合成了咪唑骨架8（Zn（MeIM）2，MeIM = 2-甲基咪唑; ZIF-8）/氧化石墨烯衍生的氮掺杂碳片，其对I3-还原为I-具有上级电催化活性.作为染料敏化太阳能电池的对电极，N掺杂碳纳米片的功率转换效率达到8.2%，高于Pt对电极的7.6%。这项工作表明，精心设计的碳材料是低成本染料敏化太阳能电池无金属对电极的有希望的候选材料。
Zeolitic imidazolate frameworks-8 (Zn(MeIM)2, MeIM = 2-Methylimidazole; ZIF-8)/graphene oxide derived N-doped carbon sheet has been synthesized, which exhibits superior electrocatalytic activity for the reduction of I3−to I−. As the counter electrode in dye-sensitized solar cells, a power conversion efficiency of 8.2% has been achieved for N-doped carbon nanosheet, which is higher than that of Pt counter electrode 7.6%. This work demonstrates that carefully designed carbon material is a promising candidate as the metal-free counter electrodes for low-cost dye-sensitized solar cells.
