Synthesis of hollow silica particles with tunables ize,shell thickness,and morphology

Kim J., Lee J., Chang H., Choi J.W., Jang H-D, Kim J., Korea Institute of Geoscience and Mineral Resources, KR

Here, we provide simple methods to modify the particle size, shell thickness, and the morphology of hollow silica particles (HSPs). To synthesize the HSPs, we adopted polystyrene (PS) particles as a sacrificial template. Size tune [...]

Synthesis of Porous Nanostructured Silica Particles by an Aerosol Templating Method

Jang H-D, Chang H., Park J.H., Kim T-O, Okuyama K., Korea Instittute of geoscience and Mineral Resources, KR

Silica nano-materials with meso- and macroporosity are of great interest due to their variety of potential applications. For the application as a catalytic supporter, nanostructured spherical silica particles having both mesopores and macropores were prepared [...]
