Ultrasmall SnO2 nanocrystals sandwiched into polypyrrole and Ti3C2Tx MXene for highly effective sodium storage
Keyword(s):
A novel sandwich-type P-SnO2/Ti3C2 composite with superior sodium storage capability has been fabricated, where polypyrrole (PPy) layer modified SnO2 nanocrystals are strongly coupled with Ti3C2Tx Mxene nanosheets through Sn–O–Ti chemical bonds.
