【 摘 要 】

tsA 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.
