Metal organic framework derived CoNiOOH nanorods anchored on carbon cloth as electrodes for asymmetric supercapacitors

Stepwise Construction of MoS2@CoAl-LDH/NF 3D Core–Shell Nanoarrays with High Hole Mobility for High-Performance Asymmetric Supercapacitors

“…The peaks at 228.5 and 231.8 eV in Figure c can be ascribed to Mo 3d 3/2 and Mo 3d 5/2 , and the peak at 235.3 eV corresponds to the highly oxidized state of Mo 6+ owing to the oxidation of the material surface by air. , The distinct peak at 226 eV is associated with the S 2– originating from the S 2s orbital. , The S 2p spectroscopic analysis (Figure d) reveals three distinct signatures, corresponding to S 2p 3/2 (at 161.6 eV), S 2p 1/2 (at 162.6 eV), and SO x species (with a peak at 168.2 eV). , Figure e presents a spectroscopic analysis of Co 2p, featuring Co 2+ and Co 3+ at 781.2 and 778.8 eV for the Co 2p 3/2 state and 797.0 and 794.0 eV for the Co 2p 1/2 state. Additionally, two distinct signatures are observed at 803.2 and 786.4 eV, which can be ascribed to the satellite peaks associated with Co 2p . The spectrum of Al 2p depicted in Figure f exhibits two distinct peaks at 162.59 and 163.2 eV, corresponding to Al 2p 1/2 and Al 2p 3/2 respectively, representing their characteristic energies .…”

Metal–organic frameworks on versatile substrates

“…Carbon cloth (CC) is an ideal fiber substrate due to its light weight, good conductivity, and excellent thermal properties, which have been reported in these studies. 130–140 Among them, carbon fiber is a sort of one-dimensional material with exceptional strength and high conductivity, which is low-cost and light weight. 141 Yang's team has performed a lot of work on carbon fibers, such as developing an in situ assembly of MOF multi-level heterostructures on the surface of recycled carbon fiber.…”

In situ construction of core–shell structured cobalt oxide@nickel–cobalt-layered double hydroxide nanorods with abundant oxygen vacancies towards boosting electrochemical energy storage

“…9,10 Of the various electrode materials, transition metal-layered double hydroxides (LDHs), as a kind of 2D ionic platelike material, have garnered significant attention on account of their one-ofa-kind structures and remarkable theoretical capacity, thus making them a highly likely choice for SCs. 11,12 However, the future application of LDHs has been hindered by their insufficient electrical conductivity. Therefore, the promotion of intrinsic electron transport in materials exerts a profound influence on the structural design of electrode materials.…”
