Cobalt‐Based Catalyst Integration Into a Hierarchically Ordered Macro‐Meso‐microporous Carbon Cathode for High‐performance Aqueous Zn‐Sulfur Batteries

Advanced Science, EarlyView.
The ordered macro‐microporous carbon material (OM‐PC) with integration of Co3ZnC/Co catalyst is derived from a Co‐doped ZIF‐8 via in situ growth within the interstitial spaces of a self‐assembled polystyrene monolith. The hierarchical 3D architecture facilitates Zn2⁺ diffusion, and the Co3ZnC/Co catalyst significantly improves the affinity of the ...
