Summary: Ce and C-S codoped mesoporous TiO2 nanocomposites were synthesized via a sol-gel method integrated with an evaporation-induced self-assembly approach. The synthesized samples were characterized and the results show that the codoping enhances the photocatalytic activity by narrowing the band gap, enhancing adsorption, trapping and transferring excited e-/h+ pairs, and suppressing recombination. The obtained C,S-TiO2/CeO2 materials have large specific surface areas and numerous pores, improving adsorption capability and providing mass and electron transfer channels. The photodegradation efficiency of RhB by C,S-TiO2/CeO2 is nearly 100% within 40 min, with a degradation efficiency 6.63 times that of undoped TiO2. The materials also exhibit excellent recoverability and stability.

Summary: BPA, an environmental estrogen, can be found in sewage, surface water, and even drinking water, posing a threat to human health. A visible light-driven N-F-TiO2/ZIF-8 photocatalyst was prepared and showed good degradation effect on BPA. The optimal dosage of N-F-TiO2/ZIF-8 was determined to be 10 mg with the highest photocatalytic activity (86.1%). The high adsorption capacity of ZIF-8 and the high separation rate of electron-hole pairs of N-F-TiO2/ZIF-8 contributed to the improved photocatalytic activity. The (OH)-O-center dot was confirmed as the main active substance for the photocatalytic degradation of BPA. The binary composite also exhibited good stability after multiple cycles of photodegradation reaction.

Summary: This study describes an aryl disulfide mediated C-F bond activation method to generate valuable gem-difluoroalky-lindoles. It is the first transition-metal-free redox-neutral C-F bond activation strategy and utilizes readily available commodity reagents under mild reaction conditions. The reaction allows for the use of various substituted indoles and alpha-fluoro-substituted esters. Additionally, this C-F activation method also enables the activation of trifluoromethylated arenes for the preparation of bis-benzylic gem-difluoromethylenes between indole and arene substructures, providing access to a unique chemical space.

Summary: The effect of g-C3N4 melting on the photocatalytic properties of g-C3N4/TiO2 composites was investigated using two commercially available TiO2 particles. Thorough thermal treatment at 350 degrees C for a certain period resulted in partial melting and phase fusion of g-C3N4, leading to improved contact between the components. This enhanced contact allowed for easier injection of photogenerated electrons and better charge carrier separation, enhancing the performance of the composites in bisphenol A degradation under visible-light illumination.

Summary: The modern agricultural system faces the challenge of meeting the increasing demand for food production caused by population growth and climate change. The use of nanotechnology in agriculture has gained significant interest for its potential to develop sustainable agricultural technologies and environmental remediation strategies. Nanotechnology involves the use of nanoparticles to fabricate novel materials and products with improved quality, playing a significant role in modern agricultural practices. However, the current physical and chemical processes involved in nanoparticle production are neither economical nor environmentally sustainable. Therefore, there is a need for green or biogenic nanoparticles obtained from plant, bacterial, fungal sources, or their metabolites, as a novel, sustainable, economical, biocompatible, and eco-friendly technology. This review focuses on the production and sources of biogenic nanoparticles and their implications in agro-ecosystems for crop productivity, soil health management, biocontrol, and environmental remediation, as well as the potential challenges in their development and implementation.

Summary: This study demonstrates the rapid dechlorination and relatively fast defluorination abilities of SNZVI nanoparticles synthesized via a modified post-sulfidation method, providing a new potential for groundwater remediation of fluorinated contaminants. The presence of Cl atoms in florfenicol increases the surface chemical reactivity for defluorination, highlighting the importance of understanding the mechanistic insights for developing new materials. The results suggest that SNZVI could be a promising technology for in situ groundwater treatment due to its enhanced reactivity and high efficiency compared to Fe-0-based technologies.

Summary: This study investigates the control of NO in marine ship exhaust and proposes a new method for NO2 removal based on hydrodynamic cavitation. The results show that hydrodynamic cavitation can delay but not prevent the production of NO, and the accumulation and decomposition of HNO2 are the primary causes of NO formation. Further experiments reveal that ClO2, H2O2, and Na2S2O8 can slightly increase the NO2 removal efficiency, while NaClO2 is less effective than water.

Summary: In this study, a plain strategy for fabrication of a novel composite ZnO/CuCo2O4 was designed, and it was applied as a catalyst for peroxymonosulfate (PMS) activation to decompose enrofloxacin (ENR) under simulated sunlight. The results showed that the ZnO/CuCo2O4 composite could significantly activate PMS under simulated sunlight, leading to the generation of more active radicals for ENR degradation. The study also evaluated the influences of various experimental factors on ENR degradation and proposed several reasonable ENR degradation pathways. The novel strategy provided by this study integrates state-of-the-art material science and advanced oxidation technology for wastewater treatment and environmental remediation.

Summary: This study explores the use of N-doped graphdiyne nanotubes (NGNTs) as a catalyst for metal-free PMS activation in water remediation. The NGNT-PMS system decomposes heterocyclic contaminants via electron-transfer-mediated nonradical oxidation, where metastable NGNT-PMS* complexes act as the primary oxidants. The NGNT-PMS system exhibits higher reaction rates compared to N-doped carbon nanotubes (NCNTs) and graphene oxide (NGO) systems, and also plays a crucial role in the cleavage of pyridine heterocycles and C-Cl bonds.

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.

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.
