Adv. Mat. 29, 18841-18849 (2017)

A new class of multimetallic hierarchical aerogels composed entirely of interconnected Ni-PdxPty nano-building-blocks with in situ engineered morphologies and compositions is demonstrated. The underlying mechanism of the galvanic shape-engineering is elucidated in terms of nanowelding of intermediate nanoparticles. The hierarchical aerogels integrate two levels of porous structures, leading to improved electrocatalysis performance.
