초록

The rational design of porous materials with high electrical conductivity is critical for optimizing their performance in energy-storage applications. In this study, we synthesize a partially reduced graphene oxide-encapsulated metal-organic framework (MOF) by following a facile self-assembly strategy to ensure intimate contact between the graphene oxide layer and the MOF while preserving the intrinsic porosity of the latter. Surface functionalization of the MOF with 3-aminopropyltriethoxysilane facilitates the controlled deposition of graphene oxide layers, preventing pore blockage and allowing uniform encapsulation. Unlike conventional MOF-based composites that suffer from pore blockage or agglomeration, this approach preserves open ion-diffusion pathways while enabling efficient charge transport. The encapsulated graphene layers exhibit a reduced number of oxygen functional groups and increased Csp2 content, enhancing electron conductivity and structural stability. Characterization results confirm that partially reduced graphene oxide encapsulation preserves the microporous framework of the MOF, considerably enhancing its electrical conductivity while preserving its porosity.
