Morphology evolution of Co phosphate and their electrochemical and photocatalytic performance

Abstract

Cobalt phosphate with different composition and morphologies were prepared via a one-step hydrothermal method. Interestingly, a novel morphology as self-curled cotton piece consisted of nanobelts was created by optimized preparation conditions. It is found that the amount of hexamethylenetetramine (HMT) and the ratio of mixed solvent affected greatly the morphology, size and phase component. The morphology was changed from flower-liked to cotton by changing the amount of HMT. As increasing the ratio of ethanol, the morphology changed from flower-liked nanosheet to cotton cluster nanobelt, the aspect ratio gradually increased, and the phase composition changed from cobalt phosphate octahydrate to cobalt phosphate tetrahydrate. In addition, the electrochemical properties and photocatalytic performance of samples were investigated. The results show that Co-based phosphate revealed fine capacitance behavior and cycle stability, and enhanced photocatalysis degradation for Rhodamine B in visible light range.
