Component-controlled synthesis of Pd_xSn_y nanocrystals on carbon nanotubes as advanced electrocatalysts for oxygen reduction reaction.

ABSTRACT: Pd-based bimetallic or multimetallic nanocrystals are considered to be potential electrocatalysts for cathodic oxygen reduction reaction (ORR) in fuel cells. Although much advance has been made, the synthesis of component-controlled Pd-Sn alloy nanocrystals or corresponding nanohybrids is still challenging, and the electrocatalytic ORR properties are not fully explored. Herein, component-controlled synthesis of Pd_xSn_y nanocrystals (including Pd₃Sn, Pd₂Sn, Pd₃Sn_2, and PdSn) has been realized, which are in situ grown or deposited on pre-treated multi-walled carbon nanotubes (CNTs) to form well-coupled nanohybrids (NHs) by a facile one-pot non-hydrolytic system thermolysis method. In alkaline media, all the
