Evolution of Platinum Hierarchical Microstructure Amine - Assisted Growth via Solvothermal Method

摘要

Here we studied the formation of Platinum hierarchical microstructure by varying the synthesis time using amine assisted growth via solvothermal method. A small cluster of particles was produced at a shorter synthesis time (5h) while fully grown flower-like microstructure were formed at 9h of reaction. The synthesized Pt particles exhibit high absorption peak at 230 nm corresponding to Pt absorption peak. The catalytic property of the synthesized Pt is greatly influenced by its geometrical shape. The fully grown flower-like particles exhibit large electrochemical surface area (4.88 cm~(-2) g~(-1)) and catalytic stability at a longer period, which can serve as a potential catalyst for electro-oxidation of formic acid.
