Conductive NiMn-based bimetallic metal–organic gel nanosheets for supercapacitors

Abstract

Recently, the easy processability and dynamic properties of metal-organic gels (MOGs) have highlighted their application in sensing, adsorption, catalysis. However, people rarely realize the potential application of metal organic gels...

Metal–organic gels and their derived materials for electrochemical applications

“…Bimetallic NiMn-BTC gels were developed by Zhong et al by simply mixing metal ions (Ni 2+ and Mn 2+ ) and H 3 BTC. 194 The bimetallic gel NiMn-3 MOG (the molar ratio of Ni/Mn is 3 : 1) possesses the morphology of laminated nanosheets. It has high conductivity of 1.12 S m −1 .…”

Bimetal Metal–Organic Framework-Derived Ni–Mn@Carbon/Reduced Graphene Oxide as a Cathode for an Asymmetric Supercapacitor with High Energy Density

“…Zhong et al studied the synergetic effect with different ratios of two metal ions. 33 Compared with single-metal MOFs, bimetal components tend to have minor particles, larger volume, and more metal active sites due to the introduction of heterogeneity. 34 However, in his research, bimetallic MOFs still face challenges such as the exposure of metals to the electrolyte, which can result in a low specific capacitance (∼692.9 F g −1 at 1 A g −1 ) and poor stability (84.54% capacity retention after 5000 cycles) of supercapacitors.…”

“…To further enhance the properties of MOF-derived materials for supercapacitor electrodes, researchers have explored the use of bimetallic MOFs. Zhong et al studied the synergetic effect with different ratios of two metal ions . Compared with single-metal MOFs, bimetal components tend to have minor particles, larger volume, and more metal active sites due to the introduction of heterogeneity .…”

A tris-tetrazole based nanostructured soft material: studies on self-healing, AIEE, and rheological and fluorometric detection of 3-aminopyridine

“…This phenomenon opens up the possibility to utilize LMWGs as sensing materials. [16][17][18] Interestingly, the position of the complementary donor-accepter sites of hydrogen bonds can play a crucial role in molecular recognition phenomena as evident in biological molecules like DNA. 19,20 There are only a few studies available where the properties of a gel have been utilized to discriminate between isomeric organic molecules.…”
