The present invention discloses a graphene oxide @ bio based porous silicon core-shell structure sustained-release container and its preparation method and application, including a core-shell structure composed of porous silicon and graphene oxide, as well as a corrosion inhibitor loaded on the shell structure; Among them, the core-shell structure includes a porous silicon core and a graphene oxide shell coated on the outer surface of the porous silicon core. GO ethanol dispersion was prepared by Hummer's method and solvent displacement method. At the same time, the bio based porous silicon obtained by straw combustion and the inhibitor benzotriazole were mixed and dispersed in ethanol solution. Then, GO ethanol dispersion was mixed with bio based porous silicon and BTA ethanol dispersion, and GO @ bio based porous silicon core-shell structure nano materials loaded with corrosion inhibitor BTA were prepared by spray drying method. The invention synthesizes GO @ biological porous silicon core-shell structure nanomaterial loaded with corrosion inhibitor through a simple spray drying method, which can be used as a slow release container to achieve efficient encapsulation and controllable slow release of BTA.
