Interfacial Electrochemical Methods: Overview01:06

Interfacial Electrochemical Methods: Overview

207
Interfacial electrochemical methods focus on the phenomena occurring at the boundary between an electrode and a solution, as opposed to bulk methods that concentrate on the solution's overall properties. These interfacial methods are classified as either static or dynamic based on the presence of a nonzero current in the electrochemical cell and the consistency of analyte concentrations. Static methods, such as potentiometry, measure the cell's potential without any significant current...

Ladder Diagrams: Redox Equilibria

409
Ladder diagrams are useful tools for understanding redox equilibrium reactions, especially the effects of concentration changes on the electrochemical potential of the reaction. The vertical axis in the redox ladder diagrams represents the electrochemical potential, E. The area of predominance is demarcated using the Nernst equation.
Consider the Fe3+/Fe2+ half-reaction, which has a standard-state potential of +0.771 V. At potentials more positive than +0.771 V, Fe3+ predominates, whereas Fe2+...

Electrochemistry: Overview01:04

Electrochemistry: Overview

633
Electrochemistry is the branch of chemistry that studies the relationship between electrical quantities and chemical reactions, particularly oxidation and reduction. Oxidation is the loss of electrons from a substance, whereas reduction refers to the gain of electrons. A substance with a strong electron affinity is called an oxidizing agent (oxidant), and a reducing agent (reductant) is a species that donates electrons. Oxidation and reduction processes are pivotal to electrochemical reactions,...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

Electrolysis

25.8K
In a galvanic cell, the electrical work is done by a redox system on its surroundings as electrons produced by the spontaneous redox reactions are transferred through an external circuit. Alternatively, an external circuit does work on a redox system by imposing a voltage sufficient to drive an otherwise nonspontaneous reaction in a process known as electrolysis. For instance, recharging a battery involves the use of an external power source to drive the spontaneous (discharge) cell reaction in...

Controlled-Potential Coulometry: Electrolytic Methods

113
Controlled-potential coulometry, also known as potentiostatic coulometry, employs a three-electrode system in which the working electrode's potential is precisely regulated using a potentiostat. Platinum working electrodes are utilized for positive potentials, while mercury pool electrodes are favored for extremely negative potentials. The platinum counter electrode is separated from the analyte using a membrane or salt bridge to avoid interference in the analysis.
The chosen potential...

  • Electrochemistry
  • Catalysis

Background:

  • Interfacial engineering is key for efficient electrochemical carbon dioxide reduction (CO2RR).
  • Weak interactions and instability at interfaces limit CO2RR performance.

Purpose of the Study:

  • To investigate the pure interface effect on CO2RR by embedding silver nanoclusters (Ag NCs) onto porous ceria nanospheres (CeO2 NSs).
  • To enhance the performance of CO2RR catalysts by optimizing the Ag-CeO2 interface.
  • To understand the mechanism behind interface-induced performance improvements.

Main Methods:

  • Synthesis of Ag nanoclusters embedded onto CeO2 nanospheres (Ag NCs@CeO2 NSs).
  • Electrochemical characterization of CO2RR performance (current density, Faraday efficiency, overpotential).
  • Computational studies (free energy and differential charge calculations) and X-ray photoelectron spectroscopy (XPS) for mechanistic analysis.

Main Results:

  • Ag NCs@CeO2 NSs exhibited significantly enhanced current density, Faraday efficiency (FE), and energy efficiency compared to individual components and dispersed Ag NCs.
  • Achieved a high CO FE of over 70.0% at an ultralow overpotential (η) of 146 mV.
  • Demonstrated superior performance attributed to the Ag-CeO2 interface.

Conclusions:

  • The Ag-CeO2 pure interface effectively promotes CO2RR to CO at lower overpotentials.
