The preparation of various metal oxides/hydroxides and their morphology control by a novel arc-discharge method

Abstract Metal oxide or hydroxide nanomaterials were synthesized by an arc-discharge method in an aqueous electrolyte, with different metal electrodes. The morphologies of the obtained nanomaterials were controlled successfully. From the results of XRD and TEM, it is obvious that different products had different morphologies under the same NaCl electrolyte.
