“…2f ), two strong peaks at 781.1 and 797.3 eV correspond to the Co 2p 3/2 and Co 2p 1/2 orbitals of Co 2+ . 43 The accompanied satellites are located at 785.9 and 802.8 eV. In addition, the spectrum of Ti 2p (Fig.…”

Review of Pristine Metal–Organic Frameworks for Supercapacitors: Recent Progress and Perspectives

“…116 The partially exfoliated graphite paper (EGP) composed of graphene nanosheets can act as an ideal conductive substrate for growing MOFs because of a 3D layered porous structure and good electronic conductivity. 117 The synthesized Ni−Co MOF/EGP showed a high area specific capacitance of 2.41 F cm −2 and a good rate performance of 72.6% at the current density range of 0.5−20 mA cm −2 . The excellent electrochemical energy storage performance of Ni−Co MOF/EGP benefits from the 3D layered porous structure and the good electrical conductivity of EGP and the layered structure of the integrated MOF-based electrode.…”

A Dually Charged Membrane for Seawater Utilization: Combining Marine Pollution Remediation and Desalination by Simultaneous Removal of Polluted Dispersed Oil, Surfactants, and Ions

“…In addition, when encountering complex wastewater that may contain highly viscous oil, micromolecules, and ions, liquid selectivity of common nanofiltration-dominated membranes is inferior. Specifically, the efficient removal of ions and micromolecules is carried out under high pressure generally, which may destroy the Laplace pressure of oil droplets on a hydrophilic surface. − Moreover, membranes without interfacial and structural modification may be easily contaminated and incapacitated by oil with high viscosity. − Therefore, how to design a material to overcome the above defects and achieve the breakthrough from a single target to multiple targets is still elusive.…”
