Spherical to polyhedral Pt nanocrystal formation assisted with methylamine
Nanocrystalline Pt particles synthesized by solvothermal technique assisted with methylamine were investigated. The effect of different amounts of methylamine on the formation of Pt nanocrystal were characterized and elaborated. Small and spherical - like particles were observed for Pt synthesized under the low amount (0.10 mL) of methylamine whilst, concave polyhedral Pt nanocrystal with high - index {411} facets were observed for Pt synthesized under high amount (0.20 mL) of methylamine. The synthesized concave Pt nanocrystal exhibit high absorption peak at 215 nm corresponding to colloidal Pt. The synthesized concave polyhedral structures could be used as a potential catalyst in fuel cells application.
