Abstract ：
A 2D Mn-based MOF ([Mn4(PDI)2(DMF)7(H2O)]n (MOF 1)) (H4PDI = 5,5 '-(1,3,6,8-tetraoxo-1,3,6,8-tetrahydrobenzo[lmn][3,8]phenanthroline-2,7-diyl)diisophthalic acid) was synthesized. Visible light excited Mn-PDI unit in MOF 1 oxidizes NaSO2CF3 to generate center dot CF3 radical and enables MOF 1 to exhibit activity for trifluoromethylation of (hetero)arenes under visible light. The unusual stability of MOF 1 in the trifluoromethylation reactions can be attributed to its unique structure, which prevents it from corrosion by acid byproduct. The peeling of MOF 1 to ultrathin nanosheets or partial oxidation of Mn(II) to Mn(III) in MOF 1 led to MOL 1 and NB 1 with significant improved activity for trifluoromethylation reactions, demonstrating the important role of composition and morphology of a catalyst on its performance. The light initiated trifluoromethylation reactions over these Mn-based MOFs was applied to a variety of substrates. This study provides an efficient strategy for synthesis of trifluoromethylated compounds and highlights the potential of MOFs in light initiated organic syntheses.

Abstract ：
Photothermal catalytic N-acetylation of aniline has been a promising strategy to synthesize amides, which combined the advantages of thermal catalysis and photocatalysis. Herein, we demonstrate a high-performance strategy to synthesize amides catalyzed by the in-situ formed first-row transition-metal (Fe, Co, Ni, Mn et al.) complexes nanodots (TMC NDs) under solar light excitation without using noble metals or strong acids. The dualfunctional nitriles substrates acted as the ligands to coordinate with transition-metal salts affording photosensitive TMC NDs with high solar-to-thermal energy conversion efficiency. Intramolecular charge transitions reduced the energy barrier of nitriles activation by weakening C---N bond and triggered near-field temperature rise via the electron-phonon scattering non-radiative pathway. The reaction system exhibited good tolerance to different functional groups, affording a series of amide derivatives. Such a dynamic coordination reaction mode and the in-situ formed TMC NDs opens new avenues toward solar-heat conversion via photon-phonon coupling in the field of chemical synthesis.

Abstract ：
A AgBr-Ag2MoO4 heterojunction with high inactivation of E. coli under visible-light illumination was constructed. The crystal structure, morphology, elemental composition, and optical properties were characterized by TEM, SEM, XRD, XPS and DRS. The photocatalytic inactivation of E. coli by AgBr, Ag2MoO4, and AgBr-Ag2MoO4 was investigated. The results indicate that AgBr-Ag2MoO4 shows the best disinfection activity compared to AgBr and Ag2MoO4, with the E. coli being almost completely inactivated after illumination for 80 min. In addition, the cell structure of the bacteria is destroyed after visible-light irradiation in the presence of the catalyst. The UV absorption detection confirms that the bacterial protein leak and the concentration of nucleic acid in the solution also increase with the increase of the reaction time, indicating that the integrity of the bacterial cell membrane is damaged. The detection of ROS scavengers indicates that the reactive species (h(+), OH, e(-) and O-2(-)) play an important role in the inactivation of bacteria. The EPR tests confirm that the amount of OH is higher than that of O-2(-) during the illumination process, which is consistent with the results of the free-radical capture tests. The heterojunction of AgBr-Ag2MoO4 is beneficial for the separation of photogenerated electrons and holes during the illumination process, resulting in an improvement of the antibacterial properties.

Abstract ：
In a novel approach that capitalized on the differential solubility product (K-sp) of ZnSe and Ag2Se, a unique ZnSe/Ag2Se binary heterostructure was efficiently synthesized in situ. ZnSe/Ag2Se exhibited excellent antimicrobial efficiency under visible light. Incorporating Ag2Se into ZnSe significantly enhanced the photoelectric performance of the catalyst, greatly accelerating the separation of the photogenerated electrons in the system. Active species removal experiments determined that O-2(-) and H2O2 played crucial roles in photocatalytic antibacterial efficiency. Further investigation into the levels of cellular membrane peroxidation, bacterial morphology, and intracellular contents concentration revealed that during the photocatalytic antimicrobial process, reactive oxygen species initially oxidize phospholipids in the cell membrane, leading to damage to the external structure of the cell and leakage of the intracellular contents, ultimately resulting in bacteria inactivation. The photocatalytic antimicrobial process of ZnSe/Ag2Se fundamentally deviates from conventional methods, offering new insights into efficient disinfection and photocatalytic antimicrobial mechanisms.

Abstract ：
Mustard gas is a kind of erosive poison with great harm and used as a chemical weapon since World War. It has suggested that the photocatalytic technology is an effective method to eliminate it. Because the small difference in molecular structure between 2-CEES and Mustard gas, and the less toxic of 2-CEES, 2-CEES is often used as a simulator to evaluate the photocatalytic activity of catalysts. In this work, symbiotic mixture of Bi2WO6 and Bi6O6 (OH)(3)(NO3)(3)center dot 1.5H(2)O nanosheets doped with Mo (Mo-B-B) have been synthesized by a facile hydrothermal treatment. The samples were characterized by XRD, DRS, XPS, SEM, TEM, Raman, and PL. The photocatalytic activity of the samples was evaluated by measuring the degradation of 2-CEES under visible light irradiation. The results showed that the doped Mo reduce the Eg of bare symbiotic mixture and improve the separation efficiency of photo-generated carriers that is beneficial to photocatalytic activity. The optimum amount of doped Mo is 5% that exhibits the best activity for degradation for 2-CEES.

Abstract ：
Tailoring the surficial chemical environment of two-dimensional materials by organic modification is an effective way to optimize their catalytic behaviors. Herein, we present a dynamic coordination approach to improve the photocatalytic performance of ultrathin Co2CO3(OH)(2) nanosheets (u-CoCH) in NIR light (lambda > 780 nm) driven carbonylation reaction by using the reacting substrates (diamines) as the ligands. The coordination of diamines with surface Co2+ ions form a binuclear complex at the crystallographic planes of u-CoCH. The as-formed complexes can reduce the energy barrier of carbonylation reaction by weaking the N-H bond of the substrate on u-CoCH, and afford enhanced light response as well as the prolonged photogenerated electron lifetime. Together with the successful synthesis of a series of important structural motifs in pharmaceuticals and bioactive agents, the promoted photosynthesis reaction mode via in-situ formed surface complexes offers a model toward full-spectrum-solar-energy conversion in the field of chemical synthesis.

Abstract ：
Iodine(i) doped ZnO nanoarray films (ZnO/I-X) were prepared on a silicon wafer by the in situ growth method. The structure and morphology of the samples were tested by XRD, SEM, DRS. The hydrophobic properties were characterized by the water contact angle on the surface. The results show that the doped iodine extended the light absorption range of the ZnO nanofilm and the nanoarray film (ZnO/I-X) are super hydrophobic. The antimicrobial activity of iodine(i)-doped ZnO nanofilms towards E. coli under visible light illumination is much higher than that of the ZnO film. In addition, ZnO/I-3 exhibits the best antimicrobial activity.
