Prussian blue-derived synthesis of uniform nanoflakes-assembled NiS₂ hierarchical microspheres as highly efficient electrocatalysts in dye-sensitized solar cells.

ABSTRACT: It's urgent and challenging to explore cost-effective and robust electrocatalyst in the development of large-scaled dye-sensitized solar cells (DSSCs). In this work, we develop a novel strategy to prepare 3D hierarchical NiS₂ microspheres constructed by nanoflakes through a facile chemical etching/anion exchange reaction. Nickel-cobalt Prussian blue analogous (PBA) nanocubes and (NH₄)₂S are employed to initially produce uniform γ-NiOOH/NiS _x hierarchical microspheres, which were then converted to uniform 3D hierarchical NiS₂ microspheres by a controlled annealing treatment. Due to their favorable structural features, the as-obtained NiS₂ hierarchical microspheres possess large surface areas, high structural void poros
