Preparation of hollow spheres with controllable interior structures by heterogeneous contraction.
We present a simple and effective heterogeneous contraction method to fabricate hollow spheres with controllable interior structures (ranging from solid, simple hollow to core-in-hollow-wall, double-wall hollow and core-in-double-hollow-wall spheres) by a non-equilibrium heat-treatment process of gel precursors with a high heating rate.
