Mesopores in Metal-Organic Frameworks Rendering Enhanced Rate Capability of Pore-Confined Polyaniline for Supercapacitors.

ABSTRACT: Polyaniline (PANI) has been extensively studied as a pseudocapacitive material for electrochemical energy storage, and the facile mass transfer of counterions in PANI during the electrochemical process is crucial to achieve the excellent rate capability of the corresponding supercapacitor. Nanoporous materials with rigid and interconnected pores are thus considered as attractive scaffolds of PANI to facilitate mass transfer. Herein, soft-template-assisted approaches are employed to synthesize a water-stable zirconium-based metal-organic framework (MOF), UiO-66-NH₂, with distinct hierarchical pore sizes. Three kinds of UiO-66-NH₂ nanocrystals with almost the same microporosity and specific surface area, but possessing large mesopores (15 nm), small mesopores (5-6 nm) a
