Abstract
Exploring active and durable Electrocatalysts is pivotal to the development of green energy conversion technologies, such as fuel cells, water splitting, CO2 reduction et al. Ultrafine 1D multimetallic nanowires are a class of intriguing electrocatalyst candidates, which present unique anisotropic characteristics and superhigh atomic exposures. Precise tuning of their elementa combination and distribution can offer great possibilities to optimize the electrochemical reactivities. In this talk, we focus on atomic-level constructions of precise surface/interface structures on ultrafine 1D multimetallic nanomaterials for electrocatalytic applications. We find that surface heteroatom pairs, oxide/metal inverse interfaces, atomic shell-thickness control as well as amorphous phase are effective strategies for improving the electrocatalytic activities and stabilities of ultrafine1D multimetallicnanowires.
