Enhancing the performance of Co3O4/CNTs for the catalytic combustion of toluene by tuning the surface structures of CNTs

Co3O4/CNTs were prepared as catalysts for the catalytic combustion of toluene. The defects of CNTs facilitated the catalytic combustion conversion of toluene, and the COOH on CNTs could promote the selectivity to CO2. Thus, Co3O4/CNT catalysts demonstrated high catalytic performance, indicating a potential application for the catalytic combustion of VOCs.
