Core–shell-structured nanoporous PtCu with high Cu content and enhanced catalytic performance

A core-shell-structured bimetallic nanoporous PtCu catalyst with a high non-noble metal content (Cu: similar to 55 at%) and uniformly distributed ultrafine ligaments ( similar to 3 nm) is fabricated by one-step dealloying a well-designed Pt sub(4)Cu sub(21)Mn sub(7 5) single-phase ternary precursor...
