Objective: To determine the concentration of vanillic acid by polyoxometal-based host-guest frame material modified glass carbon electrode. Methods: A stable polyacid-based host-guest metal-organic framework material PMoV@MIL-100(Fe) was synthesized by combining vanadium-substituted phosphomolybdic acid (PMoV) with MIL-100(Fe) according to the synthesis method of polyacid-based host-guest framework materials. Functional composite material PMoV@MIL-100(Fe)@Pt was prepared by composite metal nanoparticles with PMoV@MIL-100(Fe) by solution method, and was used to modify glassy carbon electrode, detect vanillic acid, and prepare vanillic acid electrochemical sensor. Results: Under optimal conditions, the vanillic acid electrochemical sensor showed wide linear range and high sensitivity. Rapid and sensitive detection of vanillic acid could be performed under mild conditions with excellent stability. Conclusion: The electrochemical sensor constructed in this experiment provides a new idea for the detection of vanillic acid.
