Abstract

Unraveling the influence of incorporating transition metal elements on layered transition metal chalcogenides for energy storage application remains a challenge. Herein, niobium (Nb)-doped layered titanium disulfide (TiS₂) is applied to generate novel compounds Ti_1−xNb_xS₂ (x=0.05, 0.1 and 0.20). Interestingly, TiS₃ nanobelts are formed in the resulting materials, which is proven by systematic morphological and structural characterization. It has been found that Nb-doped TiS₂ compounds demonstrate superior electrochemical capacitive activity, reaching up to a 63.2 % increase in gravimetric capacitance in 1 M Na₂SO₄ electrolyte compared with that of the Nb-free TiS₂. This remarkably enhanced capacity behavior is attributed to Nb doping resulting a structural transition of Layered TiS₂ to TiS₃ nanobelts.
