Summary: This study reports a series of single and multiple (bi-varietal and tri-varietal) pillar-layered metal-organic framework (MOF) thin films (surface-coordinated MOF thin films, SURMOFs) with high lattice mismatch. The SURMOFs were successfully grown on the substrate surfaces with preferred [001]-orientation using a liquid-phase epitaxial (LPE) layer by layer pump method. The results show that the representative bi-varietal SURMOF with large lattice mismatch has different adsorption behavior from single SURMOFs, providing a new strategy to achieve tuning of the adsorption kinetics performance in sensing applications.

Summary: ZIF-8 membranes prepared on polyamide substrates demonstrated successful separation of acetylene/methane and acetylene/carbon dioxide mixtures with separation factors of 12.1 and 1.8 respectively. The separation mechanism for C2H2/CH4 is attributed to acetylene affinity and molecular sieving, while C2H2/CO2 separation is related to thermodynamic factors. This study marks the first successful separation of C2H2 from CH4 and CO2 by MOF membranes.

Summary: This paper identifies the electrochemical properties of individual facets of anisotropic layered conductive metal-organic frameworks (MOFs) and applies them to the electrochemical detection of neurochemicals. The basal plane of the MOFs proves more selective and sensitive for dopamine detection than the edge sites. The study suggests that the improvement in performance and selectivity is related to the adsorption characteristics of analytes on different facets of the MOF interfaces.

Summary: This study successfully synthesized a magnetic guanidyl-functionalized MOF hybrid coating with multiple affinity sites for selective and efficient enrichment of global phosphopeptides. The coated MOF nanospheres exhibit large surface area, good superparamagnetic property, stability, and size-exclusion effect, making them a specific adsorbent for phosphopeptide analysis with satisfactory selectivity, great detection sensitivity, and rapid magnetic separation. The application of this coating in capturing multi and mono-phosphopeptides from human saliva and serum demonstrates its great potential in identifying low-abundance phosphopeptides from complex biological samples by mass spectrometry.

Summary: Metal-organic frameworks (MOFs) with highly modulable structures and components have the potential to be used as tunable luminophores. In this study, two MOF luminophores based on Cd(II) ions, 1,3,5-tri(4-pyridinyl)benzene (TPB), and 1,4-dicarboxybenzene (H2BDC) were constructed. The fluorescence properties and structure of MOFs were investigated, showing that the fluorescence of MOF-2 can be regulated by the amount of anthracene feeding.

Summary: The formation of porous and non-porous polymorphs in different solvents is shown to depend on a solvophobic effect driven by dispersion interactions, with weak dispersion interaction facilitating porous packing. Dense packing is a universal tendency of organic molecules in the solid state, but a solvophobic approach allows for the successful synthesis of porous polymorphs.

Summary: The self-assembled behaviors between calixpyridinium and two pyrenesulfonate guests were studied, revealing differences in morphology, properties, and iodine capture capability. PS guests formed spherical aggregates, while PyTS guests formed rodlike aggregates. The calixpyridinium-PyTS aggregates showed strong green fluorescence and had the ability to adsorb iodine in both liquid and vapor phases, whereas the calixpyridinium-PS aggregates could not capture iodine. The diverse capabilities were determined by the self-assembled structure at the molecular level.

Non-thermal plasma approach shows potential as a sustainable and efficient alternative to traditional thermocatalytic routes. The combination of a catalyst and non-thermal plasma has been found to improve the selectivity and conversion of CO2 into desired products.

Summary: In this study, a BiOBr/Bi2WO6 S-scheme heterojunction with intimate interfacial contact was synthesized by a one-step hydrothermal method. The nanoflower morphology and the concentration of surface oxygen vacancies (SOVs) were regulated to enhance CO2 capture ability and charge transfer efficiency. The heterojunction exhibited excellent photocatalytic CO2 reduction activity without sacrificial agent and cocatalyst, surpassing most reported photocatalysts.

Summary: Iron phthalocyanine/carbon nitride (FePc/CN) hetero-junction nanosheets were prepared using calcination method and exhibited excellent activation of peroxydisulfate (PDS) for tetracycline (TC) degradation under visible light. The FePc/CN-6 heterojunction showed significant improvement in degradation rate compared to CN and FePc due to the synergistic effect of photocatalysis and PDS activation. The construction of intimate interface via pi-pi conjugation enhanced charge separation and transfer, resulting in enhanced PDS activation and photodegradation.

Summary: In this study, we identified two new titanium sites in the environmentally friendly titanium-containing zeolite catalyst, TS-1. These sites, namely penta-coordinated Ti(OH)2(OSi)3 and hexacoordinated Ti(OH)4(OSi)2, were characterized using UV resonance Raman spectroscopy and density functional theory calculations. The hexacoordinated Ti(OH)4(OSi)2 site exhibited higher catalytic activity compared to the penta-coordinated Ti(OH)2(OSi)3. Additionally, the catalytic activity of Ti(OH)4(OSi)2 was found to be approximately 8.7 times higher than that of the known tetra-coordinated framework Ti(OSi)4 sites, indicating its high activity in propylene epoxidation to propylene oxide.

Summary: Ultrafast synthesis of nanocrystal assembled ZSM-48 spheres and regulation of acidity were achieved in just 1.5 hours using a pretreated-seed-solution-assisted strategy. The resulting product demonstrated excellent performance as an acid support in hydroconversion reactions of long-chain alkanes. By altering the introduction sequence of aluminum source, it was found that the crystallization behavior and acid properties of the ZSM-48 zeolite varied significantly, leading to differences in catalytic activity and selectivity for n-C-12 hydroisomerization.

Summary: In this study, an in situ synthesized K-Co2C catalyst was developed for CO2 hydrogenation, achieving a selectivity of 67.3% for C2+ hydrocarbons. Experimental and theoretical results showed that CoO transformed into Co2C, and the stability of Co2C depended on the reaction atmosphere and the K promoter. The formation of surface C* species was facilitated by the co-action of K promoter and H2O, while the adsorption of C* on CoO was enhanced by the K promoter. The addition of H2O extended the lifetime of K-Co2C from 35 hours to over 200 hours.

Summary: A photocatalyst TiO2/Ti-BPDC-Pt with a self-grown TiO2/Ti-MOF heterojunction, selectively anchored high-density Pt single-atomic cocatalysts on Ti-BPDC, achieves photocatalytic hydrogen evolution. The intimate heterojunction efficiently separates electrons and holes in a direct Z-scheme, and Pt is selectively anchored on Ti-BPDC in the form of single atoms. The tailored TiO2/Ti-BPDC-Pt exhibits significantly enhanced activity compared to other TiO2- or MOF-based catalysts, showing the importance of the balance of two simultaneously exposed domains of heterojunctions.

Summary: ZSM-5 nanosheets show promise as catalysts for diffusion-controlled catalytic reactions. In the alkylation of benzene with methanol, nanosheets with a thickness of 30 nm exhibit higher benzene conversion, xylene selectivity, and methyl selectivity, as well as a longer lifetime and lower ethylbenzene selectivity compared to nanosheets with a thickness of 300 nm. This is attributed to the shorter straight channel length, larger specific surface area, and increased mesopore volume of the nanosheets, which enhance the diffusion of reactants and products and decrease coke formation.

Summary: This work investigates the effect of potassium (K) promoter on the carburization and oxidation of iron-based catalysts during CO2 hydrogenation. The addition of K enhances CO2 adsorption, promotes the reaction with hydrogen, and accelerates the carburization of iron phases. In addition, K prevents the oxidation of Fe5C2 during CO2 hydrogenation. The optimized iron-based catalysts exhibit high catalytic activity for CO2 conversion to olefins and long-chain hydrocarbons.
