Title:
酸素還元反応のための金属間Ｌ１０－ＮｉＰｔＡｇ触媒
Document Type and Number:
Japanese Patent JP7411533
Kind Code:
B2
Abstract:
An electrode catalyst for an oxygen reduction reaction including intermetallic L10-NiPtAg alloy nanoparticles having enhanced ORR activity and durability. The catalyst including intermetallic L10-NiPtAg alloy nanoparticles is synthesized by employing silver (Ag) as a dopant and annealing under specific conditions to form the intermetallic structure. In one example, the intermetallic L10-NiPtAg alloy nanoparticles are represented by the formula: NixPtyAgz wherein 0.4≤x≤0.6, 0.4≤y≤0.6, z≤0.1.
