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.
