liquid chromatography were adopted to characterize its morphology, crystal structure, electrochemical properties, the toxicity of the wastewater, and hydroxyl radicals. Acid Red G (ARG), a typical azo dye, was additionally used to test the oxidation ability of the electrode. Results indicated that the 2.5D electrode could significantly improve the mass transfer coefficient and •OH content of the 2D electrode, thereby enhancing the decolorization, degradation, and mineralization effect of ARG, and reducing the toxicity of the wastewater. The experiments revealed that, at higher current density, lower dye concentration and higher temperature, the electrochemical oxidation of ARG favored. Under the condition of 50 mA/cm2, 25 °C, and 100 ppm, the ARG, Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC) removal efficiency reached 100%, 65.89%, and 52.52%, respectively, and the energy consumption and the current efficiency were 1.06 kWh/g COD, 8.29%, and energy consumption for TOC and mineralization current efficiency were 3.81 kWh/g COD, 9.01%. Besides, the Fe3O4/Sb–SnO2 particles after electrolysis for 50 h still had remarkable stability. These results indicated that the ARG solution could be adequately removed on the 2.5D electrode, providing an effective method for wastewater treatment.

“…The material for electrode fabrication plays a major role in determining the efficiency and reactivity of the prepared electrode in an electrochemical reaction. Various electrodes were used in the treatment of synthetic dyes and textile industrial effluents, such as Pt, [14][15][16] boron-doped diamond (BDD), [17][18][19] and dimensionally stable anodes (DSA). [20][21][22] In the current study, metal/graphite composite electrodes were prepared by mixing two different material (metal and graphite) powders with polyvinyl chloride (PVC).…”

In this study, cobalt/graphite-polyvinyl chloride (Co 47.5 /C 47.5 -PVC 5 ) composite electrode was fabricated by mechanical alloying technique. The fabricated electrode and graphite rod were used as anode and cathode, respectively, in the decolourisation of aqueous C. I. Reactive Blue 21 (RB21) and synthetic textile effluent, containing a mixture of azo and anthraquinone dyes. The fabricated electrode showed high efficiency in the decolorisation of aqueous RB21 (99.95%) and synthetic textile effluent. This is further confirmed by the high reduction percentage (>75%) of COD and BOD 5 for both treated samples. The elemental composition study by using FESEM-EDX showed no significant changes in the composition of elements (C, Co and Cl) in the freshly fabricated electrode and after electrolysis of synthetic textile effluent. This showed that the fabricated electrode has a high mechanical strength and strong binding ability between C and Co due to the use of PVC as a binder.
