Synthesis of nano hollow Zinc phosphate using soft-template method
Abstract
This study focuses on the synthesis of nano hollow zinc phosphate using soft - template method through precipitation of Zn(NO3)2 and (NH4)2HPO4. A surfactant of 1,1,1-tris(hydroxymethyl) propane (TMP) was applied as the template for synthesizing process. In addition, n-octanol – a co-surfactant was also added to solution in order to study the interaction between the two surfactants. Two reaction parameters including temperature (0, 15, and 30oC) and pH 8.5were respectively examined to figure out the optimal condition for synthesis. The TEM results showed that hollow zinc phosphate nano particles with size of 20 - 50nm formed at the conditions of 0oC and pH of 8.5. It could be realized that the hollow nano material was favorable to create at low temperatures. Particularly, the presence of n-octanol made the nano hollow zinc phosphate obviously decrease in size.
