In this communication we present an extremely rapid, simple and template-free method for the electrochemical fabrication of CoPt/gold nanosheet motors (NSMs) via a three-step applied potential process. The oxygen-propelled NSMs can be guided by a magnetic force in an aqueous solution containing 1% hydrogen peroxide as fuel. Finally, the catalytic activity of the prepared NSMs toward the degradation of rhodamin B (RB) and methylene blue (MB) was investigated as a model for environmental remediation.
