Formation of Complex Ions03:45

Formation of Complex Ions

23.7K
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Nitrous acid is a relatively weak and unstable acid prepared in situ by the reaction of sodium nitrite and cold, dilute hydrochloric acid. In an acidic solution, the nitrous acid undergoes protonation when it loses water to form a nitrosonium ion—an electrophile. Nitrous acid reacts with primary amines to give diazonium salts. The reaction is called diazotization of primary amines.

Electrophilic Aromatic Substitution: Nitration of Benzene

6.0K
The nitration of benzene is an example of an electrophilic aromatic substitution reaction. It involves the formation of a very powerful electrophile, the nitronium ion, which is linear in shape. The reaction occurs through the interaction of two strong acids, sulfuric and nitric acid.

Area of Science:

  • Materials Science
  • Electrochemistry
  • Catalysis

Background:

  • Electrocatalytic reduction of nitrate (NO3 RR) is crucial for sustainable ammonia (NH3) synthesis and carbon neutrality.
  • Atomically precise nanoclusters offer insights into reaction mechanisms but often suffer from poor stability.

Purpose of the Study:

  • To develop a stable and highly efficient electrocatalyst for nitrate reduction to ammonia.
  • To investigate the synergistic effects of combining atomically precise nanoclusters with MXene for enhanced catalytic performance.

Main Methods:

  • Synthesis of (NH4)9[Ag9(mba)9] nanoclusters (Ag9 NCs) and their loading onto Ti3C2 MXene.
  • Electrocatalytic testing of the Ag9/MXene composite for nitrate reduction in a neutral medium.
  • Stability assessment through long-term chronoamperometric measurements.

Main Results:

  • The Ag9/MXene composite demonstrated highly efficient electrocatalytic nitrate reduction to ammonia.
  • A tandem catalysis process within the composite structure significantly improved NH3 selectivity and Faradaic efficiency.
  • The Ag9/MXene catalyst exhibited enhanced stability, with no decay in current density after 108 hours of reaction, outperforming individual Ag9 NCs.

Conclusions:

  • The Ag9/MXene composite presents a promising strategy for improving the activity and stability of atomically precise metal nanoclusters.
  • This work expands the mechanistic understanding and application potential of metal nanoclusters in electrocatalysis for ammonia synthesis.
