| description | The chemical composition and surface groups of the carbon support affect the adsorption capacity of toluene. To investigate the effect of catalyst substrate on the catalytic performance, two different plant biomasses, banana peel and sugarcane peel, were used as carbon precursors to prepare porous carbon catalyst supports (Cba, Csu, respectively) by a chemical activation method. After decorating PtCo<sub>3</sub> nanoparticles onto both carbon supports (Cba, Csu), the PtCo<sub>3</sub>-su catalyst demonstrated better catalytic performance for toluene oxidation (T<sub>100</sub> = 237 °C) at a high space velocity of 12,000 h<sup>−1</sup>. The Csu support possessed a stronger adsorption capacity of toluene (542 mg g<sup>−1</sup>), resulting from the synergistic effect of micropore volume and nitrogen-containing functional groups, which led to the PtCo<sub>3</sub>-su catalyst exhibiting a better catalytic performance. Moreover, the PtCo<sub>3</sub>-su catalyst also showed excellent stability, good water resistance properties, and high recyclability, which can be used as a promising candidate for practical toluene catalytic combustion. |
