Limiting Reactant

58.3K
The relative amounts of reactants and products represented in a balanced chemical equation are often referred to as stoichiometric amounts. However, in reality, the reactants are not always present in the stoichiometric amounts indicated by the balanced equation.

Catalysis

26.5K
The presence of a catalyst affects the rate of a chemical reaction. A catalyst is a substance that can increase the reaction rate without being consumed during the process. A basic comprehension of a catalysts’ role during chemical reactions can be understood from the concept of reaction mechanisms and energy diagrams.

Electrolysis

25.9K
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

127
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...

Controlled-Current Coulometry: Overview

153
Controlled current coulometry, also known as amperostatic coulometry, is a technique used in electrochemical analysis to measure the quantity of a substance through the controlled passage of current. It involves the application of a constant current to an electrochemical cell containing the analyte of interest. As the current flows through the cell, the analyte undergoes a redox reaction at the electrode surface, resulting in a charge transfer. By monitoring the time required for a certain...

Area of Science:

  • Electrochemistry
  • Materials Science
  • Environmental Engineering

Background:

  • Direct electrolysis of CO2 absorption solutions (bicarbonate solutions) integrates carbon capture and utilization, avoiding CO2 recovery.
  • In-situ CO2 generation during bicarbonate electrolysis enhances CO2 utilization efficiency compared to conventional methods.
  • High precious metal catalyst loading (approx. 4.0 mg cm-2) is a major limitation for current bicarbonate electrolysis.

Purpose of the Study:

  • To develop a cost-effective and scalable electrode preparation method for bicarbonate electrolysis.
  • To reduce the loading of silver nanoparticles (AgNPs) while maintaining high catalytic performance.
  • To improve the efficiency of electrochemical CO2 conversion.

Main Methods:

  • Utilized flame spray pyrolysis (FSP) to deposit silver nanoparticles (AgNPs) onto carbon cloth.
  • Coated the FSP-deposited AgNPs with commercial AgNPs (Cml-AgNPs).
  • Evaluated the performance of the FSP + Cml-AgNPs cathode in bicarbonate electrolysis.

Main Results:

  • The FSP + Cml-AgNPs cathode achieved comparable CO selectivity with only one-third of the AgNPs loading compared to conventional airbrush deposition.
  • The FSP technique provided high surface area and uniform coverage of AgNPs.
  • Demonstrated a significant reduction in precious metal catalyst usage.

Conclusions:

  • The FSP-based electrode preparation method is a scalable and economical solution for bicarbonate electrolysis.
  • This approach enhances catalyst performance and particle dispersion for electrochemical CO2 conversion.
  • Offers a promising pathway for efficient and cost-effective carbon capture and utilization technologies.
