Nano-ZnO/bamboo charcoal composites were prepared by precipitation with bamboo charcoal as support. Nano-ZnO/bamboo charcoal composites were characterized by XRD, SEM and EDS. Photocatalytic degradation processes of methyl orange were studied. The results indicate that the structure of nano-ZnO is of the wurtzite type and the grain size is about 19-54 nm. The best preparation temperature for these composites is 500℃. The composites have better photocatalytic degradation ability than pure ZnO under UV irradiation. Photocatalytic degradation of methyl orange with the composites obeys first-order kinetics, and the composites can be recycled.<p>DOI: <a href="http://dx.doi.org/10.5755/j01.ms.24.1.17397">http://dx.doi.org/10.5755/j01.ms.24.1.17397</a></p>
