Functionalization of metal oxides nanomaterial by different organic and inorganic species could considerably enhance the electrochemical performance of a supercapacitor. Here, we have synthesized and functionalized ZnO nanoparticles (NPs) via organic compounds of E. cognate and then doped the synthesized nanomaterials by NiO following hydrothermal route involving the bioactive compounds. As synthesized ZnO@NiO was analyzed by field emission-scanning electron microscopy at nanoscale. The organic functional groups were delineated by X-ray photoelectron spectroscopy as well as by Fourier transform infrared spectroscopy. What is more, Tauc plot revealed drastically decreased band gap energy of ZnO@NiO to 2.48 eV resulting in an enhanced electrochemical properties. Therefore, organic framework derived ZnO@NiO nanomaterial was scrutinized as an electrode for supercapacitor by galvanostatic charge-discharge, cyclicvoltammetry and electrochemical impedance spectroscopy. ZnO@NiO electrode demonstrated specific capacitance of 185 Fg −1 by cyclicvoltammetry, proposing its potential towards supercapacitor due to nanoscale particles and incorporated C, O, and N atoms of organic compounds.

“…And in previous studies, the carbon materials with electrochemical hydrogen storage have been applied to secondary cell, asymmetric supercapacitor and hydrogen ion supercapacitor. 30,[32][33][34][35][36] The properties and applications of the carbon materials depend largely on their surface structural characteristics. Hence, it is necessary to introduce heteroatoms on the surface of carbon materials for functional modification.…”

“…[20][21][22][23][24][25][26] Besides, the electrochemical hydrogen storage also possesses the merits of simplicity, reusability and safety. 27 The mechanism of electrochemical storage contains a few steps as described below: [13][14][15]24,[28][29][30][31] I. In the electrochemical reduction process (charging): when the electrons are transferred from the carbon electrode to the H 2 O molecules in the electrolyte at electrode/electrolyte interface, isolated H atoms are formed and adsorbed on the electrode surface (Volmer reaction).…”

Activated carbon materials doped with different nitrogen contents and nitrogen functional groups were synthesized. Nitrogen doping can improve the electrochemical hydrogen storage activity as well as the hydrophilicity of the carbon materials. Synthesized with the optimal synthesis conditions, the Ndoped activate carbon demonstrated the hydrogen storage capacity of 148.4 mAh g −1 under 100 mA g −1 rate, and 84.3% capacity retention at a high current density of 1000 mA g −1 . 73.4% hydrogen could be preserved after a 24 hours rest at open potential. The main nitrogen functional groups on this carbon material were found to be pyrrole N, pyridine N oxide and nitro N. The density functional theory (DFT) calculations revealed that the H adsorption energy on pyridine N and pyrrole N was larger than that of pyridine N, while graphite N had no advantage in improving the H adsorption energy of carbon materials.

Mg‐S batteries hold great promise as a potential alternative to Li‐based technologies. Their further development hinges on solving a few key challenges, including the lower capacity and poorer cycling performance when compared to Li counterparts. At the heart of the issues is the lack of knowledge on polysulfide chemical behaviors in the Mg‐S battery environment. In this Review, we provide a comprehensive overview of the current understanding of polysulfide behaviors in Mg‐S batteries. First, we provide a systematic summary of experimental and computational techniques for polysulfide characterization. Next, conversion pathways for Mg polysulfide species within the battery environment are discussed, highlighting the important role of polysulfide solubility in determining reaction kinetics and overall battery performance. The focus then shifts to negative effects of polysulfide shuttling on Mg‐S batteries. We outline various strategies for achieving an optimal balance between polysulfide solubility and shuttling, including use of electrolyte additives, polysulfide‐trapping materials, and dual‐functional catalysts. Based on the current understanding, we identify directions for further advancing knowledge of Mg polysulfide chemistry, emphasizing the integration of experiment with computation as a powerful approach to accelerate the development of Mg‐S battery technology.This article is protected by copyright.
