The fabrication of Co2P-Co (Co-P composites) hollow nanospheres with graphene sheets decoration through one-pot solution approach is demonstrated and their potential as the anode materials for lithium ion batteries is assessed. A large specific capacity of 929mAhg−1 can be retained for Co-P/graphene nanocomposites at 100mAg−1 after 200 cycles. When cycled at a large current density of 2.0C, the Co-P/graphene...
Hybrid nanostructures containing multiple components have received intensive interests. Herein, we report a solution method for the preparation of Au–ZnO/graphene nanocomposites in which multi-branched Au–ZnO hybrid nanocrystals with ZnO nanorods growing on octahedral Au cores are anchored on graphene. The as-prepared hybrid nanocrystal and nanocomposite samples are characterized by transmission electron...
Crystallization of nanoparticles with different sizes into an ordered assembly provides an important means to construct nanostructure that may possess novel collective properties from nanoparticle interactions. In this study, we report the formation of bidisperse Au nanoparticle superlattices that are self-assembled from 4.3-nm and 7.3-nm monodisperse Au nanoparticles. Various self-assembly parameters...
