摘要: Abstract Hierarchically porous sulfur-containing activated carbons were prepared by ice-templating from an aqueous sodium poly(4-styrenesulfonate) (Na-PSS) solution followed a single 800 °C pyrolysis step. This thermal treatment induced crosslinking, with the in-situ generation of Na2SO4 (activating agent), before carbonization and activation. The also resulted in formation sulfur salts, which could be converted to elemental upon simple HCl acid wash. content monoliths measured microanalysis increased 17.07 wt. % 39.74 wt. incorporating additional into prior pyrolysis. was uniformly dispersed within micropores carbon, selectively removed degassing (heating under vacuum) at different temperatures, revealing specific surface areas up 1051 m2 g−1. materials characterized various techniques evaluated for their potential as cathode lithium–sulfur battery. work may open new facile routes prepare applications where its presence is beneficial.
