Abstract

The invention belongs to the field of synthesis of gas-sensitive materials, and specifically discloses a parallel automatic synthesis device of gas-sensitive materials based on a solvothermal method. The device includes a feeding unit and a preparation unit, wherein: the inlet of the syringe pump in the feeding unit is connected to the corresponding raw material chamber, and its outlet is connected to the first switching valve, which is used to quantitatively extract and mix the gas-sensitive raw material from the raw material chamber; The outlet of the first switching valve is connected to the reaction module, and then the mixed gas-sensitive raw material is sent into the reaction module; the reaction kettle in the preparation unit is used to provide a reaction place for the gas-sensitive raw material to obtain a reaction product, and at the same time, the reaction kettle The outlet is connected with the first peristaltic pump and the first autosampler in turn, and then the reaction product is automatically transferred to the sample rack assembly; the second peristaltic pump is connected with the autosampler for extracting waste liquid from the sample rack assembly to This produces a gas-sensitive material. The invention can avoid the problem of excessive error caused by manual operation, and can effectively improve the synthesis efficiency of the gas-sensitive material at the same time.

Description

technical field [0001] The invention belongs to the field of synthesis of gas-sensitive materials, and more specifically relates to a parallel automatic synthesis device of gas-sensitive materials based on a solvothermal method. Background technique [0002] In the prior art, ball milling, electrospinning and solvothermal methods are generally used for the synthesis of gas-sensitive materials. Among them, the ball milling method refers to the method of using the rotation or vibration of the ball mill to grind and stir the raw materials into nano-sized particles. The disadvantage is that the synthesis is easy to introduce impurities and the controllability of the material synthesis is poor; The method of preparing polymer solution into nanometer-scale filamentous materials by spraying and stretching under the influence of the action is that it can only synthesize ribbon-shaped nanomaterials larger than 10nm, and can only simply control the synthesis process; solvothermal meth...
