NOVELTY - Method for inducing preparation of two-dimensional magadiite/graphene oxide nanosheet composites involves (1) dissolving 0.50-0.90 g structure directing agent in 5.00-8.00 g water at 60-80° C, obtaining solution (A), (2) dissolving 1.40-1.50 g sodium hydroxide and 3.00-3.90 g sulfate source in 33.00 g water, obtaining solution (B), (3) adding 2.08-3.50 g silicon source and 3.00-4.00 g solution (B) to solution (A) obtained in step (1), adding 1-10 mL of graphene oxide nanosheet dispersion with a concentration of 1-50 mg/mL, obtaining gel (C), (4) increasing temperature of the gel (C) to 60-80° C, aging for 5-8 hours under stirring conditions, obtaining gel solution (D), (5) adding the gel solution (D) into stainless steel hydrothermal synthesis reactor, increasing the temperature to 100-200° C for 24-240 hours, centrifuging the resulting product, washing and drying. The structure directing agent in step (1) is ammonium bromide compounds. USE - Method for inducing the preparation of two-dimensional magadiite/graphene oxide nanosheet composites. ADVANTAGE - The method solves the problem of the uncontrollable morphology of the magadiite material synthesis method and the inability to precisely control the regularity and layer spacing of the layer structure. The structure-directing agent controls the layer spacing of magadiite, and uses graphene oxide nanosheets as the growth plane to further control the layer structure regularity of the magadiite nanosheets. The imidazole ring in the imidazole compound can be inserted into the crystal framework and control its pore structure and size. DETAILED DESCRIPTION - Method for inducing the preparation of two-dimensional magadiite/graphene oxide nanosheet composites involves (1) dissolving 0.50-0.90 g structure directing agent in 5.00-8.00 g water at 60-80° C, obtaining solution (A), (2) dissolving 1.40-1.50 g sodium hydroxide and 3.00-3.90 g sulfate source in 33.00 g water, obtaining solution (B), (3) adding 2.08-3.50 g silicon source and 3.00-4.00 g solution (B) to solution (A) obtained in step (1), adding 1-10 mL of graphene oxide nanosheet dispersion with a concentration of 1-50 mg/mL, obtaining gel (C), (4) increasing temperature of the gel (C) to 60-80° C, aging for 5-8 hours under stirring conditions, obtaining gel solution (D), (5) adding the gel solution (D) into stainless steel hydrothermal synthesis reactor, increasing the temperature to 100-200° C for 24-240 hours, centrifuging the resulting product, washing and drying. The structure directing agent in step (1) is ammonium bromide compound of formulae: C22H45-N+C5H8NBr-, C18H37-N+C5H8NBr-, C16H33-N+C5H8NBr-or C12H25-N+C5H8NBr-.
