However, the rapid volatilization severely influences their storage,application and quality. Therefore, it is necessary and urgent to develop approaches to controllably release the odorants as demanded. In this study, photo-driven mesoporous silica nanospheres loaded with sandela 803 was designed, prepared and named as S803@MS-S. S803@MS-S possessed ordered mesoporous, large specific surface area and pore volume. After adsorption of sandela 803, the S803@MSS was added into wallpaper to prepare fragrant wallpaper S803@MS-S-W. And this wallpaper exhibited excellent sustained and controlled release performances stimulated by light.展开更多
