Abstract
Platinum nanoparticles were prepared in ethanol by electric discharge method. The absorption of platinum nano-colloid was measured by UV–Visible Spectrophotometer (UV–Vis). Measurement of Zetasizer showed that the zeta potential is − 40.8 mV, representing the good suspension of platinum nano-colloid with a size of nanoscale. Platinum nano-colloid was identified by X-ray diffraction and Raman spectrometer. Transmission electron microscope (TEM) was used to observe the actual distribution of platinum nanoparticles. The results show that size of platinum nanoparticles are divided into three groups. Size distribution of 3 nm accounts for the majority, which is similar to the results of chemical preparations. The well distribution of platinum nanoparticles was observed clearly without precipitation by TEM.
