Copper nanoparticles Subject

There are a number of different ways to prepare metal overlayers in practical nanoscale fuel cell electrocatalysts. One approach is schematically shown in Figure 3.3.13A, where a spherical alloy nanoparticle consisting of a noble metal (grey), platinum, and a nonnoble metal (red), such as copper, is subject to a corrosive electrochemical... 

The TFM morphology of sodium stearate-coated Cu nanoparticles was investigated on a JFOL JFM-2010 transmission electron microscope at an acceleration voltage of 200 kV. The prepared powders were dispersed in chloroform under ultrasonic agitation for 20 min and then deposited on a copper grid covered with a perforated carbon film. The resulting specimen was then subjected to TFM analysis.
