  • Porous silica having high pore volume and methods of making and using same
    Patent number: 9943826
    Abstract: Silica particles, and methods of making and using silica particles are disclosed herein. In some embodiments, the silica particles are hollow, include an outer shell portion having a mesoporous structure, and have a pore volume of at least 4 cm3/g. In some embodiments, the silica particles include an outer shell portion having a mesoporous structure forming a cavity, the silica particles have an average pore diameter of 3 to 100 nm, and at least a portion of the silica particles include one or more core nanoparticles within the cavity. Silica particles as disclosed herein can be useful in a wide variety of applications such as selective separations (e.g., gas separations or purifications) based on structure.
