Problems solved by technology

[0005] (1) Dependent data processing software such as Origin or MATLAB is expensive
[0006] (2) There are many versions of data processing software, which may cause incompatibility with the operating software and make it unusable
[0007] (3) Some operating software and data processing software do not have cross-platform functions, and can only be used for some operating systems, and some computers cannot be used
[0008] (4) The data still needs to be manually input or adjusted (such as the oxidation peak reduction peak current potential), which increases the workload and manual errors, and the accuracy of the calculation results depends on the professional technical level of the operator

Embodiment Construction

[0043] The present invention will be described in more detail below with examples in conjunction with the accompanying drawings.

[0044] (1) Raw data measurement stage, such as figure 1 shown. The working electrode of the three-electrode system reaction device is a metal electrode (such as a platinum disk electrode); the reference electrode is a metal wire (such as a platinum wire); the counter electrode is a metal sheet (such as a platinum sheet); Accelerate the dissolution of reactants. First clean the reaction device and related parts to ensure that they are clean and dry. Add the reactant to the reaction vessel, heat and stir to dissolve until stable. Connect the reaction device to the wire of the electrochemical workstation, start the electrochemical workstation, set the automatic measurement parameters, and wait for the measurement to be completed. After the measurement is complete, export the data and set the file name to the format of "Others-Celsius-Rate-Others.t...

Abstract

The invention provides a method for determining electrode reaction parameters. The method comprises the following steps: accessing three electrodes of a three-electrode system reaction device to an electrochemical workstation, measuring initial data by utilizing a cyclic voltammetry, processing the initial data to obtain electrochemical reaction parameters and data relationship graph; processing the initial data, namely, firstly reading files in batch, storing the read data by adopting a four-layer data structure, reading the information of temperature and scanning rate from a file name, correcting and preprocessing the data after all data is read and stored, drawing according to a result after the correction, judging the reaction type, and combining a computational formula to obtain the diffusion coefficient, reaction activating energy and rate constant data, and finally displaying the calculation result and graph. By adopting the method, the reaction kinetics and the thermodynamics parameters of the electrode can be conveniently measured, the determination period is greatly shortened, the overall workload is alleviated, the overall price is low, and the final calculation result and drawn graph can meet the majority of requirements.

Description

technical field [0001] The invention relates to a method for measuring electrode reaction parameters, in particular to a method for measuring electrode reaction parameters using cyclic voltammetry. Background technique [0002] Many electrode reactions are controlled by the diffusion of substances. Diffusion is caused by the gradient of an electrochemical potential. The diffusion current reflects the diffusion part of the flow of electroactive substances on the electrode surface. From a microscopic point of view - in the discontinuous source model, it is considered that the diffusion coefficient D 0 It is a constant related to the step size and step frequency. Combined with Fick's diffusion law, we can know the law of the concentration of reactants with time after obtaining the diffusion coefficient, which is used to guide us to choose the best reaction conditions. The reaction rate constant reflects the speed of the chemical reaction, and the calculated reaction rate const...
