| 中文摘要 | the development of advanced support materials displays the potential for both reducing the cost and simultaneously increasing the activity of catalysts. in the current work, a novel n-doped carbon coated hydrophilic titanium dioxide (tio2@n-doped c) nano-composite, constructed by the procedure of an in situ polymerization and subsequent pyrolysis, was utilized to support pt nano-crystals for the methanol oxidation reaction (mor). the as-prepared pt/tio2@n-doped c catalyst generated 1.74-fold higher activity, 2.08-fold higher stability and much better resistance to co poisoning than a commercial state-of-the-art pt/c catalyst. the enhanced catalytic performance was ascribed to the improved co tolerance and the catalyst-support interaction due to the utilization of the tio2@n-doped c nano-composite, which not only provides rich active -oh groups to promote co oxidation via the bifunctional mechanism, but also modifies the electronic structure of the pt nps to improve the intrinsic kinetics of mor. the as-developed tio2@n-doped c nano-composite is a highly promising catalyst support material for use in fuel cell technology. |
