Title:
Non-destructive transmission electron microscopy study of catalyst degradation under electrochemical treatment 
Abstract:
A novel, nondestructive TEM technique is introduced, which enables the observation of the identical locations of a catalyst before and after electrochem. treatment (IL-TEM). The significance of this method is exemplified by the anal. of a std., com. available C supported Pt catalyst. The obsd. changes of the catalyst particles are a direct consequence of the applied electrochem. treatment; and selected catalyst regions are representative for the catalyst as a whole. Different electrochem. treat...    »
