A facile, low-cost and green ultrasound-assisted method was developed to ultra-fast synthesize Mn3O4 nanosheets supported on reduced graphene oxide (RGO). Such hybrid materials exhibited ultrahigh performance as lithium ion battery (LIB) anodes, whose specific capacity reached more than 1400 mA h g(-1) after 40 cycles at a current density of 100 mA g(-1) (based on the mass of Mn3O4). The remarkably enhanced LIB performance could be attributed to their layer-by-layer aggregation structures.

A facile and low-cost layer-by-layer technology has been developed to synthesize a multi-functional Au/CdS/Fe 3 O 4 /reduced graphene oxide (RGO) hybrid nanomaterial. The RGO nanosheets are indispensable, as they act not only as a supporter to hold the multiple components together, but also as an electron acceptor and transporter to efficiently hinder the recombination of the photogenerated electron-hole pairs.
