V-modified Co3O4 nanorods with superior catalytic activity and thermostability for CO oxidation

Abstract

As is well-known, Co3O4 nanomaterials with high catalytic activity can be easily deactivated in high temperature condition, which further inhibit their practical application in catalysis for CO oxidation. Herein, we reported a facile solvent-free strategy to synthesize V-modified Co3O4 nanorods. V-modified Co3O4 nanorods (without pretreatment) showed superior catalytic activity for CO oxidation in normal feed gas, and 100% CO conversion can be achieved at lower temperature of 60oC. Additionally, the incorporation of V into Co3O4 nanorods can remarkably enhanced the sintering resistance performance in high temperature condition. Compared with unmodified Co3O4 nanorods, V-modified Co3O4 nanorods exhibited outstanding thermostability in the catalytic process, due to the strong interaction between V and Co, which provided a promising way for developing the catalysts of CO oxidation with excellent anti-inactivation performance that is suitable for practical application.
