Hexagonal and vertically aligned La(OH)(3) nanorod arrays have been fabricated in a large scale via a simple electrochemical method without any hard templates and surfactants. By the aid of potential-time curve, a possible formation process of the La(OH)(3) nanorod arrays is proposed, and the gas bubbles functioning as a dynamic template might be responsible for the growth of ordered La(OH)(3) nanorods. The total absorption capacities of the as-prepared products for Congo red is about 73.5 mg g(-1), which shows an environmental engineering application in removing organic dye from water. In short, this synthetic method shows prominent advantages such as its low-cost, easy preparation, good adherence and suitability for preparing other nanoarrays.
