Summary: A new p-n type CBO/CN/RGO ternary heterojunction photocatalyst was successfully prepared by ionic liquid-assisted hydrothermal method, which combined three-dimensional multi-stage rosette CuBi2O4 and two-dimensional g-C3N4 and RGO flakes. The construction of p-n heterojunctions significantly improved the transfer and transport speed of photogenerated carriers. The photocatalytic degradation of MO by CBO/CN/RGO-6% reached 91.83% within 150 min, with degradation kinetics constants higher than single-phase CBO and g-C3N4. The CBO/CN/RGO-6% composites showed good chemical stability and are expected to be a preferred material for environmental wastewater treatment.

Summary: In this study, a novel TiO2@g-C3N4@biochar composite photocatalyst was successfully fabricated and characterized. The composite photocatalyst exhibited high photocatalytic oxidation activity for ciprofloxacin (CIP) under UV-vis and visible light irradiation. The photocatalytic removal performance of CIP was influenced by the initial concentration, catalyst dosage, and pH value, and the composite photocatalyst showed excellent stability and reusability. The proposed mechanism of the CIP photocatalytic oxidation reaction provides an effective strategy for removing antibiotics in wastewater.

Summary: In recent decades, pharmaceuticals have become a new category of environmental pollutants due to their presence in water bodies. Metal-free g-C3N4 (GCN)-based composites have gained significant attention for their ability to degrade pharmaceutical compounds. This study prepared and characterized a GCN/BiOCl composite, which showed excellent stability in degrading levofloxacin (LVX) under solar light irradiation. The composite was also effective in degrading other pharmaceuticals in an aqueous phase. Therefore, this work presents an effective method for the simultaneous degradation of pharmaceutical contaminants in water using the GCN/BiOCl composite.

Summary: The properties and interactions of g-C3N4, Bi3NbO7, and g-C3N4/Bi3NbO7 photocatalysts were revealed through various tests. g-C3N4/Bi3NbO7 has a lower band gap and higher absorption of visible light, as well as higher efficiency in separating photogenerated electron-hole pairs. In the photocatalytic reduction of Cr(VI), g-C3N4/Bi3NbO7 is more effective than pure g-C3N4 and Bi3NbO7.

Summary: Nowadays, the concern over antibiotic residues in natural water environments has led to an urgent need for an environmentally friendly and highly efficient method to alleviate antibiotic contaminants. In this study, a Z-scheme CoMoO4/g-C3N4 binary heterojunction photocatalyst was synthesized to eliminate ciprofloxacin (CPF) contaminants in water. The obtained 20CoMO/CN samples showed a removal efficiency of 88% for CPF (20 mg/L) under visible light within 3 hours, which was 1.76 times and 2.09 times higher than that of CoMoO4 and g-C3N4, respectively. The formation of the Z-structure heterojunction promoted the separation of photogenerated electrons and holes, thereby improving the photocatalytic degradation efficiency of CPF.

Summary: In this work, a novel 1D/2D rod-sheet shape Cu3Mo2O9/g-C3N4 heterojunction photocatalyst was fabricated to reduce ciprofloxacin contamination in water. The results showed that the Cu3Mo2O9/g-C3N4 heterojunction photocatalyst sample with 20% Cu3Mo2O9 eliminated 83% ciprofloxacin (20 mg/L) within 3 hours, which was 2.59 and 1.84 times higher than bare Cu3Mo2O9 and g-C3N4, respectively. Furthermore, the catalyst maintained excellent stability after five repetitive photo-degradation processes. Finally, the photocatalytic mechanism of enhancing CPFX activity by Cu3Mo2O9/g-C3N4 hetero-junction photocatalyst was deduced.

Summary: This study developed a novel CoFe2O4/g-C3N4 heterojunction material for efficient degradation of ciprofloxacin pollutants in water, with sustained high degradation efficiency over multiple cycles. The enhanced photocatalytic activity of the composite material is mainly attributed to accelerated electron and hole separation and transfer through the formation of heterojunctions, which promotes the generation of more SO4 center dot- and center dot OH by stimulating PMS.

Summary: Novel graphene-like boron nitride (BN)/Bi3O4Br photocatalysts were synthesized controllably for the first time through a facile solvothermal method. Layer contact stacking between graphene-like BN and ultrathin Bi3O4Br was achieved with strong interaction. Dehalogenation and ultrathin structure of Bi3O4Br were designed to enhance visible light absorption and accelerate charge transfer, resulting in greatly improved photocatalytic performance. Graphene-like BN acted as a surface electron-withdrawing center and adsorption center, facilitating molecular oxygen activation. O-2(center dot-) was identified as the main active species during the degradation process.

Summary: Efficient heterojunction photocatalysts with spatial separation of photogenerated carriers are crucial to photo-catalysis. The unique carbonized polymer dots/ZnIn2S4 (CPDs/ZIS) Z-scheme heterojunction is designed to realize efficient spatial directional separation of photogenerated carriers and deliver enhanced photocatalytic performance in pollutant degradation. The CPDs generate more superoxide radicals to facilitate mineralization of organic pollutants and retain more holes for oxidation, while the Z-scheme migration mechanism of photogenerated carriers in the CPDs/ZIS composite preserves the original valence band potential of ZIS.

Summary: In this work, CuO was in situ generated on the Ti3C2Tx MXene surface by using electrostatic self-assembly. The in situ generation method successfully led to the dense formation of CuO on the MXene surface and even development of CuO lamellar structures, while the mechanical mixing method resulted in poor CuO distribution on MXene. The addition of I-Ti3C2Tx/CuO effectively reduced the pyrolysis peak temperature and increased the heat release in the thermal decomposition of TKX-50.

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.
