Abstract
Nanoporous (NP) PtFe alloys with two different bimetallic ratios are fabricated by selectively dealloying PtFeAl ternary alloys, characterized by nanoscaled bicontinuous network skeleton with interconnected hollow channels extending in all three dimensions. With the ligament size as small as 5Â nm, NP-PtFe alloys show superior electrocatalytic activity towards oxygen reduction reaction with enhanced specific and mass activities as well higher structure stability compared with PtFe/C and Pt/C catalysts.377
