Facile shape control of nano-coaxial Co₃O₄/TiO₂ arrays and the effect of the microstructure on lithium storage capability

Abstract

Co3O4/TiO2 nanohybrids fabricated via a layer-by-layer procedure have exhibited excellent electrochemical performance.

Co3O4 hollow nanospheres/carbon-assembled mesoporous polyhedron with internal bubbles encapsulating TiO2 nanosphere for high-performance lithium ion batteries

“…Therefore, hybridizing Co 3 O 4 and TiO 2 becomes an effective strategy to achieve superior overall performance since it takes advantage of high specific capacity of Co 3 O 4 and good stability of TiO 2 . So far, some Co 3 O 4 -TiO 2 -based hybrid have been researched, for example, hierarchical graphene-wrapped TiO 2 @Co 3 O 4 coaxial nanobelt arrays [33], honeycomb-spherical Co 3 O 4 -TiO 2 [34], wreath-like Co 3 O 4 @TiO 2 [35], nano-coaxial Co 3 O 4 /TiO 2 arrays [36]. They all exhibited good lithium storage performance.…”
