A novel technique for fabricating hollow silica spheres (see figure) via a one‐step process is described. The positively charged template polystyrene particles are “dissolved” subsequently, even synchronously, as the silica layer is formed in the same medium. Hollow silica spheres are formed, and neither additional dissolution nor calcination is needed during the whole process. The scale bar represents 1 μm.
