Description

Preparation method of cobalt-based one-dimensional nano material
Technical Field
The invention belongs to the technical field of synthesis of nano materials, and particularly relates to a preparation method of a cobalt-based coordination polymer one-dimensional nano material.
Background
Nitrilotriacetic acid, a common organic chelator, is often used to immobilize proteins for biochemical detection in analytical chemistry; the cobalt ion is taken as a hexacoordinate metal ion and can be coordinated and complexed with nitrilotriacetic acid to form a ternary complex. The reaction cannot take place at room temperature due to the less soluble nitrilotriacetic acid. As the temperature of the solution rises, the nitrilotriacetic acid is gradually dissolved in the solution and reacts with cobalt ions to generate a one-dimensional nano material structure, wherein the cobalt ions are fixed on the positions of carboxyl groups. A single polymer molecular chain can be self-assembled in a highly ordered way to form a one-dimensional nano material structure. The formed one-dimensional nano material sediment reduces the concentration of nitrilotriacetic acid in the solvent, so that more nitrilotriacetic acid is dissolved in water, and raw materials are continuously provided for growing the cobalt-based one-dimensional nano material.
The existing common reaction kettle is insulated for 6 hours at 180 ℃ in an oven to carry out solvothermal reaction to prepare the cobalt-based one-dimensional nano material, the synthetic method has high danger and harsh reaction conditions; moreover, different operators can lead to different sealing degrees of the reaction kettle, so that the pressure intensity in the lining is different and the repetition rate of the sample is not high during the solvent thermal reaction; the heat preservation time is long, the working efficiency is low, the energy consumption is high, the requirement on large-scale production is high, and the industrial production is difficult to realize; therefore, the traditional synthesis method is not very suitable from the viewpoint of environmental protection, and has a serious energy waste phenomenon. Therefore, the search for a method for effectively synthesizing the cobalt-based coordination polymerization one-dimensional nano material, which has the advantages of mild reaction conditions, high efficiency and low cost and meets the requirement of green chemistry, becomes the target pursued by researchers for a long time.
