Summary: In this study, an in-situ synthesis route was proposed to fabricate 0D/2D CuFe2O4/MXene heterojunctions, which enhance charge transfer during photocatalytic reactions. The Z-scheme mechanism of the heterojunctions was proposed to explain the improved charge separation efficiency through the transfer of photoinduced holes from MXene to CuFe2O4. The heterojunctions exhibited superior activity in the selective photocatalytic oxidation of benzyl alcohol.

Summary: In this study, a 0D/2D In2O3/Bi2WO6 Z-scheme heterojunction was successfully constructed. The In2O3 nanoparticles were immobilized on the surface of the Bi2WO6 nanosheets using a simple hydrothermal-calcination method. The crystal structure and photoelectrochemical properties of the samples were characterized. The 15% In2O3/Bi2WO6 (IB-15) exhibited optimal photocatalytic performance in the degradation of tetracycline and oxytetracycline under visible-light irradiation, and the possible degradation pathways of tetracycline were identified using LC-MS. Superoxide radicals and photogenerated holes were found to be the predominant active species for the degradation, and a possible photocatalytic mechanism was proposed. The significant improvement in photocatalytic property was attributed to the unique Z-scheme heterojunction with a 0D/2D architecture, which facilitated the rapid separation of photo-excited carriers and extended the absorption spectrum.

Summary: A novel visible-light-driven 0D/2D CdZnS/SnIn4S8 heterostructure was successfully prepared by growing 0D CdZnS quantum dots on the surface of 2D SnIn4S8 nanosheets. The heterojunctions exhibited excellent photocatalytic activity for the degradation of tetracycline and rhodamine B, as well as reducing H2O to hydrogen, due to their unique dimensional coupling structure and high mass transfer rate. The uniformly and intimately contacted interface between CdZnS quantum dots and SnIn4S8 nanosheets played a crucial role in enhancing the photocatalytic capability.

Summary: Ti3C2/Bi12O17Cl2 composites were prepared by a simple ultrasonic composite method and their successful preparation was confirmed by XRD, TEM, XPS, BET, and DRS analysis. The Ti3C2/Bi12O17Cl2 composite with a Ti3C2 mass fraction of 2% exhibited a degradation rate constant of 0.17406 min-1 for Rhodamine B (RhB), which was 5.5 times higher than that of Bi12O17Cl2 (0.03186 min-1). After 5 cycles of experiments, the degradation rate remained at 93.8%. The introduction of Ti3C2 promoted the migration of photogenerated electrons and holes over Bi12O17Cl2, leading to significantly improved photocatalytic activity of Ti3C2/Bi12O17Cl2 composites. A highly active photocatalyst was proposed.

Summary: The key to the carrier transfer separation conditions in heterojunction composite photocatalysts lies in the intimate contact interface. By enhancing the electron transfer rate between catalysts during photocatalytic hydrogen production, and designing the close contact of 0D/2D heterojunction, the photocatalytic hydrogen production activity of the composite catalyst can be greatly increased.

Summary: The construction of a heterojunction composed of zero-dimension nickel sulfide nanoparticles and cadmium sulfide flowers has led to significant improvement in photocatalytic H-2 production under visible light irradiation. The obtained nano composite with 25% NiS exhibits remarkable performance with an H-2-production rate 69.6 times higher than that of pristine CdS. The enhanced photocatalytic activity is mainly attributed to the intimate contact and efficient separation of photoinduced carriers across the interface.

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.
