Investigation On Preparation And Application Of Manganese Phosphate Nanoflowers–based Hybrid Materials

As a kind of new material, inorganic/organic has been widely research and application in sensors and biotechnology.In this paper, respectively, four kinds of manganese phosphate prepared by self-assembly method based nano hybrid material, on the basis of the research on its various performance fully, sensitive to it as a catalyst materials and sensor makes a detailed study of the application of membrane material. First of all, using self-assembly method out Mn3(PO4)2@BSA nano hybrid material.At the same time, adopt the method of chemical deposition in nano hybrid material surface deposition Pt nanoparticles to form methanol catalyzed with catalyst.Respectively by Fourier infrared spectrometer, XRD, XPS, SEM and TEM analysis testing technology such as chemical structure and surface morphology of the material.The study found that by using self-assembly Mn3(PO4)2@BSA nano spend about 20 nm in diameter of hybrid material petals particles;And load after Pt nanoparticles morphology of nanometer flower hybrid materials without change.Electrochemical workstation on the electrochemical catalytic properties test found that nano flower has the very high catalytic ability of methanol and high resistance to poisoning.In manganese phosphate take load of hybrid material Pt nanoparticles catalyst of methanol application, this paper also studied the materials in the application of electrochemical biosensors. Prepared by self-assembly method from Mn3(PO4)2@BSA@Au, Mn3(PO4)2@Ig G and Mn3(PO4)2@RACanti three nano hybrid material.FTIR, XRD, and SEM were used respectively to test technology such as analysis of chemical structure and surface morphology of the material.Electrochemical analysis and technical analysis by preparation Mn3(PO4)2@BSA@Au 、 Mn3(PO4)2@Ig G �'�Mn3(PO4)2@RACanti three flower hybrid nanomaterials testing the limits of detection concentration(LDC) of lake dopamine, respectively, 4.6, 9.32, 26 pg. m L-1.Results show that the self-assembly technology of preparation of manganese phosphate nanometer flower hybrid material not only has high biocompatibility, but also has good electrochemical catalytic performance, for the manganese phosphate nanometer spend other application research of hybrid material may provide the experimental basis.
