Abstract
HighlightsA strong interfacial chemical interaction between the NiSe2 nanocrystal and Ti3C2Tx MXene nanosheet (NiSe2/Ti3C2Tx) was established by wrapping NiSe2 octahedral crystal with ultrathin Ti3C2Tx MXene nanosheet.NiSe2/Ti3C2Tx hybrid exhibits excellent performance and cycling stability both in supercapacitor and hydrogen evolution reaction.NiSe2 nanocrystals are stabilized by the covering of Ti3C2Tx MXene nanosheet which served as a protective layer from its oxidation.
Highlights
With the development of society, the energy crisis has become more and more prominent; developing strate‐ gies toward high efficient energy storage and energy con‐ version has caught much attention [1, 2]
The results show that the hybridized N iSe2/ Ti3C2Tx displays excellent performances with capacity of 531.2 F g−1 at 1 A g−1 for supercapacitors, which is among the highest performances of the modified metal selenides [49, 50], and it exhibits relatively smaller Tafel slope of 37.7 mV dec−1 for hydrogen evolu‐ tion reaction (HER), which is close to the value of Pt
Further investigations have reviewed that these high perfor‐ mances of N iSe2/Ti3C2Tx are owing to the unique structure of the hybrid in which the T i3C2Tx MXene is evenly wrapped on the surface of the NiSe2 octahedral crystal via an interfa‐ cial interaction
Summary
Nano-Micro Lett. (2019) 11:31 strong interfacial interaction between NiSe2 octahedral crystal and Ti3C2Tx MXene, which provides enhanced conductivity, fast charge transfer as well as abundant active sites, and highlight the promising potentials in combinations of MXene with metal selenides for mul‐ tifunctional applications such as energy storage and conversion.
