In this study, graphene oxide was first synthesized using the modified Hummers method and then cross-linked with chitosan and a three-dimensional graphene aerogel was prepared. The structure and porosity of 3D graphene aerogels were investigated by FESEM analysis. XRD, FTIR, TGA, EDS and nitrogen adsorption and desorption temperatures (based on BET theory) were also used to eva‎luate the properties of the aerogel. This aerogel was then used along with hydrazine hydrate as a reducing agent to catalytically reduce beta-nitrosystyrene and its derivatives and convert them to phenylethylamines. In this regard, 0.3 w% of catalyst, 0.25 mmol of hydrazine hydrate, temperature of 50 ° C and neutral nitrogen atmosphere were determined as the most optimal reaction conditions. To eva‎luate the progress of the reaction, thin layer chromatography with hexane and ethyl acetate ratio (1: 1) and also to obtain the conversion percentage of visible-ultraviolet analysis were used. The maximum wavelength in this reaction was set at 304 nm. Finally, the most optimal product was purified and GC-MS analysis was performed to ensure the structure of the product. In the end, with this method, some different derivatives of beta-nitrosterine were reduced, which converted their conversion percentage to 100%
