A novel lamellar-structured Co/Co(OH)(2) nanocomposite was synthesized with a room-temperature solution-phase reduction method. A possible reaction mechanism and shape evolutionary process for the Co/Co(OH)(2) nanocomposite were supposed. The Co/Co(OH)(2) nanocomposite shows a ferromagnetic behavior. Congo red (CR) was used to evaluate the Co/Co(OH)(2) nanocomposite wastewater treatment capability. It was found that 150 ppm of CR could be removed from an aqueous solution within 10 min using the Co/Co(OH)(2) nanocomposite, and the adsorption maximum is 2058 mg g(-1) which is higher than all previously reported values. The significantly reduced treatment time required to remove the CR and the simple, low-cost and pollution-free preparation method make the Co/Co(OH)(2) nanocomposite promising for use in the highly efficient removal of dyes from wastewater.
