Summary: A new hybridization strategy of Fe/Cu bimetal and silica-based mesoporous molecular sieve MCM-41 has been proposed to improve the performance of Fe-0 in removing Cr (VI) from water. The results showed that the two-dimensional mesoporous structure of MCM-41 can provide skeleton support for Fe-0 and overcome aggregation bottleneck, leading to a high Cr(VI) removal rate of 98.98% after 40 minutes.

Summary: We report the synthesis, characterization, and catalytic activity of a highly efficient and reusable silica-based catalyst MCM-41@CP@PAL@Cu. The catalyst was prepared by anchoring a Cu(II)-Schiff base complex onto mesoporous MCM-41 with a surface-grafted -chloro group. Various analytical methods, including FT-IR, Low angle P-XRD, TGA, N-2 adsorption-desorption, SEM, TEM, and MPAES, were used to characterize the obtained catalyst. The composition and chemical state of Cu metal in the catalyst were identified using X-ray photoelectron spectroscopy. The catalyst MCM-41@CP@PAL@Cu was employed for the conversion of various alkenes to their epoxides with a yield of 99% in the model reaction. The catalyst can be reused for at least six times.

Summary: This study investigated the modulable valence states of Cu(0)/Cu(I)/Cu(II) active sites derived from MOF Cu(btc) under different calcination conditions to enhance CO2RR performance. Cu/C-T-air was more inclined to produce C2H4 due to the coexistence of Cu(I)/Cu(II) and abundant oxygen vacancy. Cu/C-450-air showed excellent CO2RR properties with 34.8% Faradaic efficiency of C2H4 at 1.1 V vs. RHE after a continuous measurement of 12 h. Cu/C-T-H2 was inclined to produce C2H4, while Cu/C-T-N2 tended to produce CH4, possibly due to smaller grain size and thinner carbon layer for more active sites and rapid electron transport.

Summary: The Lewis-acidic nature and robustness of NHC-Au(I) complexes make them highly effective catalysts for various reactions involving polyunsaturated substrates. Recently, the use of external oxidants or catalysts with pendant coordinating groups has allowed for exploration of Au(I)/Au(III) catalysis. In this study, N-heterocyclic carbene (NHC)-based Au(I) complexes with and without pendant coordinating groups were synthesized and characterized, and their reactivity in the presence of different oxidants was investigated. The results showed that the NHC ligand was oxidized to form NHC=O azolone products when iodosylbenzene-type oxidants were used, and quantitative recovery of gold in the form of Au(0) nuggets was achieved. The synthesized Au(0) nuggets were characterized to have purities above 90% using SEM and EDX-SEM. This study challenges the perceived robustness of the NHC-Au bond and presents a novel methodology for producing Au(0) nuggets.

Summary: By doping lead into Cu2O catalyst, the local electronic structure of Cu can be modified to improve the efficiency of CO2RR reaction, converting CO2 to C-2 hydrocarbons and oxygenate. The experimental results showed that the lead-doped catalyst achieved a C-2 faradaic efficiency of 83.9% and a current density of 203.8 mA cm(-2) at -1.1 V vs. RHE in a flow cell. X-ray absorption spectroscopy and Raman spectroscopy revealed that lead doping stabilized the Cu-0-Cu+ structure, enhanced CO adsorption and C-C coupling, leading to high activity for C-2 product formation. Theoretical calculations also indicated that lead doping lowered the energy barrier for both CO2 activation and C-C coupling processes.

Summary: Efficient deuterium separation from isotopic mixtures is achieved using the quantum sieving effect in porous materials with suitable pore size and open metal sites (OMSs). Synthetic HKUST-1-derived microporous mixed-valence Cu(I)Cu(II)-BTC exhibits enhanced D2/H2 isotope separation with high selectivity (SD2/H2) of 37.9 at 30 K, surpassing other porous materials. The introduction of Cu(I) macrocycles decreases the pore size and enhances the interaction of H2/D2 molecules on Cu(II) sites, contributing to the improved selectivity at low temperatures. The study provides insights into quantum sieving mechanisms and a new strategy for designing efficient isotope systems.

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.
