Morphological control by magnetic fields : The application of magnetic fields is found to result in fluctuation of the energy of the Co 3 O 4 crystal surface, which hinders the growth of {100} faces, and thus leads to the preferred formation of Co 3 O 4 nanocubes. However, in the absence of external magnetic fields during synthesis, only irregular Co 3 O 4 nanospheres can be obtained (see graphic).
