  The development of wet-chemistry methods leads to the blossom of research in materials with heterogeneous nanostructures, which usually exhibit improved catalytic properties due to the synergistic effect among their different domains or constituent materials. We herein would systematically introduce the latest research developments in palladium-based nanomaterials with core-shell, hollow, dendritic, or composite structures, and their potential applications as electrocatalysts for direct formic acid fuel cell reactions, including formic acid oxidation reaction and oxygen reduction reaction in acidic conditions, aiming at the summarization of the fundamentals and technical approaches in synthesis, fabrication and processing of palladium-based heterogeneous nanomaterials so as to provide the readers a systematic and coherent picture of the filed. This review will focus on the intrinsic relationship between the catalytic properties and the physical/chemical effects in the palladium-based heterogeneous nanomaterials, providing for technical bases for effectively developing novel electrocatalyts with low cost, enhanced activity and high selectivity.
