title: A {0001} faceted single crystal NiS nanosheet electrocatalyst for dye-sensitised solar cells: sulfur-vacancy induced electrocatalytic activity.
abstract: Hydrothermally synthesised single crystal NiS nanosheets with an exposed (0001) surface exhibited a light conversion efficiency of 8.62% as an electrocatalyst for dye-sensitised solar cells (DSSCs), significantly higher than that of Pt-based DSSCs (7.36%). The theoretical calculations revealed the exposed (0001) surface with superior catalytic activity owing to the existence of sulfur vacancies.
