Title: | A TiC@TiO2-C Support for Pt Catalysts to Boost the Oxygen Reduction Reaction | Authors: | Zheng, Cheng Sun, Xueqin Qin, Yanxi Li, Junfeng Jin, Guoqiang Tong, Xili YANG, Nianjun |
Issue Date: | 2023 | Publisher: | WILEY-V C H VERLAG GMBH | Source: | Advanced Sustainable Systems, | Status: | Early view | Abstract: | The design of advanced supports to boost the oxygen reduction reaction (ORR) in acidic media is of great significance for proton exchange membrane fuel cells. Herein, TiC@TiO2-C supports are prepared by the sol-gel method coupled with high-temperature annealing. The obtained Pt/TiC@TiO2-C catalyst exhibits outstanding ORR activity such as the half-wave potential of 0.84 V-RHE as well as strong electrochemical stability in 0.1 m HClO4 electrolyte, surpassing the Pt/TiO2-C and Pt/C catalyst. This result is attributed to the electron transfer from the support to Pt nanoparticles accelerated by the TiC core, which optimizes the electronic structure of Pt to boost the ORR. | Notes: | Tong, XL (corresponding author), Chinese Acad Sci, State Key Lab Coal Convers, Inst Coal Chem, Taiyuan 030001, Peoples R China.; Yang, NJ (corresponding author), Hasselt Univ, Dept Chem, Agoralaan 1, B-3590 Diepenbeek, Belgium.; Yang, NJ (corresponding author), Hasselt Univ, IMO IMOMEC, Wetenschapspk 1, B-3590 Diepenbeek, Belgium. tongxili@sxicc.ac.cn; nianjun.yang@uhasselt.be |
