“…Meanwhile, the adsorbed RhB molecules are excited to form excited-state RhB* and subsequently injects electrons to the CB of BiOCl (Fig. 8a, step 2) [56,57]. The excited-state electrons transfer to the BiOCl nanosheet surface and react with dissolved oxygen to generate the main active groups of superoxide anion radicals (•O 2 -) ( Fig.…”

A key issue to design highly efficient photoelectrodes for hydrogen production is how to prohibit the rapid carrier recombination. In order to use the visible light and reduce the recombination of electrons and holes, reduced TiO 2-x /BiOCl heterojunctions are successfully synthesized and the photoelectrodes are assembled in this work. The effects of various Bi/Ti molar ratios on the structural, morphological, optical, photoelectrochemical and photocatalytic activities of the resultant samples are investigated systematically. The TiO 2-x nanoparticles contain Ti 3+ , Ti 2+ , and oxygen vacancies (Ov), while the BiOCl nanosheets exposed {001} facet. Ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS) results indicate that the existence of Ti 3+ , Ti 2+ and Ov expand the light-response range. Linear scan voltammetry and electrochemical impedance spectroscopy results indicate that more efficient electron transportation is presented in the heterojunctions with the appropriate Bi/Ti molar ratio. Consequently, the reduced TiO 2-x /BiOCl heterojunction with the most appropriate Bi/Ti molar ratio exhibits a high

“…Because hydroxyl radicals do not produce fluorescence or cannot be detected to have fluorescence, the product of 2‐hydroxy terephthalic acid (HTA) reacted by hydroxyl radicals and terephthalic acid can generate intensified fluorescence and the concentration of hydroxyl free radical is proportional to fluorescence intensity. Therefore, the amount of hydroxyl terephthalic acid can be figured out according to its fluorescence radiation intensity, and the amount of hydroxyl terephthalic acid generated reflects intuitively the relative amount of hydroxyl radicals . In the trapping experiments, the dosage of terephthalic acid was 2 mmol.…”

The sulfide photocatalyst of Zn Fe S was successfully synthesized by a facile microwave-assisted method, and Zn Fe S photocatalysts were characterized using SEM, EDX, XRD and BET. The specific surface area of synthesized Zn Fe S is 78.1 m g , and total pore volume is 0.4 cm g . With bisphenol A (BPA) as a target pollutant, photocatalytic system of UV + Zn Fe S + H O was set up. Some influencing parameters, including H O dosage, initial pH value, initial concentration of BPA and Zn Fe S dosage, were investigated, and the stability of the Zn Fe S was also studied during the photocatalysis. The optimum values of operating parameters were found at an initial pH value of 5.0, a H O dosage of 0.15 mmol L and a Zn Fe S dosage of 0.08 g when the initial concentration of BPA was 10 mg L . Under the optimal conditions, the highest removal rate of BPA achieved 95%. After seven consecutive reaction cycles, the degradation efficiency of BPA could still reach 85% and there was only a little dissolution of Zn and Fe . Compared with the traditional photo-Fenton system, the UV + Zn Fe S + H O system can not only improve the degradation efficiency of BPA, but also reduce the dosage of H O and thus reduce the processing cost.
