Surface Activation of Pt Nanoparticles Synthesised by "Hot ...
Sep 01, 2015· Analysis of the catalyst activity, based on HCOOH oxidation, clearly shows that thermal pre-treatment in Ar with temperatures above 350 °C provides an optimum methodology for surface activation. Similar conclusions can be reached by estimating the electrochemical surface active area by oxidation of adsorbed CO (CO ads ), as discussed in the ...
