A control method of Xichu release of guest molecules with mesoporous materials

The invention discloses a method for controlling the Xichu release of guest molecules with mesoporous materials, the method comprises the following steps: (1) preparation of mesoporous materials, mesoporous materials retain the surfactant micelles in the synthesis of raw powder; (2) the step (1) mesoporous materials prepared by adsorption of guest molecules at high temperature, stored at room temperature; (3) when using mesoporous materials release of guest molecules. The present invention through the soft temperature control variable to switch to space nano micelle adsorption and release of guest molecules, realize the storage and release of specific temperature under control; the invention reduces the calcination to remove the template steps to reduce the pollution of the environment, the cost is reduced; the invention can be used for guest molecules carrying, drug delivery, to improve the micro environment of complex system; the invention adopts MCM-48 mesoporous molecular sieve in simulated gastric acid solution synthesis of 353K powder after the adsorption of NO in the most able to release 38.13 mol - g-1 NO.
