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.
