Abstract

original image

A smart hybrid nanowire array consisting of Co3O4 porous nanowire cores and MnO2 ultrathin nanosheet shells can be fabricated by a 3D interfacial carbon-assisted hydrothermal method, improving the pseudocapacitive energy-storage performance. The combination of MnO2 and Co3O4 with unique morphology and independent electroactivities into a single hierarchical architecture leads to high capacitance, remarkable cycle performance and rate capability, report Hong Jin Fan and co-workers on p. 2076.
