Hybrid Nanostructures: Co–Fe Alloy/N‐Doped Carbon Hollow Spheres Derived from Dual Metal–Organic Frameworks for Enhanced Electrocatalytic Oxygen Reduction (Small 13/2019)

Transition metal/carbon-based composite materials have been considered as promising electrocatalysts for the oxygen reduction reaction (ORR). In article number 1805324, Bu Yuan Guan, Xiong Wen (David) Lou, and co-workers report a dual-metal–organic framework-assisted pyrolysis strategy to synthesize cobalt-iron alloy/N-doped carbon hollow spheres. Benefiting from the abundant bimetallic active sites and porous conductive matrix, the unique alloy/carbon-based materials manifest excellent electrocatalytic performance with enhanced activity and stability.
