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

Embodiment 1

[0021] Sulfadiazine (0.25 mmol, 0.063 g), Co(OAc) 4H was added to a 25 mL Teflon liner 2 O (1.0mmol, 0.249g), 4,4'-bipyridine (0.25mmol, 0.039g) and KOH (0.25mmol, 0.014g), and an appropriate amount of water 5mL were added, and stirred to mix evenly. Seal the Teflon liner and place it in a stainless steel reaction kettle. Then put the reaction kettle into an oven, heat at 60°C for 72h; then cool down to room temperature naturally, and open the reaction kettle to obtain brown-yellow crystals.

Embodiment 2

[0023] Sulfadiazine (0.5 mmol, 0.125 g), CoSO 4 ·7H 2 O (0.5mmol, 0.140g), 4,4'-bipyridine (0.25mmol, 0.039g), KOH (0.25mmol, 0.014g), add an appropriate amount of water 10mL, stir to mix evenly. Seal the Teflon liner and place it in a stainless steel reaction kettle. Then put the reaction kettle into an oven, heat at 80°C for 48h; then cool down to room temperature naturally, and open the reaction kettle to obtain brown-yellow crystals.

Embodiment 3

[0025] Sulfadiazine (0.5 mmol, 0.125 g), CoCl 2 ·6H 2 O (0.5mmol, 0.139g), 4,4'-bipyridine (0.5mmol, 0.078g), KOH (0.5mmol, 0.028g), add an appropriate amount of water 10mL, stir to mix evenly. Seal the Teflon liner and place it in a stainless steel reaction kettle. Put the reaction kettle into an oven, heat at 100°C for 24h; then cool it down to room temperature naturally, and open the reaction kettle to obtain brown-yellow crystals.

Abstract

The invention discloses a compound with electrochemical response to formaldehyde and a preparation method thereof. The cobalt complex electrocatalytic material is a 4,4'-dipyridine sulfadiazine cobalt compound with certain space structure, and the molecular formula is C40H34CoN12O4S2. The preparation method of the sulfadiazine cobalt compound electrocatalytic material is implemented by carrying out chemical reaction on sulfadiazine with conjugated extended pai bond and 4,4'-dipyridine to obtain the novel cobalt compound. The compound used as an electrocatalytic active material has accurate space structure and accurate molecular formula; the cobalt ions can form stable coordinate bonds with the ligand by utilizing 3d orbit, thereby being beneficial to the transfer of electrons and promoting the proceeding of the electrochemical reaction, and thus, the compound has favorable electrocatalytic activity for formaldehyde. The cobalt complex used as the electrocatalytic active material has wide application prospects.

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...
