Abstract Ammonia is synthesized directly from water and N 2 at room temperature atmospheric pressure in a flow electrochemical cell operating gas phase (half‐cell for the NH 3 synthesis). Iron supported on carbon nanotubes (CNTs) was used as electrocatalyst this half‐cell. A rate of ammonia formation 2.2×10 −3 g m −2 h −1 obtained , with stable behavior least 60 reaction, under an applied potential −2.0 V. This value higher than using noble metals (Ru/C) comparable reaction conditions....
Fe2O3-CNT samples are studied for the room-temperature electrocatalytic synthesis of NH3 from H2O and N2 in a gas–liquid–solid three-phase reactor. A 30 wt % iron-oxide loading was found to be optimal. The performances greatly depend on cell design, where possibility ammonia crossover through membrane has inhibited. reaction conditions also play significant role. effect electrolyte (type, pH, concentration) investigated terms current density, rate formation, Faradaic efficiency continuous...

Detonation nanodiamond possesses facile surface functional groups and can be chemically processed for many engineering applications. In this work, we demonstrate the functionalization of nanoscale diamond particles with aryl organics using Suzuki coupling reactions. route one, hydrogenated is derivatized diazonium to form bromophenyl−nanodiamond complex, subsequently reacted phenyl boronic acid generate biphenyl adduct. two, first acid−nanodiamond followed by cross arenediazonium...
Ni–Fe/AlO<sub>x</sub> with nanosheet structure, enhance the reducibility and stability of Ni-hydroxide during catalytic reaction due to formation spinel phase which stabilize smaller Ni nanoparticle a weaker interaction support.
We find that a one-dimensional groove array can be equivalent to negative water depth and excite unidirectional surface polaritons for waves. explain this phenomenon through theoretical analysis, numerical simulations, experiments. This shows the propagation direction of waves manipulated such simple structures, which will very important in offshore transportation environmental protection.
Polyvinylidene fluoride (PVDF), as the commercial cathode binder for lithium‐ion batteries, presents several practical challenges, including insufficient conductivity, weak adhesion to active materials, and use of toxic N‐methylpyrrolidone slurry preparation. However, while most water‐soluble binders can address aforementioned issues, they fail meet requirements high‐voltage cathodes. In this work, we innovatively employed a thermal pulse sintering strategy modify carboxymethyl cellulose...

Metal carbides M2 C (MXenes) with two-dimensional (2D) structure have been indicated as promising materials for N2 fixation, the activity being related to edge planes. Here, it is instead demonstrated that transformation from a 2D- (nanosheets) 3D-type nanostructure (nanoribbons) leads significant enhancement of fixation due formation exposed Ti-OH sites. A linear relationship observed between ammonia rate and amount oxygen on surface Ti3 C2 MXene.
Abstract Iron‐promoted nickel on γ‐Al 2 O 3 nanosheets shows enhanced catalytic activity, selectivity, and stability for carbon dioxide methanation, a relevant process energy storage transportation (power‐to‐gas) the future low‐carbon economy. Nanosheet‐type catalysts were synthesized by two‐step hydrothermal method characterized several physicochemical methods.

In this study, waste poly(ethylene terephthalate) (PET) fibers were chemically recycled into azo disperse dyestuffs. First, PET glycolytically degraded by excess ethylene glycol utilizing zinc acetate dehydrate as a catalyst. The glycolysis product, bis(2-hydroxyethyl) terephthalate (BHET), was purified through recrystallization and hydrolyzed terephthalic acid (TPA). Thereafter, BHET TPA nitrated, reduced azotized to obtain diazonium salts. Finally, the obtained salts coupled with...
Abstract Green NH 3 production by direct electrocatalytic synthesis from N 2 and H O is still a challenging reaction, which requires us to better understand the nature of active materials. We show here that iron oxide (Fe ) nanoparticles (supported over carbon nanotubes, CNTs) become more than corresponding samples after reduction form Fe‐ or Fe N‐supported nanoparticles, both indicated as species in thermal catalytic ammonia. Characterization data, however, indicate even for these N−CNT...
