Summary: This study presents a functional hybrid photocatalyst system using a crystalline carbon nitride semiconductor, poly(triazine imide) lithium chloride (PTI-LiCl), and a CoCl2(qpy-Ph-COOH) catalyst for CO2 reduction. The optimized catalyst loading achieved high rates and selectivity for CO production, which were further improved by increasing the incident irradiance. Higher surface loadings were found to extend the lifetime of the molecular catalysts.

Summary: Photocatalytic hydrogen production is achieved by epitaxial growth of a van der Waals homojunction on an intralayer homojunction of carbon nitride, which enables controlled charge flow. The tandem internal electric field (IEF) in the integrated hybrid, composed of a lateral IEF along the intralayer homojunction and a vertical IEF within the VDW homojunction, facilitates efficient charge separations and mobilities, as well as intensified hydrogen reduction. The hydrogen evolution rate is significantly improved compared to in-planar homojunction and g-C3N4 benchmark, demonstrating the effectiveness of this strategy for robust photocatalysis.

Summary: This study reports a C3N5/C3N4 homojunction (AT-CN) catalyst as an efficient photocatalyst for PMS activation. The AT-CN catalyst possesses an interlaced band structure, high-efficiency charge transfer, and PMS activation capability. Experimental results show that the reaction rate constants of atrazine in the AT-CN/PMS/Vis system increased significantly compared to other systems, resulting in a high atrazine removal efficiency of 97% within 60 minutes (under pH = 3). DFT calculations were performed to analyze the band structure, charge density difference, PMS adsorption behavior, and activation pathways of AT-CN, providing insights for designing nonmetal homojunctions in the photo-activated PMS process.

Summary: A simple strategy of altering linker length in covalent organic frameworks (COFs) has been developed to fabricate efficient photocatalysts for hydrogen peroxide (H2O2) synthesis. By varying the linker length, three imine-linked COFs with similar structures but different amine linker lengths were successfully prepared. It was found that COFs with longer linkers exhibited higher H2O2 generation rates. This study provides a simple strategy for obtaining COF-based photocatalysts by facially varying linker lengths.

Summary: In this study, high-crystalline g-C3N4 samples, including K-CCN, Li/K-CCN, and Li/Na/K-CCN, were prepared via the molten salt strategy using pre-prepared BCN as a precursor. The Li/Na/K-CCN sample exhibited the highest photocatalytic hydrogen evolution rates and the highest apparent quantum yield compared to other CCN samples. The improved photocatalytic performance of Li/Na/K-CCN is attributed to the construction of type-II heterojunction and the institution of the built-in electric field between triazine-based CCN and heptazine-based BCN.

Summary: The spontaneous dissolution of 2D polytriazine imide (PTI) carbon nitrides in certain solvents is explored, revealing a complex and adaptable system. Multi-layered species are co-dissolved at high concentrations and can be further exfoliated to few- or single-layer species with the addition of water. The presence of intercalated lithium salts enhances the yield and improves the degree of exfoliation, with tunable delamination modifying the solutions' photoluminescent properties.

Summary: Controlled synthesis of phase-pure metal-organic frameworks (MOFs) is crucial, but little is known about the role of water in their formation. This study found that water is not only essential for the formation of Zr6O4(OH)4 clusters, but also plays a decisive role in the kinetics of dPCN-224 formation. The multidisciplinary approach used provides valuable insights for assessing and improving the reproducibility of Zr-MOF synthesis protocols, emphasizing the importance of understanding the role of water in Zr-MOF formation.

Summary: Tailored micromachines enable therapeutic applications in biological environments, but require sophisticated designs for controlled motion and targeted drug delivery. Covalent organic frameworks (COFs) offer new perspectives for light-driven microswimmers in biological media, such as intraocular fluids, for applications like retinal drug delivery. Two types of COFs, spherical TABP-PDA-COF sub-micrometer particles and nanoporous TpAzo-COF micrometer particles, are described as efficient visible-light-driven drug carriers in aqueous ionic and cellular media, with biocompatibility and the ability to load insoluble drugs for on-demand release. ICG dye loading in the COF pores enables real-time imaging and heat therapy for therapeutic applications.

The variable coordination geometry of Zr-oxo clusters and the conformational flexibility of the linker contribute to the outstanding diversity of Zr-based MOFs. The structural disorder of the MOFs expands the range of achievable topologies.

Summary: This study investigates bifunctional solar batteries through simulations and experiments, and provides design guidelines for operating a solar battery using 2D carbon nitride potassium poly(heptazine imide) as a photoanode. By proposing an optical design that focuses on light absorption in a charge collection layer within the photoanode, the study highlights the improved efficiency achieved by rear illumination for K-PHI layer thicknesses >200 nm. Enhancement strategies without modifying the photoactive layer are also proposed. Additionally, adapted Ragone plots demonstrate the potential for improved energy and charge output solely through illumination.

Summary: This study used a molecular catalyst integrated into a carbon nitride support to upgrade ethanol to n-butanol, which is one of the first examples of a supported molecular catalyst performing the Guerbet process. Initial studies using PTI with lithium or transition-metal cations imbedded in the support did not produce significant amounts of n-butanol. However, 59% selectivity for butanol (13% yield) was obtained at 145°C when using PTI-LiCl treated with [(Cp*)IrCl2] along with sodium hydroxide.

Summary: The removal of lead from commercialized perovskite-oxide-based piezoceramics has become an important topic in materials research due to legislation in many countries. Sn(II)-perovskite oxides, which have large spontaneous electric polarizations and can substitute for Pb(II) cations, have attracted interest. However, they have not been considered synthesizable due to their high metastability. In this study, a low temperature reaction at 300 degrees C between perovskite lead hafnate and SnClF resulted in the first complete Sn(II)-for-Pb(II) substitution, SnHfO3. The resulting compound exhibited high purity, crystallinity, and potentially reversible phase transformations and polarization between 130-200 degrees C.

Summary: The crystalline lithium oxonitridophosphate Li8+xP3O10-xN1+x was synthesized from P3N5 and Li2O in an ampoule. The compound has a triclinic crystal structure with distinctive complex anion species, including non-condensed P(O,N)(4) tetrahedra and P(O,N)(7) double tetrahedra connected by one N atom. The compound also exhibits mixed occupation of O/N positions, allowing for variation of anionic species. To characterize these motifs, complementary analytical methods were used. The compound displays significant disorder in its double tetrahedra structure, as observed in single-crystal X-ray diffraction. Additionally, the compound is a Li+ ion conductor with a total ionic conductivity of 1.2x10(-7) S cm 1 at 25 degrees C, and an activation energy of 0.47(2) eV.

Summary: Drug-induced liver injury (DILI) is a common cause of acute liver failure in the USA and Europe, but most cases can be recovered or prevented by discontinuing the offending drug. Recent research has found that peroxynitrite (ONOO-) can be used as a potential indicator for early diagnosis of DILI, and there is an urgent need to establish a method to detect and track peroxynitrite in DILI cases. In this study, a FRET-based nano fluorescent probe CD-N-I was developed, which showed high selectivity and sensitivity in detecting peroxynitrite. The probe successfully detected exogenous peroxynitrite in live cells and endogenous peroxynitrite in APAP-induced liver injury of HepG2 cells.
