- •
Dual integration system endowing two dimensional TiS2 nanosheets with enhanced electrochemical performance for I3− reduction is configured.
- •
The as-made TiS2-graphene (TiS2–G) hybrids as counter electrodes for DSSCs deliver a high power-conversion efficiency of 8.80%, outperforming Pt (8.00%).
- •
The high catalytic activity of TiS2–G hybrids is ascribed to synergetic effects derived from highly electroactive TiS2 species and conductive G matrix.
- •
Such a composite also manifests excellent electrochemical stability, indicative of great potential for Pt replacement.
