A novel approach based on vapor-phase transport technique using Au-coated plant cell walls with metallic ions as the catalyst has been developed to synthesize ZnO nanostructures. It is shown that plant cell walls can serve as a well defined template to grow patterned nanostructures. Quite interestingly, it is found that the shape of the nanostructures can be controlled by the metallic ions used. For instance, with Au/Ni+ catalyst, a homogeneous distribution of nanodendrites is obtained. On the other hand, with Au/Fe+ catalyst, nanotowers are observed. Morever, the Raman scattering spectra show excellent crystalline quality of the grown nanostructures. Our approach provides a low cost method, which is capable of the mass production for growing patterned nanostructures.
