Summary: A mesoporous silica stabilized Pd-Ru@ZIF-8 nanoreactor was designed and showed superior performance in selective semi-hydrogenation of phenylacetylene to styrene, with high conversion and selectivity. The synergistic effect of single-site Pd and Ru anchored into the ZIF-8 framework contributed to the enhanced catalytic activity.

Summary: Two-dimensional metal-organic framework nanosheets (2D MOF NSs) have emerged as durable and efficient electrocatalysts for the hydrogen evolution reaction (HER) due to their ultrathin thickness and large surface area. However, these nanosheets are typically less conductive and tend to aggregate, which hampers their electrocatalytic efficiency. In this study, a simple and unique strategy is proposed to create electrocatalysts with multilevel nanostructures by growing carbon nanotubes (CNTs) in situ from 2D Ni-MOF NSs through calcination. The resulting catalyst exhibits enhanced HER performance, and a two-electrode system utilizing this catalyst shows good electrocatalytic activity for overall water splitting.

Summary: The study prepared Fe-ISAs/H-CNs electrocatalysts with higher half-wave potential and exceptional kinetic current density, exhibiting better stability and tolerance to methanol crossover in alkaline media compared to commercial Pt/C catalysts and most previously reported non-precious-metal catalysts. The superior performance was attributed to the hollow carbon nanocages and the Fe single atoms with the Fe-N-4 configuration.

Summary: Mesopore-confined cobalt catalysts are utilized to regulate diameters and chirality of single-walled carbon nanotubes through CO disproportionation. Different synthetic strategies affect the growth of SWCNTs with varying diameters and distributions, while Raman and photoluminescence excitations correlate with the properties of SWCNTs. Informative X-ray absorption experiments reveal the effects of H-2 pretreatment on the cobalt catalysts. The CO disproportionation reaction enables suitable confined growth of SWCNTs via co-condensation of cobalt catalysts into mesoporous materials.

Summary: In this study, we synthesized and scaled up Ru catalysts using high porosity MOF templates grown on graphitic carbon supports via solvothermal synthesis. Thermal treatment of the MOF resulted in well-dispersed Ru nanoparticles that were fully stabilized by in-situ graphitization of the surrounding carbon. The resulting catalyst showed significant improvement in activity for low-temperature NH3 synthesis, and the production of catalysts was scaled up from 1 g per batch to 200 g per batch.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. 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.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
