Electrodeposited platinum catalysts over hierarchical carbon monolithic support

Mesoporous deposits of platinum catalysts were electrodeposited over monolith carbon with hierarchical porous structure. The liquid crystal used as a template allowed the electrodeposition of the catalyst on the outer region of the carbon with low penetration in the porous structure. The platinum he...
