“…In the DSPFC system, the BiOCl photoanode used the molecular dye as fuel to generate electrons under visible light irradiation. The electron could be spontaneously transferred through an external circuit from photoanode to cathode to generate electricity. , Therefore, the high photoelectric conversion efficiency could be obtained when massive photoelectrons were generated and transferred effectively on the surface of the photoanode. The short-circuit current density ( J sc ), the open-circuit potential ( V oc ), and fill factor (FF) of the cell with different BiOCl photoanodes are displayed in Table .…”

BiOCl with {010} facets could be a promising material for photodegradation and energy conversion devices such as dye self-photosensitization photocatalytic fuel cells (DSPFCs). However, the {010} facets usually diminish rapidly during the growth process as the result of its high surface energies. In this work, we reported a simple and efficient method to prepare BiOCl with tunable exposed {010} facets. It was found that the solvent used in the synthesis process had important roles in the formation of ultrathin construction and the growth of {010} facets by controlling the [H+]. For decreasing the surface energy and promoting the growth of high-active {010} facets, the thickness of BiOCl and the areas of {001} were reduced in its forming process. We had demonstrated that the enhancement of visible light-harvesting and photosensitization activity of BiOCl was primarily attributed to the decrease of thickness and the growth of {010} facets which could provide large surface areas and more active sites for dye absorption and photoelectron transfer. The BiOCl samples with tunable exposed {010} areas were evaluated as photoanode materials in DSPFCs. As expected, owing to its strong dye absorption capability and high transfer efficiency of charge carriers, the DSPFC with optimal performance was obtained by employing RhB as fuel when BiOCl possessed the larger areas of {010} facets and became a thinner nanosheet structure. Also, the J sc and V oc of DSPFC were measured to be 0.0058 mA/cm2 and 0.689 V, respectively. Meanwhile, approximately 67% color removal was achieved on BiOCl{010}-Pt cell by treating 40 mL of 5 mg/L RhB under visible light for 240 min, which was much higher than that of P25-Pt (4%).

“…Based on the location of O 2p orbital, the VB positions of binary metal oxides are more positive than that of oxidation positions, leading to wide energy bandgaps. [70] Strong solar PFC effect could also be obtained by making the photoanode with other visible-light absorption semiconductor materials, such as WO3/W, [71][72][73][74] ZnO/Zn, [75] Nb2O5 [72] and BiOCl. [76] However, the performance of PFC consisting of CdS/WO3 composite electrode exhibits poor stability due to photocorrosion, poor photoexcited charge separation and unfavorable band structure.…”

“…The effects of different electrolytes such as sodium sulphate, magnesium sulphate, and sodium chloride on the power output as well as the removal efficiency were investigated by Lee et al (2016a) and Khalik et al (2016). Although Lee group found sodium sulphate performed the best in electricity generation, indeed, both groups also noticed that sodium chloride was the best among the three electrolytes.…”

The future prospect in wastewater treatment technologies mostly emphasizes processing efficiency and the economic benefits. Undeniably, the use of advanced oxidation processes (AOPs) in physical and chemical treatments has played a vital role in helping the technologies to remove the organic pollutants efficiently and reduce the energy consumption or even harvesting the electrons movements in the oxidation process to produce electrical energy. In the present paper, we reviewed several types of wastewater treatment technologies, namely micro-nanobubbles, hybrid electro-Fenton processes, photocatalytic fuel cells, and microbial fuel cell. The aims are to explore the interaction of hydroxyl radicals with pollutants using these wastewater technologies, including their removal efficiencies, optimal conditions, reactor setup, and energy generation. Despite these technologies recorded high removal efficiency of organic pollutants, the selection of the technologies is dependent on the characteristic of the wastewater and the daily production volume. Hence the review paper also provides comparisons between technologies as the guidance in technology selection.
