They exhibit unique advantages such as high specific surface area, pH stability, anion storage capacity and regeneration ability, which make them effective adsorbents for removing various anionic pollutants. In this study, it was demonstrated for the first time that LDOs converted the organic pollutant 1,3-DCP in wastewater into epichlorohydrin for further utilization. The results indicate that the conversion rate of 1,3-DCP in LDOs suspension is significantly higher than that in alkaline solution with the same pH owing to the pH buffering effect of LDOs. The reaction mechanism was investigated using XRD, SEM, TG, ion chromatography and elemental mapping. It was confirmed that 1,3-DCP was converted into epichlorohydrin in the alkaline environment of the LDOs dispersion, and the LDOs, along with resulting Cl^–, were transformed into Cl^– intercalated LDHs after reaction.

Ag/Bi co-doped TiO₂ composites decorated with biocarbon (denoted as xAg/Bi-TiO₂/BC) are prepared in this study. Experimentally, the 1.0Ag/Bi-TiO₂/BC photocatalyst shows a superior efficiency toward 90 % removal rate of HCHO (<em>k</em> = 0.0167 min⁻¹) under visible-light irradiation. Further tests are conducted under diverse conditions, including variations in dosage, humidity, and temperature, along with cyclic runs. We observe that the doping sites of Bi and Ag play an important role in the photodecomposition of HCHO. Substitutional doping of Bi can enhance the photocatalytic activity under visible light due to the alleviation of electron-hole recombination and improved light absorption in the visible spectrum. The density functional theory (DFT) shows that Ag in the interstitial site exhibits stronger Ag-Bi interaction than that in the substitution site, resulting in the higher adsorption energy of HCHO and boosting the photocatalytic reaction. Similarly, interstitial doping of Ag causes a red shift in the optical absorption edge, which not only enhances visible light absorption but also serves as an efficient electron transfer mediator. Moreover, possible photodegradation mechanisms and intermediate species are investigated by DFT and in-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS).
