Summary: Gold nanoparticles dispersed on mordenite efficiently catalyze the selective oxidation of methane to methanol by molecular oxygen in aqueous medium in the presence of carbon monoxide. The methanol productivity reaches 1300 mu mol g(cat) (-1) h(-1) or 280 mmol g(Au) (-1) h(-1) with 75% selectivity at 150 degrees C, outperforming most catalysts reported under comparable conditions. Both hydroxyl radicals and hydroperoxide species participate in the activation and conversion of methane, while the lower affinity of methanol on gold mainly accounts for higher methanol selectivity.

Summary: In this study, a novel non-noble-metal-catalyzed oxidation/cyclization reaction has been developed to synthesize diversely functionalized lactams in moderate to good yields with excellent diastereoselectivities, without the production of typical cyclopropanation products. Furthermore, the combination with another chemical reaction allows for the high diastereo- and enantioselective synthesis of chiral gamma-lactams containing three contiguous stereocenters. Density functional theory calculations suggest that this reaction possibly involves a carbon cation or proton transfer process.

Summary: Using Au/TiO2 as photocatalyst, glycerol oxidation was achieved in a non-pressurized reactor with borate additives. The activity and selectivity of the reaction depended on Au loading, borate concentration, and solution pH. Borate additives not only coordinated and protected oxidized intermediates, but also enhanced the production of superoxide radicals, promoting the formation of C3 products. Under AM 1.5 G irradiation for 4 hours in pH 12 solution, a glycerol conversion rate of 94% was achieved, with C3 product selectivity of 58% on liquid-phase basis and 37% on carbon basis. This finding has implications for future photocatalytic biomass valorization catalyst design, emphasizing the need for balanced oxidative power to guide reaction pathways.

Summary: Light-driven primary amine oxidation to imines integrated with H2 production presents a promising means to simultaneous production of high-value-added fine chemicals and clean fuels. A spatial decoupling strategy is proposed to overcome the limitations of poor charge separation and uncontrolled hydrogenation. The CoP@ZnIn2S4 photocatalyst exhibits directional and ultrafast carrier separation, leading to significantly higher production rate and selectivity for the photoconversion of benzylamine to N-benzylbenzaldimine.

Summary: This work demonstrates efficient in situ surface-enhanced Raman spectroscopy (SERS) tracing of the highly representative SnO2-ethanol gas sensing using Au@SnO2 nanoparticles (NPs), providing experimental elucidation of the specific gas sensing mechanism. The in situ SERS evidence suggests that the sensing follows a Mars-van Krevelen mechanism rather than the prevailing adsorbed oxygen (AO) model. This mechanism is also observed in sensing other gases based on the Au@SnO2 NPs, showing its universality.

Summary: The study found that mesoporous Co3O4 catalyst exhibited excellent catalytic activity for the selective oxidation of aromatic alkanes, particularly the conversion of ethylbenzene to acetophenone with a conversion rate of 42% and a selectivity of 90% at 120 degrees Celsius. Furthermore, it was discovered that mCo(3)O(4) followed a unique catalytic pathway of direct oxidation from aromatic alkanes to aromatic ketones, as opposed to the conventional stepwise oxidation to alcohols and then to ketones. This implied that mCo(3)O(4) had a higher kinetic favorability for the direct oxidation of ethylbenzene to acetophenone compared to non-selective oxidation on commercial Co3O4.

Summary: By selectively cleaving the C-O bonds in CH3O* intermediates instead of the metal-O bonds, the formation of peroxidation products can be significantly prevented, thus modulating the conversion pathway of methane. This method allows methane to be converted to methanol with a higher rate (325.4 mu mol g(-1) h(-1)) and selectivity (87.0%) under room temperature and atmospheric pressure without the need for external oxidants.

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.
