【 摘 要 】

tsHigh-index faceted Fe2O3 nanocrystals with abundant unsaturated Fe sites not only have strong adsorption capacity to anchor LiPSs but also have superior catalytic activity to facilitate the redox conversion of LiPSs and reduce the decomposition energy barrier of Li2S.Our work deepens the comprehending of facet-dependent activity of catalysts in Li–S chemistry and affords a novel perspective for the design of advanced sulfur electrodes.
