Iron pyrite has long been an attractive material for environmental and energy applications, but is hampered by a lack of control over morphology and purity. Hollow porous iron pyrite nanoparticles were synthesized by a direct sulfurization of iron oxide derived from Prussian blue. The high efficiencies of these hollow porous iron pyrite nanoparticles as effective dye-sensitized solar cell counter electrodes were demonstrated, with an efficiency of 7.31 %.
长期以来，黄铁矿一直是环境和能源应用领域颇具吸引力的材料，但因形态和纯度难以控制而受到限制。通过对普鲁士蓝衍生的氧化铁进行直接硫化，合成了中空多孔黄铁矿纳米颗粒。这些中空多孔黄铁矿纳米颗粒作为有效的染料敏化太阳能电池对电极，展现出了高效性，效率达7.31%。
