Functionalized Cu‐MOF@CNT Hybrid: Synthesis, Crystal Structure and Applicability in Supercapacitors

Abstract

The synthesis of am etal-organic framework (MOF) named IITI-1 is reported by employing an H 2 L linker with Cu(NO 3 ) 2 ·3 H 2 Oi namixed solvents ystem of N,N-dimethyl formamide (DMF) and H 2 O. Further,i no rder to explore the energy storagea pplication of IITI-1,aIITI-1/CNT hybrid wasp repared by as imple ultrasonication technique.I ncorporationo facarbon nanotube (CNT) in the layered IITI-1 MOF gave rise to enhanced electrolyte accessibility along with improved electrochemical storage capacity.T he electrochemical investigations revealahigh specific capacitance (380 Fg À1 at 1.6 Ag À1 )w ith ag ood rate performance for IITI-1/CNT.T he IITI-1 MOF and the IITI-1/CNT composite were characterized by PXRD, BET, SEM, and TEM techniques. Moreover, IITI-1 MOF was also confirmed by single-crystal XRD analysis.[a] S.

Advances on Emerging Materials for Flexible Supercapacitors: Current Trends and Beyond

“…To overcome this, scientists have collated CNT hybrid systems, by converting the CNTs to a conducting linker by Suzuki reactions. [ 60 ] It is obvious that the CNT in the form of linkers would be a better opponent to get hybridized with metal oxide layers, MOFs, graphene, etc., to exceptionally improve the diffusion kinetics. Similarly, an exciting work on embedding CNTs with hybrid perovskites carried out by Li et al., [ 61 ] increased the charge mobility and the current density.…”

Thermal Decomposition of [AH][M(HCOO)3] Perovskite-Like Formates

“…Beyond the thermal stability, understanding the decomposition process of coordination polymers opens new opportunities for their use as self-template precursors of highly stable metal or metal oxide materials [7][8][9][10][11] with potential applications in catalysis [12], energy storage and conversion [13], supercapacitors [14], batteries, and fuel cells [15].…”

Progress in supercapacitors: roles of two dimensional nanotubular materials

“…412 Some of the recent developments in high-performance supercapacitors using nanotubular networks have opened a new avenue for exploring techniques, specically electrode characterization and modulations, to achieve high power density, capacity retention, and good cyclability. 215,216,[223][224][225][226][227]264,386, Although the advancements and implementations of nanotubular networks in supercapacitors have signicantly achieved better storage capabilities and performance, tailoring and optimization of materials are still in a developmental phase where cost-effectiveness and good performance are some of the key concerns in practical applicability. In an attempt to develop a combination of high power and energy densities, hybrid technology is one of the challenging aspects.…”
