Preparation And Property Of 3,4,9,10-Perylenetetracarboxylic Dianhydride-amino Acid Interlayer Two-dimensional Nanometer

Two-dimensional nanocomposites have unique electrical properties and lager specific surface area.Layer of atoms and atoms are connected by covalent bonds,and between the layers of atoms interact with atoms by vander Waals force,because it is different between reaction inside the layer and interlayer.The atoms in and between the layers are connected by covalent bond and Vander Waals force,respectively,which result in obvious difference in properties and many unique properties have applications in catalytic chemical sensing and energy storage.Preparation methods of the two-dimensional nanocomposites are mainly divided into top-down detachent and bottom-up synthesis,and ultrasonic liquid stripping method is taking advantage of greener,lower cost and simple operation.In this thesis,two-dimensional nanocomposites were synthesized by ultrasonic liquid stripping.Perylene-animoacid compounds that have a big?force organic molecular were regardedas intercalating agentsand inserted into the matrix materials such as graphene oxide?Go?,MoS₂,and g-C₃N₄,finally forming two dimensional nanocomposite materials,the related properties of the composite materials are as follows.?1?Two-dimensional nanocompositesbased on GO were prepared by taking small organic molecules tetracarboxylic acid dianhydride-alanine?NAPD?,-phenylalanine?NPPD?,and-tyrosine?NTPD?as the intercalatorusing ultrasonic liquid stripping method.The synthesized compounds were characterized by AFM,FT-IR,XRD,and SEM,the result of AFM showed the mean thickness of the materials is only 1.588nm.?2?Two-dimensional nanocompositesbased on MoS₂ were prepared by taking small organic moleculestetracarboxylicaciddianhydride-alanine?NAPD?,-phenylalanine?NPPD?,dianhydride-aspartate?NAAPD?and-tyrosine?NTPD?as the intercalatorusing ultrasonic liquid stripping method.The synthesized compounds were characterized by AFM,FT-IR,XRD,and SEM,the result of AFM showed the mean thickness of the materials is only 1.819nm.?3?Two-dimensional nanocompositesbased on g-C₃N₄ were prepared by taking small organic moleculestetracarboxylicaciddianhydride-alanine?NAPD?,-phenylalanine?NPPD?,dianhydride-aspartate?NAAPD?and-tyrosine?NTPD?as the intercalatorusing ultrasonic liquid stripping method.The synthesized compounds were characterized by AFM,FT-IR,XRD,and SEM,the result of AFM showed the mean thickness of the materials is only 2.512nm.(Further research demonstrates the NAPD inserted g-C₃N₄?g-C₃N₄/NAPD?nanocomposite showed obvious performance in the catalysis of hydrogen evolution reaction?HER?.
