| 题目: | Pt-Co3O4-CDs electrocatalyst with enhanced electrocatalytic performance and resistance to CO poisoning achieved by carbon dots and Co3O4 for direct methanol fuel cell | | | | | 作者: | Yue Sun, † Yunjie Zhou, † Cheng Zhu, Lulu Hu, Mumei Han, Aoqi Wang, Hui Huang, * Yang Liu,* and Zhenhui Kang* | | | | | 单位: | Jiangsu Key Laboratory for Carbon-based Functional Materials and Devices, Institute of Functional Nano and Soft Materials (FUNSOM), Soochow University, Suzhou, China. | | | | | 摘要: | High efficient electrocatalysts remain huge challenges in direct methanol fuel cells (DMFCs). Here, the Pt-Co3O4-CDs/C composite was fabricated as anode electrocatalyst with low Pt content (12 wt%) by using carbon dots (CDs) and Co3O4 nanoparticles as building blocks. Pt-Co3O4-CDs/C composite catalyst shows a significantly enhanced electrocatalytic activity (1393.3 mA mg-1 Pt), durability (over 4000 s) and CO-poisoning tolerance. The superior catalytic activity should be attributed to the synergistic effect of CDs, Pt and Co3O4. Furthermore, the Pt-Co3O4-CDs/C catalyst was integrated into a single cell, which exhibits a maximum power density of 45.6 mW cm-2, 1.7 times of the cell based on commercial 20 wt% Pt/C catalyst. | | | | | 影响因子: | 7.76 | | | | | 分区情况: | 1区 | | | | | 链接: | http://pubs.rsc.org/en/content/articlelanding/2017/nr/c7nr01727h#!divAbstract 责任编辑:向丹婷 联系方式:dtxiang@suda.edu.cn |
