Resumen:
A high surface macroporous porous carbon (MPC) has been obtained by SiO2
nanoparticles template and further used as support for PtRu catalysts.
MPC supported PtRu materials show an enhanced activity for methanol
electrooxidation when compared with commercial catalysts. This
observation is discussed in terms of reactant accessibility to active
sites. The improved diffusion through the porous matrix influences not
only methanol feeding, but also removal of reaction subproducts, as
clearly shown by differential electrochemical mass spectrometry (DEMS).
