Abstract
The present application relates to a kind of preparation methods of COFs iodine vapor electrochemical sensor based on redox activity, which comprises adding COFs with redox activity into methanol, obtaining a mixture, transferring the mixture into the active area of interdigital electrode, evaporating solvent by heating, and obtaining iodine vapor electrochemical sensor.The iodine vapor electrochemical sensor of the present application has high stability, high selectivity and high sensitivity.When air mixed with iodine vapor passes through the electrochemical sensor, iodine is captured by the polymer film.Based on redox reaction, the impedance of the electrochemical sensor decreases rapidly, and iodine vapor can be detected sensitively and quickly.The preparation is simple, the cost is low, the process is simple and easy to produce, and the adsorption capacity is high, etc., and has good application prospect in the field of iodine vapor sensing technology, etc.
