| 摘要： | Polyhedral CoOx was synthesized by calcination of Co-based metal-organic framework ZIF-67 and highly dispersed Pt nanoparticles were successfully loaded on CoOx. The catalytic results showed that Pt-nano/CoOx had the best activity and stability. As compared with conventional Co3O4, polyhedral CoOx showed more excellent catalytic oxidation performance of toluene, which was related to enhanced oxygen mobility, defective structure and rich active oxygen species provided by Polyhedral CoOx. Moreover, PtCoOx metal-support interaction enhanced the dispersion of Pt species and showed more Pt-0 ratio. It was reasonable that the gaseous O-2 can be activated directly or moved into the catalyst's surface to form oxygen cycle. (C) 2020 Elsevier Ltd. All rights reserved. |
