A Comparative Study of Photodegradation Behavior Sodium Niobate Nanowires and Microcubes

Sodium niobate catalysts with different morphologies of nanowires and microcubes have been prepared by hydrothermal method. The photocatalytic performance of NaNbO3 nanowires and microcubes was evaluated by degradation of rhodamine B (RhB) and cationic red X-GRL (CRX). The photodegradation reaction of organic dyes is shown to be kinetically first-order. The as-prepared NaNbO3 nanowires exhibit higher photo-catalytic activity for organic dyes degradation than NaNbO3 microcubes, which is attributed to the larger specific surface area and ferroelectric phase structure.
