 note = {This article in Japanese reviews our recent paper,“Rapid and high yield synthesis of hollow silica nanoparticles using an NH 4 F catalyst”, published in Colloids and Surfaces A: Physicochemical and Engineering Aspects 446, 46-49, (2014) by C. Takai, T. Ishino, M. Fuji and T. Shirai. The rapid synthesis of hollow silica nanoparticles based on the CaCO 3  template method is proposed. Typically, it contains two steps for the silica coating on a CaCO 3  template by a sol-gel reaction and template removal by a dilute acid solution. To promote the conversion of tetraethoxysilane (TEOS) to a silica shell on the CaCO 3  template, the effects of fluoride catalysts on the TEOS consumption rate during the silica coating were investigated using energy dispersive spectroscopy (EDS). The TEOS consumption rate of the NH 4 F-catalyzed system reached 100% within 15 min while the conventional NH 4 OH system took 120 min to consume the TEOS. The obtained samples using the NH 4 F system for 15 min showed a uniform hollow structure with a thin silica shell. For the KF system as the other fluoride catalyst, the TEOS consumption rate did not reach 100% even after 120 min. When the polystyrene (PS) template was used with the NH 4 F system, dense silica particles were formed as well as hollow structures. Based on these results, a rapid and high yield of hollow silica nanoparticles can be achieved by not only F- , but also NH 4+  using the CaCO 3  template method., application/pdf},
