Binary Ni–Cu nanocomposite-modified MXene-adorned 3D-nickel foam for effective overall water splitting and supercapacitor applications

“…[1][2][3] However, due to the rapidly increasing population together with the over consumption of energy, the increasing energy needs of society cannot be met by renewable energy sources such as wind power and geothermal and solar energy sources. 4 Accordingly, electric energy from energy conversion and storage devices such as lithium-ion batteries, 5,6 metal air batteries, 7,8 supercapacitors, [9][10][11][12][13] fuel cells 14,15 and electrochemical water splitting is becoming a more signicant part of modern life due to its efficiency, sustainability, and greenness. [16][17][18][19][20][21][22] Owing to its ability to produce pure green hydrogen with high energy density as fuel together with zero carbon emission, electrochemical water splitting is considered a promising alternative.…”

Self-supported 3D coral-like copper/poly diphenylamine on nickel foam: multifunctional exploration of overall electrochemical water splitting, alcohol oxidation reaction and supercapacitor applications

“…Due to their low operating temperature and relatively high productivity, direct alcoholic fuel cells (DAFCs), direct methanol fuel cells (DMFCs), and direct ethanol fuel cells (DEFCs) are taken into consideration. [23][24][25][26] Supercapacitors play a unique role in the field of energy storage because of the inexpensive electrode materials and the broad spectrum of industries in which they are used. Pseudocapacitance, electrical double-layered capacitance (EDLC), and battery-like behaviour are all examples of electroactive materials' charge storage mechanisms.…”

Layer-by-Layer Assembly of CTAB-rGO-Modified MXene Hybrid Films as Multifunctional Electrodes for Hydrogen Evolution and Oxygen Evolution Reactions, Supercapacitors, and DMFC Applications

“…Among the promising candidates of green energy storage devices, supercapacitors are widely adopted due to their rapid charge–discharge abilities, higher power density, and long cyclic stability, which would, for any practical application, allow electronic devices to be continuously used for an extended period and to be fully charged in a short duration. − However, developing an electrode material that is fast charging–slow discharging with an excellent performance rate is still challenging. When it comes to the need of green fuel for energy conversion, the usage of renewable energy sources like hydrogen is also thought to hold great promise for resolving the environmental problems, and one of the most cleanest methods of energy conversion currently being used is hydrogen generation via HER, i.e., via water electrolysis converting electrical energy into hydrogen energy. − Besides the electrolysis of water for hydrogen fuel, due to better efficiency and low emission levels, DMFCs have also been acknowledged as promising energy sources for mobile electronics and automobiles. − Compared to the hydrogen fuel cells, DMFCs have a higher energy density and exhibit easier solubilization of raw materials. However, the commercialization of these fuel cells has been constrained by high manufacturing costs, slowly occurring oxidation reaction of methanol on the anode of the fuel cell, and the production of carbon dioxide during their oxidation. − Hydrogen, on the other hand, is a zero-emission greenhouse gas and is hence wholly green. , …”
