CO2 is selectively hydrogenated to HCO2H or hydrocarbons (HCs) by RuFe nanoparticles (NPs) in ionic liquids (ILs) under mild reaction conditions. The generation of occurs ILs containing basic anions, whereas heavy HCs (up C21 at 150 °C) are formed the presence nonbasic anions. Remarkably, high values TONs (400) and a TOF value 23.52 h–1 for formic acid with molar ratio 2.03 per BMI·OAc IL were obtained. Moreover, these NPs exhibited outstanding abilities formation long-chain efficient...
A holistic approach to fully characterize the physical–chemical properties of N doped TiO<sub>2</sub> and evaluate its true impact on photoelectrochemical applications.
Abstract Carbon nanodots (C‐dots) with an average size of 1.5 and 3.0 nm were produced by laser ablation in different imidazolium ionic liquids (ILs), namely, 1‐ n ‐butyl‐3‐methylimidazolium tetrafluoroborate (BMI.BF 4 ), bis(trifluoromethanesulfonyl)imide (BMI.NTf 2 ) ‐octyl‐3‐methylimidazolium (OMI.NTf ). The mean the nanoparticles is influenced alkyl side chain but not nature anion. However, varying anion (BF vs. NTf it was possible to detect a significant modification fluorescence...
3D printing has been employed to manufacture advanced reactor geometries based on miniaturised continuous-flow oscillatory baffled reactors (mCOBRs) and they have applied for the fouling free synthesis of silver nanoparticles with optimal size control.
Gold nanoparticles (AuNPs) display distinct characteristics as hydrogenation catalysts, with higher selectivity and lower catalytic activity than group 8–10 metals. The ability of AuNPs to chemisorb/activate simple molecules is limited by the low coordination number surface sites. Understanding pathways involved in reactions promoted supported crucial for broadening their potential applications. In this study, we demonstrate that mechanism catalyzed "clean" surfaces may proceed via homolytic...
Synergistic magic: copper single atom and nanocrystalline carbon nitride for selective CO 2 to methanol conversion.
The confinement of cerium oxide (CeO2) nanoparticles within hollow carbon nanostructures has been achieved and harnessed to control the oxidation cyclohexene. Graphitized nanofibers (GNF) have used as nanoscale tubular host filled by sublimation Ce(tmhd)4 complex (where tmhd = tetrakis(2,2,6,6-tetramethyl-3,5-heptanedionato)) into internal cavity, followed a subsequent thermal decomposition yield hybrid nanostructure CeO2@GNF, where are preferentially immobilized at graphitic step-edges GNF....
Boron nitride nanotubes (BNNTs) are an emerging class of molecular container offering new functionalities and possibilities for studying molecules at the nanoscale. Herein, BNNTs demonstrated as highly effective nanocontainers polyoxometalate (POM) molecules. The encapsulation POMs within occurs spontaneously room temperature from aqueous solution, leading to self-assembly a POM@BNNT host–guest system. Analysis interactions between host-nanotube guest-molecule indicate that Lewis acid–base...
Atomic-scale changes can significantly impact heterogeneous catalysis, yet their atomic mechanisms are challenging to establish using conventional analysis methods.
The incorporation of Ag nanoparticles onto BiVO4 (a known H2O oxidising photocatalyst) through magnetron sputtering to form a composite was studied. ICP-OES results showed that the loading on below 1% in all cases. UV-Vis DRS and CO2-TPD analyses demonstrated upon BiVO4, an increase extent visible light absorption CO2 adsorption seen. TEM imaging presence particles surface larger particles, while XRD analysis provided evidence for some doping into lattices. effect formation activity...
The efforts to increase the active surface area of catalysts led reduction metal particle size, down single atoms.
Developing sustainable, efficient catalysts for the electrocatalytic reduction of CO2 to valuable products remains a crucial challenge. Our research demonstrates that combining tin with nanostructured carbon support leads dynamic interface promoting transformation microparticles nanoparticles directly during reaction, significantly increasing formate production up 5.0 mol h–1 g–1, while maintaining nearly 100% selectivity. Correlative electrochemistry–electron microscopy analysis revealed...
During transmission electron microscopy imaging, nanoparticles display cyclic behaviour resembling that of living organisms: birth, growth, and decay, followed by the next generation repeating cycle.
Crystallographically preferred oriented porous Ta3N5 nanotubes (NTs) were synthesized by thermal nitridation of vertically oriented, thick-walled Ta2O5 NTs, strongly adhered to the substrate. The adherence on substrate and wall thickness NTs fine-tuned anodization, thereby helping preserve their tubular morphology for at higher temperatures. Samples studied scanning electron microscopy, high-resolution X-ray diffraction, Rietveld refinements, ultraviolet–visible spectrophotometry,...

We report the design and preparation of multifunctional hybrid nanomaterials through stabilization gold nanoparticles with thiol-functionalised organic-inorganic polyoxometalates (POMs). The covalent attachment POM forms new nanocomposites that are stable at temperatures pH values which destroy analogous electrostatically functionalised nanocomposites. Photoelectrochemical analysis revealed unique photochemical redox properties these systems.
The combination of a fuel cell and photocatalysis in the same device, called photo cell, is next generation energy converters. These systems aim to convert organic pollutants oxidants into using solar as driving force. However, they are mostly designed conventional stationary batch systems, generating low power besides being barely applicable. In this context, membraneless microfluidics allows use flow, porous electrodes, mixed media, improving reactant utilization output accordingly. Here,...
