Enhanced photocatalytic activities of net-like hematite nanoparticle/graphene oxide composite

A facile strategy was developed to fabricate net-like hematite nanoparticle/graphene oxide (GO) composite (NHG), in which the degree of oxidization of GO could be controlled by simply changing annealing time. NHG with GO of appropriate oxidization degree and content exhibited much higher photocatalytic activities than α-Fe2O3 nanorods and commercial α-Fe2O3.
