Germanium Dioxide Nanocubes with Different Size Distributions and Its Gibbs Free Energy Theory
A simple synthesis method for single crystal GeO2 nanocubes in a reverse micelle system was reported here. Hydrolysis of germanium tetrachloride (GeCl4) in a micelle system produces GeO2 nanocubes in the presence of oleylamine and cetyltrimethylammonium (CTAB). We found that we could obtain GeO2 nanocubes with monodisperse size distribution, bimodal size distribution and polydisperse size distribution by varying the reaction parameters. We put forward a feasible explain for this phenomenon with using Gibbs free energy theory, and this theory can give some meaningful guidance for preparing monodisperse nanomaterials.
