Description

technical field [0001] The invention belongs to the field of material chemistry, and in particular relates to a compound with electrochemical response to formaldehyde and a preparation method thereof. Background technique [0002] Electrocatalysis means that under the action of an electric field, the modifiers (electrically active and non-electroactive) present on the electrode surface or in the solution phase can promote or inhibit the electron transfer reaction that occurs on the electrode, while the electrode surface or in the solution phase The chemical action of the modifier itself does not change. The reaction mechanism is to affect the energy of intermediate state particles through surface adsorption, and then affect the activation energy of the reaction. Electrocatalysis is divided into oxidation-reduction electrocatalysis and non-oxidation-reduction electrocatalysis. [0003] At present, electrocatalysis is mainly used in electrocatalytic treatment of organic sewa...

Problems solved by technology

For example, using Raman spectroscopy to detect formaldehyde (Zhang Qianxuan, Guan Xuchun, Cui Houxin, a device and method for formaldehyde detection, application publication number CN102749318), this method is too complicated to operate and analyze

There is also a method for detecting formaldehyde using thermal sensing properties (Liu Dongfang, Jiang Feng, Ma Xiaocong, formaldehyde gas sensor, application publication number CN101825604A). When this method is used, the heating electrode group must heat the gas sensing layer to a very high temperature (300 °C) can be detected normally, consumes a lot of energy, and has poor safety
