Summary: The design and construction of heterojunction photocatalysts, especially using metal-organic frameworks (MOFs), is found to enhance photocatalytic performance. In this study, a MOF-902(Ti) and BiOCl heterojunction (TB) was developed for efficient degradation of antibiotic tetra-cycline (TC) under visible light. The TB heterojunction exhibits superior photocatalytic activity compared to MOF-902(Ti) and BiOCl, attributed to improved visible light response, increased surface area/pore volume, enhanced charge carrier separation and transfer. Reactive species trapping confirms the involvement of center dot O2-, e-, and h+ in the TC photodegradation. A possible mechanism for the enhanced photocatalytic activity of TB heterojunction is proposed.

Summary: In this study, the enhanced photocatalytic activity of delta-Bi2O3 nanoparticles under visible light irradiation was demonstrated. Nanostructured delta-Bi2O3 with a size of less than 50 nm was successfully synthesized by a simple chemical precipitation method. The delta-Bi2O3 nanoparticles showed superior activity towards various pollutants under visible light, which can be attributed to their microstructure and the presence of oxygen vacancies in the defective fluorite structure. The findings of this work provide a new approach to enhance the photocatalytic performance of delta-Bi2O3 without the need for additional compounds.

Summary: An original strategy of heteroatom (P and S) doping was reported to manipulate ORR selectivity of N-doped hollow mesoporous carbon spheres (N-HMCS). Heteroatom doping can modulate the electronic structure and the proportion/configuration of doped N in N-HMCS, as well as regulate the pathway of ORR. The presence of rich-graphitic N sites and electron-rich C-P bond domains in N,P-HMCS act as electron donors, making *OOH more unstable and easier to desorb into H2O2. Conversely, the introduction of highly electronegative S hinders the desorption of *OOH through a strong interaction with the electron-deficient C-S bond domain, leading to the breakage of the O-O bond and promoting four-electron ORR along with the rich-pyridinic N receptor site. The activity and kinetics mechanism of the reaction show a positive correlation with the proportion of graphitic N, indicating that graphitic N is the primary active site with a much faster electron transfer capacity.

Summary: We propose that universal anomalies near phase transitions may originate from geometric phase effects. In our multi-level quantum model, quantum interference induced by the geometric phase can alter the relaxation times of excited states at phase transition points. Furthermore, by introducing a phase shift of p, we can decouple the excited state from the ground state, extending the relaxation time of qubits for quantum computing.

Summary: Water is considered an inhibitor of CO oxidation. The practical application of CO oxidation is investigated by coupling Au nanoparticles and defective CuO to form metal-support interactions and oxygen vacancies. The introduction of Au creates new CO adsorption sites, solving the competitive adsorption problem with H2O and O2. The coupling of metal-support interactions and oxygen vacancies enhances the catalyst's ability and oxygen activation and migration. Au-CuO exhibits stable CO oxidation at room temperature under humid conditions. Theoretical calculations confirm the competitive adsorption and the influence of metal-support interactions and oxygen vacancies on catalyst performance, explaining the mechanism of water resistance in CO catalytic oxidation.

Summary: In this study, the photocatalytic activity of bismuth tungstate (Bi2WO6) for the degradation of perfluoroalkyl substances (PFAS) was enhanced by partially substituting Zn2+ for Bi3+ in the crystal lattice. The partial substitution of Zn2+ influenced the crystal structure, optical properties, and morphology of the nanoparticles of Bi2WO6, resulting in enhanced photocatalytic activity. The photodegradation of PFAS was mainly attributed to the photo-excited holes and superoxide radicals generated during the process.

Summary: In this work, dual-substitution of Al3+ and/or Mg2+ for Ta5+ in BaTaO2N is used to improve its photocatalytic activity. The dual-substitution leads to a redshift in the optical absorption edge and an increase in the optical bandgap energy of BaTaO2N. The photocatalytic activity is enhanced, with higher O-2 evolution observed in samples with higher Mg2+ concentration and higher H-2 evolution rate observed with increased Al3+ concentration. Density functional theory calculations suggest that the Al3+-Mg2+ (co)substituted BaTaO2N photocatalysts have lower effective masses of electrons and show promising potential for visible-light-induced water splitting.

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.
