Mesoporous-graphitic-carbon-supported HfO2 (HfO2 -MGC) nanohybrids were synthesized by using a soft-template route. Characterization and a systematic investigation of the catalytic properties, stability, and catalytic mechanism were performed for HfO2 -MGC counter electrodes (CEs) in dye-sensitized solar cells (DSSCs). The new HfO2 -MGC as a CE in DSSCs showed a surprisingly high efficiency of 7.75 % for the triiodide/iodide redox couple and 3.69 % for the disulfide/thiolate redox couple, greater than the Pt electrode in the corresponding electrolyte system, which opens up a possibility for its practical application.
介孔石墨碳负载氧化铪（HfO2-MGC）纳米杂化物是通过软模板法合成的。对染料敏化太阳能电池（DSSCs）中 HfO2-MGC 对电极（CE）的催化性能、稳定性和催化机制进行了表征和系统研究。新型 HfO2-MGC 作为 DSSCs 的 CE，在三碘化物/碘化物氧化还原对中的效率高达 7.75%，在二硫代/硫醇氧化还原对中的效率高达 3.69%，优于相应电解质体系中的 Pt 电极，这为其实际应用开辟了可能性。
