Pyrolytic waste tire char was modified to be used as support and a series of catalysts supported with 0.1–1.0 wt% Pt were prepared by conventional wetness impregnation method. TEM images show that the Pt nanoparticles are well-dispersed in any microregions in the sample view on the TEM grid. The results of methylcyclohexane dehydrogenation reaction show the Pt loadings and the reaction temperature have a significant impact on the catalytic activity.
► Purified carbon materials with high surface area were obtained via modification of pyrolytic waste tire char. ► The Pt nanoparticles (around 2.5 nm) are well dispersed on the surface of the carbon materials support. ► The Pt catalyst exhibites 100% selectivity and over 95% conversion on methylcyclohexane dehydrogenation reaction. ► The Pt loading and the reaction temperature have strongly effect on the performance of prepared catalysts.
