- Abstract
- The formation of Ga-Pt particles and their simultaneous embedment in graphene layers was performed by sonication of molten gallium in an aqueous solution of H2PtCl6 in the presence of graphene. X-ray analysis of the dry particles revealed that their composition was GaPt3 and GaPt2. The synthesized Ga-Pt/G was examined as an electrode material for methanol oxidation reaction (MOR) and oxygen reduction reaction (ORR). This novel electrode showed better activity for MOR and ORR than a commercial Pt/C catalyst. © 2016 Elsevier Ltd. All rights reserved.
