Hierarchical MgFe-LDH microspheres with tunable interior structure have been synthesized by a facile and cost-effective surfactant-templated method. The obtained hollow MgFe-LDH microspheres exhibit excellent electrocatalytic oxidation of ethanol in alkaline fuel cell, including high activity, long-term durability and cycling stability, owing to the significantly improved faradaic redox reaction and mass transport
