Graphene/ZnO-Bi2O3 nanoplates (GZB) were prepared by means of the low temperature hydrothermal method, and their photocatalytic activity for degradating rhodamine B (RhB) was studied. Experimental results show that the ZnO-Bi2O3 nanoparticles were supported on graphene sheet under the assist of cetyltrimethylammonium bromide (CTAB). Furthermore, the resultant GZB nanoplates exhibited very strong adsorption capacity and high photocatalytic activity, in which the first absorbed ability comes up to about 74.62% within 30min. Moreover, 90% RhB in solution can be degraded within 100min under visible light after the sample reach the maximum adsorption.
