Paper Title:
Synthesis of Hollow Silica Particle by Combination of Bubble Templating Method and Sol-Gel Transformation
  Abstract

The feasibility of bubble templating method to prepare hollow particles was tested in this paper by passing a bubble into a silica sol. The silica sol was prepared by mixing TEOS, water, alcohol and hydrochloric acid. To control the gel point, the reactants and their concentrations were varied in each experiment. After the sol was prepared, an ammonia bubble was introduced into the prepared sol through a capillary tube. With the catalysis of ammonia, the silica sol gelled on the surface of bubble and formed a hollow gel particle. The nucleation of silica gel on the surface of bubble was discussed in this paper.
