Abstract

The invention discloses a sensing material for quickly detecting biological hydrogen sulfide and a preparation method of the sensing material, and belongs to the technical field of biological H2S detection. The sensing material is a heterostructure array material which Cu2O and Fe2O3 are periodically and alternately distributed on. The preparation method comprises the following steps: preparing anelectro-deposition solution; taking an ultra-pure copper foil and copper wire as electro-deposition electrodes, then putting the electrodes on an insulation substrate inside an electrochemical growthchamber in parallel, dropwise adding electrolyte between the two electrodes, and covering with cover glass; controlling a temperature to freeze the electrolyte, keeping at a constant-temperature state and standing for 20 to 50 minutes; exerting half sine deposition potential on the electrodes to deposit the electrolyte; and after deposition, taking the substrate out and cleaning with ultrapure water to obtain the sensing material for quickly detecting the biological hydrogen sulfide. The sensing material disclosed by the invention can be used for quickly detecting the biological hydrogen sulfide.

Description

technical field [0001] The invention relates to a sensing material used for quick detection of biological hydrogen sulfide and a preparation method thereof, which belong to biological hydrogen sulfide 2 S detection technology field. Background technique [0002] Currently, using the detection of biological H 2 The disease diagnosis technology of S markers has not been practically applied, especially the rapid and convenient detection technology scheme needs further research. Bio-H 2 The reason why the rapid and convenient disease diagnosis technology of S detection has not been realized is mainly caused by the deficiency of existing testing methods, which are used to detect biological H 2 The methods of S mainly include: colorimetric method, high performance liquid chromatography, gas chromatography, metal-induced sulfur deposition method and fluorescent probe method, etc. The fluorescent probe method is mainly to combine the fluorescent probe with the required recogniti...
