Co3O4 multilayered structures were successfully prepared using a thermal decomposition of precursorapproach.The precursor multilayered structures are synthesized by a facile chemical precipitation method.X-raydiffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the products.Results showthat time,temperature and surfactant play important roles in the formation of the products.The catalyticmeasurements reveal that the as-prepared Co3O4 particles plays a photocatalytic role on the degradation of methylorange.
