Silica and alumina coating can improve the chemical and thermal stability of nanoparticles. This fact has great importance in the in-situ study of catalytic reactions. The high sensitivity of the SHINERS surfaces makes these nanostructures a promising tool for the study of liquid-solid interfaces, especially in spectroelectrochemistry. [3] [12 ...
Spectroscopic and electrochemical techniques that form the spectroelectrochemistry. Spectroelectrochemistry (SEC) is a set of multi-response analytical techniques in which complementary chemical information (electrochemical and spectroscopic) is obtained in a single experiment.
Potentiometry passively measures the potential of a solution between two electrodes, affecting the solution very little in the process. One electrode is called the reference electrode and has a constant potential, while the other one is an indicator electrode whose potential changes with the sample's composition.
In electrochemistry, cyclic voltammetry (CV) is a type of voltammetric measurement where the potential of the working electrode is ramped linearly versus time. Unlike in linear sweep voltammetry , after the set potential is reached in a CV experiment, the working electrode 's potential is ramped in the opposite direction to return to the ...
A well-known electrosynthesis is the Kolbe electrolysis, in which two carboxylic acids decarboxylate, and the remaining structures bond together:; A variation is called the non-Kolbe reaction when a heteroatom (nitrogen or oxygen) is present at the α-position.
The Handbook of Electrochemistry, edited by Cynthia Zoski, is a sourcebook containing a wide range of electrochemical information.It provides details of experimental considerations, typical calculations, and illustrates many of the possibilities open to electrochemical experimentators.
Enzyme kinetics: Why do some enzymes exhibit faster-than-diffusion kinetics? [13]Protein folding problem: Is it possible to predict the secondary, tertiary and quaternary structure of a polypeptide sequence based solely on the sequence and environmental information?
+0.12 v The activation overpotential is the potential difference above the equilibrium value required to produce a current that depends on the activation energy of the redox event. While ambiguous, "activation overpotential" often refers exclusively to the activation energy necessary to transfer an electron from an electrode to an anolyte .
