Summary: Researchers developed a structural engineering strategy to immobilize a molecular catalyst onto an ionomer, creating a composite material with a homogeneous catalysis environment inside ion-flow channels. This led to significantly improved mass transfer and turnover frequency due to 100% utilization of catalyst molecules, resulting in advantages of low overpotential and high fuel-cell power density in the homogeneous catalysis system.

Summary: It has been shown that atomically precise metal clusters, such as Pd1Au8(PPh3)(8)(2+), can play a crucial role in the catalytic efficiency of the Suzuki-Miyaura cross-coupling process. The cooperative effect between the central Pd atom and the peripheral Au atoms in the Pd1Au8(PPh3)(8)(2+) cluster has been identified as a key factor in controlling the cross-coupling reaction. By incorporating these clusters into a porous resin, a heterogeneous catalyst called Pd1Au8@Resin has been developed, which demonstrates enhanced catalyst recyclability and continuous performance in the cross-coupling reaction.

Summary: POMs, as a class of discrete anionic metal-oxygen clusters with tunable structure, exhibit super strong Bransted acidity, high proton mobility, and thermal stability, making them potential green alternatives to conventional homogeneous acid catalysts. Through design strategies such as functionalized cations, covalent interactions, non-precious metal support, and porous polymer framework, POMs-based heterogeneous catalysts have shown excellent catalytic performance in specific acid-catalyzed reactions.

Summary: In this study, DFT calculations were used to investigate the mechanisms of propene metathesis catalyzed by WOx/SiO2. The results showed that there are still many mechanisms of heterogeneous catalyzed metathesis reactions that are not well understood. The pseudo-Wittig mechanism was found to be the most favorable method for generating initial alkylidene active sites. The allylic and vinylic C-H activations are more difficult and require the reduction of surface sites to W(+4).

Summary: Ammonia (NH3) is crucial in agriculture and industry, but current production methods result in high energy consumption and CO2 emissions. Electrocatalytic nitrogen reduction reaction (NRR) offers a potential alternative, but faces limitations such as low ammonia yield and slow reaction kinetics. Atomically dispersed metal catalysts (ADMCs) provide opportunities for optimizing NRR performance due to their tunable electronic structure. This review summarizes the development of ADMCs, from homogeneous to heterogeneous phases, and discusses the challenges and perspectives for advanced NRR catalyst design.

Summary: Functionalizing inorganic particles with organic ligands is a common technique for heterogenizing organometallic catalysts. We studied the unexpected latency in catalytic activity of molecular platinum coordinated to silica nanoparticles functionalized with norbornene ligands. We found that this latency is related to ligand density, chemical structure of the norbornene, and nanoparticle topology. Additionally, we demonstrated the benefit of this latency for triggering curing of silicone elastomers.

Summary: Here, we report a manganese-catalyzed three-component coupling reaction for the synthesis of beta,beta-methylated/alkylated secondary alcohols. Our method efficiently constructs assembled alcohols with high chemoselectivity in moderate to good yields using a series of 1-arylethanol, benzyl alcohol derivatives, and methanol. Mechanistic studies suggest that the reaction proceeds via methylation of a benzylated secondary alcohol intermediate to generate the final product.

Summary: Hydrophobic coatings inspired by the lotus effect have gained popularity for their ability to solve various problems. The sol-gel method, utilizing silica, alumina, and titania, is explored as an environmentally friendly approach to produce water-based hydrophobic coatings. This study focuses on producing water-based hydrophobic coatings for cotton and polyester fabrics using a one-step sol-gel method. The coated fabrics exhibited improved hydrophobic properties, altered surface morphologies, and lower air permeability compared to uncoated fabrics. TEOS-PDMS coating provides a promising approach for enhancing the hydrophobic and surface properties of cotton and polyester fabrics.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
