    Organic Frameworks Promotes Capacitive Deionization

## Description

- description: Covalent organic frameworks (COFs) are promising high-performance capacitive
    deionization (CDI) materials. Strategies to optimize CDI performance of COFs focus
    largely on hybridization with conductive substrates, to improve their their intrinsically
    poor conductivity. A new structure-function relationship between COFs and their
    substrates is proposed here based on substrate-induced surface curvature. Graphene
    (zero-curvature) and carbon nanotubes (CNT, curved) are selected as COF growthsubstrates
    to assess the effect of curvature engineering effect on CDI performance of TpPa-SO3H-COF.
    Ultrahigh ion (Na+) adsorption capacity (58.74 mg g−1) is achieved by CNT-COF
    hybrid (cf. compared to graphene-COF hybrid 34.20 mg g−1), demonstrating the significance
    of curvature engineering. Notably, the corresponding salt (NaCl) adsorption capacity
    of CNT-COF hybrid reaches 149.25 mg g−1 in 1000 ppm at 1.2 V, representing state-of-the-art
    CDI performance, and the highest value among organic CDI electrodes. X-ray photoelectron
    spectroscopy and theoretical calculations subsequently reveal that substrate curvature
    can induce local strain, which regulates charge distribution within the COF skeleton,
    causing a lower binding energy state for Na+ adsorption. Electrochemical quartz
    crystal microbalance measurements revealed faster Na+ adsorption kinetics of CNT-COF
    due to regulated charge distribution within COF skeleton induced by substrate
    curvature. This work gives new insight into design of COF materials based on curvature
    engineering.
