Abstract
- Unique and novel Pd 4 Sn nanochain networks were successfully synthesized with an average diameter of 5 nm, rendering a modified Pd electronic structure with rich defects such as atomic corners, steps or ledges as catalytic active sites for great enhancement of charge transfer and electrode kinetics. The prepared Pd 4 Sn nanochain networks held an electrochemically active surface area as high as 119.40 m 2 g −1 , and exhibited higher catalytic activity and stability toward formic acid oxidation compared with Pd 3 Sn nanochain networks, Pd 5 Sn nanochain networks, Pd 4 Sn dendrites and Pd/C. The fundamental insight of the enhancement mechanism is discussed, and this work offers a novel, less expensive but highly active catalyst for direct formic acid fuel cells. [ABSTRACT FROM AUTHOR]
