The mophology control of hollow tubular cobalt-manganese spinel toward catalytic oxidation of toluene

Abstract In today’s context, the production of nanomaterials with different morphologies is a crucial concern, holding significant importance for catalytic efficiency and real-world usage. In this study, hollow tubular cobalt-manganese spinel prepared by electrospinning technology was used for the catalytic oxidation process of toluene. The lower calcination temperature (single phase) has lower crystallinity, and can provide better catalytic activity, where the sample calcined at 600°C can reach 90% toluene conversion rate with 1000 ppm toluene concentration at 310°C. This study provides a new understanding of the effect of spinel oxide morphology control on the oxidation ability of toluene, and provides a new structural control method for improving the oxidation ability of VOCs.
