Enhanced Interfacial Charge Transport of Ni Metal–Organic Framework Nanosheets Interconnected by Carbon Nanotubes for Capacitive Deionization
Source abstract
Abstract
Metal–organic frameworks (MOFs) have shown significant potential in hybrid capacitive deionization owing to their unique structure and adjustable pore size. However, their limited electronic conductivity and electrochemical stability hinder their practical application. In this study, we developed hierarchically structured Ni-MOF nanosheets interconnected by carbon nanotubes (Ni-MOF@CNT) through a one-pot hydrothermal reaction. By combining the porous structure of Ni-MOF with the synergistic effect of Ni 2+ ions and CNTs, the Ni-MOF@CNT electrode with fast interfacial charge transfer demonstrates a high desalination capacity of 47.58 mg g –1 and excellent cycling stability. Additionally, the Ni-MOF@CNT electrode demonstrates a remarkable Li + ion extraction capacity of 30.29 mg g –1 .
