以葡萄糖为碳源、硫酸为脱水剂、聚苯乙烯胶体晶体为模板,采用简单的浸渍-煅烧工艺制备了高度三维有序大孔碳(3DOM-C)材料.利用SEM、FESEM、TEM、紫外-可见光光度计和氮气吸附-脱附分析仪对样品进行了表征,考察了3DOM-C、贵金属Pt和活性碳作为对对电极材料在染料敏化太阳能电池(DSSCs)中的光电转化性能,并进一步对电极进行了电化学阻抗分析.结果表明,3DOM-C材料的孔径约为280 nm,具有三维有序网络空间结构.J-V测试结果显示,3DOM-C/DSSC的光电转化效率为4.61％,达到了Pt/DSSC的90％.阻抗测试结果显示,3DOM-C电极表现出良好的电催化活性及导电性,与Pt电极相近且远高于活性碳.
