Engineering the dimensionality of porous Co3O4 for enhanced capacitive deionization performance

Abstract

The intricate network of pores within the material matrix is frequently underutilized during ion diffusion. Here, the spatial dimension of the ZIF-9 derived porous material was precisely controlled by strategic modification of the carboxyl functional groups on the ligand chains for deriving 2D-Co₃O₄ architecture, which demonstrates substantially enhanced accessibility to its porous domains, and consequently leads to markedly improved desalination capacity.
