“…BiO[ClBrI(CO 3 ) 0.5 ] showed the highest strength, indicating that the fourmembered high-entropy material could effectively promote carrier migration and separation. 34 Figure 3d investigates the transmission resistance of photogenerated carriers using electrochemical impedance spectroscopy (EIS). It could be seen that BiO[ClBrI(CO 3 ) 0.5 ] had the smallest EIS Nyquist plot radius, the best interfacial charge separation efficiency, and showed its ability to accelerate the carrier separation rate.…”

We prepared BiOCl, BiO(ClBr), BiO(ClBrI), and BiO[ClBrI(CO3)0.5] materials using a simple coprecipitation method. It was found that adjusting the number of anions in the anion layer was conducive to adjusting the band structure of BiOX and could effectively promote the migration and separation of photogenerated carriers, thus improving the photocatalytic activity. We first selected methyl orange (MO) as the study pollutant and compared it with BiOCl, BiO(ClBr), and BiO(ClBrI). The first-order kinetic constants of MO degradation by BiO[ClBrI(CO3)0.5] increased by 90.3, 33.9, and 3.1 times, respectively. The photocatalytic degradation rate of methylene blue by BiO[ClBrI(CO3)0.5] was 89.5%, indicating the excellent photocatalytic performance of BiO[ClBrI(CO3)0.5]. The stability of BiO[ClBrI(CO3)0.5] was demonstrated through cyclic experiments and XRD analysis before and after the reaction. The photocatalytic degradation of MO by BiO[ClBrI(CO3)0.5] showed that h+ and 1O2 were the main active oxidizing species and •O2 – was the secondary active substance. Overall, our work provides new ideas for the synthesis and degradation of organic pollutants by using two-dimensional anionic high-entropy materials.

“…Encouragingly, significant efforts have been made from various perspectives to improve the visible light photocatalytic activity of BiOCl nanostructures. A fruitful example is that the modification of plasma noble metal nanoparticles on BiOCl nanostructures surface promotes the utilization in visible light region due to the surface plasmon resonance (SPR) of noble metal nanoparticles [31][32][33]. The introduction of gold nanoparticles (Au NPs) can effectively accelerate the transfer of electrons from Au NPs to BiOCl due to the enhanced absorption of visible light and hot electron injection caused by SPR effect.…”

Surface plasmon resonance‐enhanced photoelectrochemical immunoassay of prostate‐specific antigen based on BiOCl‐Au heterojunction

Taking advantage of the high-efficiency photocurrent response of bismuth oxychloride sensitized with gold nanoparticles (BiOClÀ Au) in combination with the antigen-antibody biological recognition reaction, a convenient photoelectrochemical (PEC) immunoassay (model target: prostate-specific antigen; PSA) has been fabricated. In particular, the enhanced photocurrent response could be attributed to the enhanced optical absorption of visible light from surface plasmon resonance (SPR) effect of gold nanoparticles in the hierarchical structure of BiOCl layered. To realize the biological detection process, an immunoreaction was implemented between target PSA and alkaline phosphatase (ALP)-labeled anti-PSA antibodies. With the formation of ternary sandwich immunocomplex, the carried and loaded ALP catalysed the substrate ascorbic acid 2-phosphate (AAP) to generate ascorbic acid for increasing the photocurrent intensity of BiOClÀ Au/FTO. Under optimum reaction time, the photocurrent peak intensity of BiOClÀ Au/FTO increased with the increasing of target PSA concentration in the range of 0.01 ng/mL to 50 ng/mL with a limit of detection (LOD) down to 2.3 pg/mL. In the photocurrent control experiment, the photocurrent of BiOClÀ Au/FTO was not only higher than that of BiOCl/FTO, but also showed greater changes in photocurrent under the same target PSA concentration. Impressively, the proposed split-type PEC immunoassay was applied to detect PSA concentration in human serum samples, giving acceptable and satisfactory accuracy compared with the gold standard PSA ELISA method.
