Summary: In2S3/BiOI composites synthesized at room temperature significantly enhance the photocatalytic degradation of tetracycline hydrochloride under visible light irradiation. The heterojunctions of the composites enhance the separation ability of photogenerated carriers, with the 7-In2S3/BiOI composite achieving the best performance. The photocatalytic mechanism of In2S3/BiOI composites involving superoxide radicals and holes is proposed based on photo-electrochemical characterization and free radical tests.

Summary: The present work focuses on the hydrothermal synthesis of Bi2S3 and its doped materials for photocatalytic applications. The Ti-doped Bi2S3/1%NiO nanocomposite showed the highest photocatalytic efficiency among the synthesized samples, with an 80% elimination rate of methylene blue (MB) after 500 minutes of visible light illumination. The high photocatalytic activity can be attributed to the high BET surface area and p-n junction formed between Bi2S3 and NiO, as well as the increased band gap and improved transfer rate of photo-induced electrons due to Ti (IV) doping.

Summary: Combining morphology modification with heterojunction is an effective approach to enhance the photocatalytic activity of TiO2-based photocatalysts for wastewater treatment. In this study, a novel flower-like TiO2/Bi2O3 (FTB) photocatalyst was developed by depositing Bi2O3 nanoparticles on the surface of flower-like TiO2 (FT). The successful formation of p-n heterojunction between flower-like TiO2 and Bi2O3 was confirmed, which facilitates efficient charge separation. Due to the narrow bandgap of Bi2O3 and the unique flower-like microstructure, FTB exhibits a photocurrent 1.67 times higher than that of FT, resulting in a higher photo-degradation rate (92.7%) of levofloxacin compared to FT photocatalyst (approximately 80%). Moreover, FTB demonstrates excellent anti-interference capability towards environmental factors and good cyclability. This work provides new insights into the development of TiO2-based photocatalysts with advanced performance for antibiotic removal.

Summary: The BiOI/BiFeWO6 composites with abundant oxygen vacancies were prepared by combining calcination and solvothermal methods for the removal of different pollutants in water. The morphology of BiOI/BiFeWO6 was characterized by SEM and TEM, and the heterojunction and oxygen vacancies were confirmed by XPS, O 1s spectrum and ESR. Compared with neat BiOI and BiFeWO6, the BiOI/BiFeWO6 composite exhibited excellent photocatalytic properties under visible light.

Summary: This study successfully synthesized various types of thiolated-graphene quantum dots (GQDs) and utilized them in a one-droplet microfluidic paper-based analytical device for the simultaneous multi-sensing of heavy metal ions. The GQDs were functionalized and stabilized on the surface of hydrophobic fiber-glass, enabling colorimetric chemosensing of ions including iron, copper, cobalt, mercury, chrome, manganese, and nickel. The results were confirmed using fluorescence spectrometry, and the platform showed potential for facile metal ion detection in human urine models and environmental fluids.

Summary: Laboratory illumination is strong enough to create a photostationary state (PSS) of amphiphilic azo-benzene compounds in water. The [cis]PSS/[trans]PSS ratios were observed to be 0.33-1.2 in D2O and 0.37-3.8 in dimethyl sulfoxide-d6. ortho-Fluoroazobenzene amphiphiles show higher cis-isomer concentration at equilibrium compared to non-fluorinated compounds due to differences in optical absorption profiles. The kinetics of isomerization were measured using UV-Vis spectroscopy and the ratio of trans-to-cis rates does not directly correlate with the observed PSS. The half-life for PSS formation is 40 minutes for fluorinated compounds and 80 minutes for non-fluorinated compounds.

Summary: This study designed an integrated structure of Cu2O@Au/Cu2O heterostructure particles, which achieved significantly enhanced photocatalytic performance by simultaneously considering the integrated structural characteristics and localized surface plasmon resonance (LSPR) effect. Experimental characterization and theoretical simulation confirmed the three-in-one synergy of the integrated heterostructure, including the LSPR effect of Au nanoparticles, the light scattering based on core-shell heterostructure, and the effective charge separation based on inter-embedded heterostructure. The concept of integrated heterostructure cooperated with LSPR effect provides a new strategy for designing future catalysts.

Summary: In this study, the recombination of separated ion-radical states (SIRS) in PAPh films was analyzed, and it was found that the contribution of X-SIRS recombination to total luminescence varies with different environments. It was also shown that the recombination of labile SIRS is independent of the nature of the atmosphere. The study theoretically substantiated that SIRS recombination can occur via the transfer of both positive and negative charges, and the efficiency of thermal activation of recombination processes depends on the ratio of radiant and conductive channels of energy transfer.

Summary: Bifunctional hybrids containing photochromic indolyl(thienyl) diarylethenes and an ionochromic rhodamine moiety connected by a dimethylene spacer were synthesized. These hybrids exhibit absorption at 450-455 nm and fluorescence at 560 nm in toluene. UV light triggers ring-closed non-fluorescent diarylethene formation, which can be reversed under visible light or in the dark. In the presence of H+ cation, a naked eye effect is observed with the opening of the rhodamine-spirolactam ring and a pink-crimson coloration at 561 nm accompanied by intense long-wavelength emission at 586 nm. This process is reversible by exposure to triethylamine, as confirmed by NMR experiments. The light-induced isomerizations and proton-induced transformations were explained using computational methods. Reversible switching of fluorescent properties can be achieved by light irradiation and proton.
