Abstract

From the inside out: Silica colloids can be spontaneously transformed from solid spheres to hollow structures in aqueous solutions of NaBH₄ (see picture). The high pH value and gradual decomposition of NaBH₄ facilitate the formation of hollow structures first by partial dissolution of silica cores and then by regrowth of the silicate species on the colloid surfaces to form shells. (Figure Presented).
