Abstract

A 2D few-layer black phosphorus/NiCo MOF (BP/NiCo MOF) hybrid is rationally designed and directly utilized as a lithium-ion battery anode.

Significantly Enhanced Ultrathin NiCo-based MOF Nanosheet Electrodes Hybrided with Ti3C2Tx MXene for High Performance Asymmetric Supercapacitors

“…NiCo-MOF exhibits the similar XRD pattern with Co-MOF (JCPDS 985792, C2/m). 51 Here, Co and Ni ions are octahedrally coordinated to hydroxyls, and these pseudo octahedrals are connected to form layered structure. The layers are bridged by the terephthalate groups to form the threedimensional layered structure.…”

Progress and Perspective of Metal‐ and Covalent‐Organic Frameworks and their Derivatives for Lithium‐Ion Batteries

“…Compared with the pristine MOF and POM, this material's electrochemical performance is almost the best, opening a new way for a branch of electrode materials for LIBs. Additionally, Zhou et al [67] . have reported 2D BP/NiCo MOF using Ni 2+ , Co 2+ and benzene dicarboxylic acid (BDC) as precursor via a facile solution reaction route at room temperature.…”

“…Although it is not a perfect electrode for LIBs, this pioneering work provides researchers a new choice to explore MOF materials for LIBs. Recently, several other MOFs are studied, including Si/Ni 3 (HITP) 2 , [66] BP/NiCo MOF, [67] Cu-CAT, [68] UiO-67, [69] NNU-11, [70] POMOFs/RGO, [71] NENU-507, [72] HP-NENU-5/CC, [73] and Ni-BHC. [74] For example, Lan et al [71] has synthesized polyoxometalates based MOFs (PO-MOFs)/RGO by combining the advantages of the POMs, MOFs and RGO, such as POM's multi-electron redox characteristics, RGO's high electronic conductivity and MOF's open frame on buffering the volume expansion and improving cycling stabilities.…”
