Electrocatalyst Fabrication Using Metal Nanoparticles Prepared in Ionic Liquids

Abstract

Metal nanoparticle‐based electrocatalysts are widely used in electronic devices, which serve for electrochemical reactions like oxygen reduction reaction, alcohol oxidation and CO2 reduction reaction. These catalyst‐dependent reactions are the key of the emerging clean energy systems. Catalyst design and synthesis therefore have received keen attention in past decades. We are motivated to study synthesis approaches of metal nanoparticle‐based electrocatalysts using ionic liquids (ILs), which are promising solvents for the nanoparticle preparation because of their unique physicochemical properties. In this personal account, we review our previous and present works on nanoparticle preparation in IL and utilization of the obtained nanoparticles as electrocatalysts.

Development of Wet Vacuum Technologies with Ionic Liquids Inspired by a Pipe Dream Discussion

“…16. [51][52][53][54][55][56] Our detailed experiments revealed that the IL layer, which remains after cleaning, acts as a binder between the Pt nanoparticles and the carbon support and impedes their direct contact that enhances carbon support corrosion. 54 When the carbon materials having inert surfaces are used as carbon substrates for cathode electrodes in fuel cells, it is anticipated to decelerate oxidative deterioration of the carbon substrates that occurs when a more positive potential is applied to the electrode than the potential in normal operation.…”

How To Get Isocyanate?

“…Ionic liquids (ILs), recognized as environmentally friendly solvents and functional materials, have attracted substantial attention in various scientific domains, including chemistry, biology, physics, and engineering. ILs serve diverse functions, such as catalysts, solvents, and catalyst carriers, and many catalytic reactions can be efficiently carried out in ionic liquid systems. − Because of their high thermal stability, lack of volatility, reusability, and low vapor pressure, ILs offer substantial advantages for the liquid-phase catalytic synthesis of isocyanates. Han et al conducted a thermal analysis to explore the changes in mass within the ionic liquid and organic solvent during the heating process while investigating the thermal decomposition of methyl 1,6-adipic carbamic acid (MHDC) in various ionic liquid media using Bi 2 O 3 /Fe 2 O 3 as a catalyst, as illustrated in Figure .…”
