Abstract

Abstract : Chemical grafting of nanoscale UIO-66 onto polypyrrole nanotubes (sesame-like PPyNTs@UIO-66) was performed successfully, and the corresponding PPyNT@UIO-66-S cathode greatly improves the cycling performance of lithium–sulfur batteries. Abstract : A versatile strategy for a facile approach to chemical graft MOFs onto polypyrrole nanotubes (PPyNTs@MOFs) is designed and fabricated rationally by means of 1, 4-dibromobutane linkage. Various MOFs arranged randomly close-packed on PPyNTs, including Co 2+, Cu 2+, Zn 2+, Mn 2+, Fe 3+, Al 3+, Ti 4+, Cr 4+, Zr 4+ and V 4+, have been synthesized successfully. The as-prepared PPyNT@UIO-66 hybrids, used as a cathode carrier, exhibit excellent cyclic stability in Li–S batteries via strong physical and chemical adsorption/affinity with polysulfides.
