Abstract ：
Supported noble metal cluster catalysts are typically operated under severe conditions involving switching between reducing and oxidizing atmospheres, causing irreversible transformation of the catalyst structure and thereby leading to permanent deactivation. We discovered that various platinum (Pt) precursors spontaneously disperse in a germanium-MFI (Ge-MFI) zeolite, which opposes the Ostwald ripening phenomenon, producing self-regenerating Pt/Ge-MFI catalysts for propane dehydrogenation. These catalysts reversibly switch between Pt clusters and Pt single atoms in response to reducing reaction and oxidizing regeneration conditions. This environmental adaptability allows them to completely self-regenerate over 110 reaction and regeneration cycles in propane dehydrogenation, and they exhibited unprecedented sintering resistance when exposed to air at 800 degrees C for 10 days. Such spontaneous metal dispersion in a Ge-MFI zeolite is a robust and versatile methodology for fabricating various rhodium, ruthenium, iridium, and palladium cluster catalysts.

Abstract ：
The shale gas revolution has shifted propylene production from naphtha cracking to on-purpose production with propane dehydrogenation (PDH) as the dominant technology1, 2, 3, 4, 5, 6, 7, 8-9. Because PDH is endothermic and requires high temperatures that favour sintering and coking, the challenge is to develop active and stable catalysts1, 2-3 that are sufficiently stable10,11. Zeolite-supported Pt-Sn catalysts have been developed to balance activity, selectivity and stability12,13 and more recent work documented a PDH catalyst based on zeolite-anchored single rhodium atoms with exceptional performance and stability14. Here we show for silicalite-1 (S-1) that migration of encapsulated Pt-Sn2 clusters and hence agglomeration and anchoring within the zeolite versus agglomeration on the external surface can be controlled by adjusting the length of the S-1 crystals' b-axis. We find that, when this axis is longer than 2.00 mu m, migration of Pt-Sn2 monomers during PDH results in intracrystalline formation of (Pt-Sn2)2 dimers that are securely locked in the channels of S-1 and capable of converting pure propane feed to propylene at 550 degrees C for more than 6 months with 98.3% selectivity at 91% equilibrium conversion. This performance exceeds that of other Pt-based PDH catalysts and approaches that of the Rh-based catalyst. Although synthesis requirements and cost are at present prohibitive for industrial use, we anticipate that our approach to controlling the migration and lockup of metals in zeolites may enable the development of other noble-metal catalysts that offer extended service lifetimes in industrial applications15, 16-17.

Abstract ：
In order to gain insight into the influence of SiO2 support particle size on the vacuum residue (VR) slurry-phase hydrocracking performance of Fe-based catalysts, a series of FeZn/SiO2 catalysts with varying SiO2 particle sizes were prepared. Characterization results show that the surface area and pore volume of the FeZn/SiO2 catalysts increase with the reduction of SiO2 particle sizes. The metals Fe and Zn species on FeZn/SiO2-S catalyst are more readily reducible via H2-TPR analysis. Notably, FeZn/SiO2-S catalyst presents higher metal dispersion and a greater degree of sulfurization compared to the other catalysts by XRD and XPS. Hydrocracking results demonstrate that the FeZn/SiO2-S catalyst achieves the lowest coke and gas yields (11.9 wt% and 0.4 wt%), respectively, and the highest VR conversion among these catalysts. The superior performance of the FeZn/SiO2-S catalyst in VR slurry-phase hydrocracking is ascribed to its enhanced hydrogenation activity, deriving from the higher dispersion and sulfurization of metals species. This suppresses the aggregation of polycyclic aromatic hydrocarbons in VR and the over-cracking of intermediate products. Additionally, the increased mesopore associated with smaller SiO2 particles facilitates to the diffusion of large VR molecules, further promoting the hydrocracking reaction.

Abstract ：
Hierarchical SAPO-11, featuring both micropore and mesopore channels, demonstrates an outstanding performance in high-octane gasoline production. In this work, we propose an economic and effective approach to directly fabricate hierarchical SAPO-11 molecular sieve from natural kaolin, eliminating the need for mesoporogens. The systematic characterization results show that the kaolin-derived SAPO-11 possesses abundant micro-mesoporous structure and more Br & oslash;nsted (B) acid sites on the external surface in contrast with the conventional SAPO-11 prepared employing silica sol as silicon source as well as SAPO-11 synthesized with the assist with of poly(ethylene oxide)-block-poly(propylene oxide)-blockpoly(ethylene oxide) (F127). The analysis of the formation process reveals that the kaolin not only provides silicon source for the SAPO-11 crystal growth, but also offers confined environment for crystal growth along the preferential orientation, resulting in the generation of the microporous and mesoporous structure. Benefiting from these unique properties, the kaolin-derived Pt/SAPO-11 exhibits considerably improved selectivity for di-branched C8 isomers in n-octane hydroisomerization. (c) 2024 The Authors.

Abstract ：
A low-cost and process-intensified synthesis approach of SSZ-35 zeolite via a seed-assisted method is presented. This approach involves the development of a relatively inexpensive template and the application of seeds to minimize crystallization time and template consumption. Herein, N-Ethyl, N-methyl 2,6-cis-dimethylpiperidinium hydroxide (EMDMPOH) is selected as a template to synthesize SSZ-35 zeolite, and a simplified and optimized scheme for the preparation of such a template is proposed. Specially, the high-purity EMDMPOH is prepared by a sequential alkylation of 2,6-dimethylpiperidine with iodoethane and iodomethane, followed by ion exchange. By employing a seed-assisted strategy, the synthesis process of SSZ-35 zeolite is intensified, resulting in a significant reduction in crystallization time from 7 d to 75 h. Systematic characterizations reveal that the synthesized SSZ-35 zeolite has smaller crystals and larger specific surface area in comparison with the reference sample, leading to enhanced selectivity in n-octane hydroisomerization. Moreover, the cost accounting analysis shows a notable decrease in the synthesis cost of SSZ-35 zeolite by using the synthesis route that combines the simplified process for preparing the template and the reduced amount of template.

Abstract ：
This study investigates the effect of mechanical vibrations on the pneumatic conveying behavior of nano/micro particles. The minimum pickup velocity (Upu), at which particles are entrained, is experimentally determined for five types of particles (from 20 nm to 275 mu m). Vertical vibrations reduce the Upu for both nano- and microparticles, but the response to vibration differs between large, non-cohesive particles and smaller, more cohesive ones. Larger, non-cohesive particles require weaker vibrations to reduce Upu, while stronger vibrations are needed for nano- and low-micron particles, which are not transported individually but form large agglomerates over 100 mu m, and exhibit irregular and pitted surfaces. A review of current models reveals a lack of a reliable method for accurately predicting the pickup velocities of particles in the nano-to-micro range. To address this, a modified three-zone correlation is proposed to better predict the pickup behavior of nano- and micro-particles under vibration.

Abstract ：
Single-crystalline hierarchical zeolites are highly promising for petrochemical and green chemistry applications, but their synthesis traditionally relies on halogen- and/or nitrogen-containing organic templates whose removal through calcination poses serious environmental pollution. Herein, we present a green, halogen- and nitrogenfree approach for single-crystalline hierarchical ZSM-5 zeolite synthesis using dextran as a bifunctional template. Theoretical calculations and experimental results reveal that dextran can induce the transformation of partial four-membered rings into five-membered rings during crystallization, and interact strongly with Si-OH and/or Al-OH groups through hydrogen bonding. Acting as a structure-directing agent, dextran not only stabilizes the five-membered rings formed in the precursor, but also facilitates the construction of the mobil five (MFI) zeolite framework through the interactions between the hydroxyl/alpha-CH groups and Si/Al species. Additionally, dextran aids in the directional arrangement of nanocrystals, and serves as a space-filling agent within the mesopores during synthesis. The resulting single-crystalline hierarchical ZSM-5 zeolite exhibits superior catalytic performance in low density polyethylene pyrolysis and methanol-to-propylene reactions. This work provides a sustainable and scalable strategy for synthesizing advanced zeolite nanomaterials, with broad implications for catalysis and green chemistry.

Abstract ：
For traditional strategies to construct SO2 and H2O co-resistant systems in low-temperature NH3 selective catalytic reduction (NH3-SCR) catalysts, the primary challenge lies in mitigating the partial loss of redox activity at active sites. Herein, we present an approach to construct a protective system based on interface engineering principles, effectively safeguarding Cu active sites in ZnO/FeCu-SSZ-13 under SO2 and H2O exposure. The core innovation stems from the creation of a strong interface effect originated from Zn-O-Al bonds formed between ZnO and the framework Al on the FeCu-SSZ-13 surface. This interface effect can regulate the electronic structure of Zn[sbnd]O bonds on ZnO component, producing abundant basic sites around the Cu active sites, enabling the preferential adsorption of SO2 and its oxidation into ZnSO4, thereby virtually eliminating the redox ability loss of Cu active sites. As a result, ZnO/FeCu-SSZ-13 achieves exceptional low-temperature NH3-SCR performance, maintaining over 90 % NOx conversion even in the presence of SO2 and H2O. Our work opens a new avenue for developing low-temperature NH3-SCR catalysts with desired SO2 and H2O resistance, offering valuable insights for advancing catalytic performance in challenging reaction conditions. © 2025 Elsevier B.V.

Abstract ：
Adsorptive separation, which relies on the size, polarity, and affinity of guest molecules, is an efficient, eco-friendly, and cost-effective method. Zeolite-based adsorbents, known for their uniform pore size and regenerability, have exhibited exceptional performance in many challenging adsorption processes, such as the separation of n-paraffin/i-paraffin and xylene isomers. Ion exchange, as an essential piece in the fabrication of zeolite-based adsorbents, significantly affects overall performance. In this review, we survey the recent key developments and issues within ion exchange research of zeolite-based adsorbents, including the solution pH, solution concentration, ion-exchange cycles, ion-exchange temperature, ion-exchange time, calcination temperature, and discuss the mechanisms of their influence on zeolite adsorption. This review also elaborates on the negative effects of improper ion exchange on incomplete cation exchange, cation migration, collapse of the zeolite structure, and blockage of zeolite pores. Other parameters that lack research but have been proven to affect ion exchange are also mentioned. We hope to generate interest in the wider community and encourage others to make use of ion exchange in tackling challenges of adsorption separation science and engineering.
