Large scale and uniform La(OH)3 nanorods prepared by template-free pulsed electrodeposition method

Abstract

Pulse deposition was applied, for the first time, in the cathodic electrodeposition of La(OH)3 from La(NO3)3 nitrate bath. The deposition experiments were performed at the pulse current mode with a typical on-time and off-time (ton=10ms and toff=50ms) and an average current density of 0.5mAcm−2 (Ia=0.5mAcm−2). Large-scale, uniform and well-defined single-crystalline nanorods of lanthanum hydroxide were prepared by this easy and template-free electrochemical method under mild conditions. It was concluded that the pulse cathodic electrodeposition can be recognized as a facile and efficient method for the synthesis of uniform La(OH)3 nanorods at large scale.
