Complexometric Titration: Ligands00:43

Complexometric Titration: Ligands

Different monodentate and polydentate ligands are used as complexing agents in complexometric titration reactions. The formation of complexes by mono- and bidentate ligands involves two or more intermediate steps, limiting their use as complexing agents. In comparison, polydentate ligands can form complexes with metal ions in a single-step process, facilitating sharper end points. This means polydentate ligands, such as amino carboxylic acid derivatives, are most commonly employed in...

Area of Science:

  • Materials Science
  • Nanotechnology
  • Catalysis

Background:

  • High-entropy alloys (HEAs) offer tunable compositions and catalytic potential.
  • Synthesizing HEAs into ultrathin, low-dimensional nanostructures is challenging due to thermodynamic instability.

Purpose of the Study:

  • To develop a general, low-temperature method for creating single-phase, subnanometer high-entropy alloy ribbons (SNRs).
  • To achieve the world's thinnest HEA nanostructured materials for advanced applications.

Main Methods:

  • Galvanic exchange reaction between metal precursors and a silver nanowire template for metal atom nucleation.
  • Co-reduction of metal precursors on the nanowire template.
  • Removal of the inner silver core to yield suprathin HEA SNRs.
  • Density functional theory (DFT) calculations to understand crystallization and stabilization mechanisms.

Main Results:

  • Successful incorporation of up to eight metallic elements into single-phase subnanometer HEA ribbons.
  • Demonstrated flexible control over HEA SNR composition and concentration.
  • HEA SNRs showed significantly enhanced electrocatalytic activity for oxygen reduction reactions in fuel cells.
  • Exhibited high discharge capacity, low charge overpotential, and excellent durability in Li-O2 batteries.

Conclusions:

  • The novel low-temperature method enables the fabrication of unprecedentedly thin HEA nanostructures.
  • Crystallization and stabilization are influenced by the silver template and correlate with Pt/Pd concentrations.
  • The developed HEA SNRs demonstrate superior electrochemical performance, attributed to synergistic effects of constituent elements.
