Summary: The impact of NH4F etching on the textural and catalytic properties of TS-1 was investigated. It was found that NH4F etching resulted in the generation of larger mesopores and a reduction in the coherent crystal size (CCS). The conversion kinetics of methyl-phenyl sulfide (MPS) were significantly influenced by the textural properties of the catalysts.

Summary: Hierarchical MOR-type zeolites were synthesized using CTAB as a porogen agent, showing higher porous volume and BET surface area. Increasing CTAB concentration led to higher mesoporous volume and BET surface area, while preserving zeolite micropores. By reducing the aluminum content in the synthesis gel, the Si/Al ratio of the zeolite framework can be increased. These synthesized hierarchical MOR-type zeolites exhibited improved catalytic activity for n-hexane cracking compared to large zeolite crystals obtained without CTAB.

Summary: This study proposes an interface/substrate engineering approach to improve CO2-splitting and thermochemical energy conversion. By coating CuFe2O4 and Co3O4 layers on SiC, the reactive surface area of the material is increased, and inter-layer oxygen exchanges are facilitated by a stable SiC-Co3O4 layer. The remarkable thermochemical performances are attributed to the synergistic effect between CuFe2O4 and Co3O4 layers and stoichiometric reaction characteristics.

Summary: In this study, an in situ and on-demand strategy for hydrogen peroxide (H2O2) generation was developed using a cascade water electrolysis and heterocatalysis system. The system achieved a high H2O2 generation rate of 0.85 mol L-1 h(-1) g(Pd)(-1) by utilizing efficient zeolite-encaged ultrasmall Pd catalysts. The confinement effect of zeolites not only promoted the formation of highly dispersed metal species for H2O2 generation, but also inhibited H2O2 decomposition, increasing the production yield of H2O2. The findings provide a new avenue for H2O2 generation through a highly efficient electrolysis-heterocatalysis system using zeolite-supported metal catalysts.

Summary: The investigation on rhodium-containing silicalite-1 zeolites using the HET-PHIP NMR technique reveals that the supported rhodium species and zeolite structure play crucial roles in molecule polarization and signal enhancement. Intensive polarized signals are observed on self-pillared silicalite-1 nanosheets supported rhodium catalyst, while silicalite-1 nanocrystals supporting large rhodium nanoparticles show lower activity for the generation of polarization. Single-atom rhodium encaged in silicalite-1 nanocrystals exhibits high hydrogenation activity but low observed polarization generation efficiency, indicating the critical role of the interactions between polarized molecules and micropore structures in attenuating the polarization.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
