| Antimony sulfide materials are highly anisotropic and belong to inorganic semiconductors.Its spectral range,light sensitivity and electrochemical performance are all excellent,so it has attracted much attention.Antimony sulfide materials with novel morphology and structure often possess unique properties and have new applications in many fields.However,the current applied research of antimony sulfide materials is mainly concentrated in fields such as saler cells,phatocetalysts,and merphalogy control of antimony sulfide nanematarials,and there are many research subjects whose main research direction is electrochemical sensing performance.Considering this factor,in this paper,we prepared various antimony sulfide nanomaterials with different microscopic morphologies by simple selvetharmel synthesis methods,and conducted a series of studies on the electrochemical properties of hydrazine hydrate.First,the sorbothermal reaction is used to prepare antimony sulfide,and the merpholagy of aetimony sulfide is adjusted by varying the salfur sourae,solvant,time,tamperutare,and addition of crystal growth regulators.Observe the micrescapic marphalegy and scale,crystel stracture and chemical cemposition of the material using SEM,EDS,XRD,infrared spactroscepy and Raman spectroscopy.The tast resvlts show that the praduct merpholagy is rod,cluster.,Branch,double potash flower,etc.It has a three-dimensional self-assembled structure,and it has been confirmed that the manufactured product is a pure antimony sulfide material.Hydrezlna hydrete plays an extramely impertant rale in the chamical indastry,is used as a rew metarial for foaming agents,detargants,antidiebetic agants,pasticldes,etc.,and has a wide range of uses as rocket propellants.It is highly corrosive and highly reducing,and is easily inhaled through the skin and mouth to endanger health.The elactrechemlcal seasing mathod allews rapid detection of the contant of hydrezine in the salutien.In this pepar,in order to detect the elactrechemlcal sensiog perfarmence of a preduct against hydrezina hydrete,a 3-electrode system elactrechemicel workstetion is used and a CV curve test selects 2b-Sb2S3matarials that perfarm well.,Then extracted the IT curve for hydrazine.Hydrate measurements showed that the 2b-Sb2S3modified electrodes had a low detection limit（0.1μM）and were relatively sensitive:0.5-8μM and 8-20μM of hydrazine hydrate.The two concentration ranges correspond to a sensitivity of 2b-ITO electrodes for detection of hydrazine hydrate 54.8μA/（μM·cm2）and 265.2μA/（μM·cm2）,and a rational description of their electrochemical sensing mechanism.In addition,by changing the p H values of the study electrodes（ITO electrodes,FTO electrodes）,buffers,adding interfering substances,and testing the repreducibllity and stebilty of the elactrode cetalyst meterial,the finol exparimental results all show thet we praparod The 2b-Sb2S3modified electrode has relatively high value and can be used in the electrochemical sensing of hydrazine. |
