“…Their performances are not reliable due to slow kinetics and instability in alkaline media. So, scientists are trying to identify earth‐based electrocatalysts that are both low‐cost and non‐precious and that can permit OER while also supplying high yields and solidity in the long run 19 . Oxides and hydroxides of transition metals (TM) have been examined and worked on extensively over the past decade to reduce the OP of OER 20 .…”

Electrocatalytic water splitting is an essential hydrogen production method for resolving present energy shortage and progress toward more efficient technologies. For this purpose, a versatile and cheap electrocatalysts are the main challenge along the way. In this report, we synthesized vanadium telluride and carbon nanotube (VTe–CNT)‐based nanocomposite via facile hydrothermal route. The VTe–CNTs are characterized by X‐ray diffraction analysis, scanning electron microscopy, energy‐dispersive spectroscopy, Fourier transform infrared spectroscopy, and Brunauer–Emmett–Teller. These characterizations depict nanosphere structures, morphology, and high surface area that maintains high porosity, which are essential for inclusive water‐splitting phenomena in 1.0 M solution of KOH. Additionally, the electrochemical performance of VTe–CNTs has shown best O2 evolution reactions activity with of onset potential of 1.42 V versus reversible hydrogen electrode and required 10 mA/cm2 of current density at 278 mV overpotential, which is excellent among other electrocatalysts, VTe (342 mV@10 mA/cm−2) and CNTs (365 mV@10mA/cm−2). Moreover, VTe–CNT exhibits remarkable stability for almost 20 h. It also requires a low onset potential of 0.05 V with a small Tafel slope of 47 mV/dec for H2 evolution reactions. Hence, this research might facilitate the easy transportation of electrons and open up the new era, serving as an excellent replacement for noble metal–derived materials.

“…Effect of Ag 0.006 Te, Ag 0.012 Te, Ag 0.025 Te, Ag 0.05 Te, and Ag 0.1 Te nanostructure was determined with crystallite size found in the range of 85 nm, 73 nm and 39 nm, and 67 nm and 88 nm, respectively, measured with Debye Scherer 6. The Ag 0.025 Te substance has a smaller crystallite size of 39 nm that is responsible for the higher surface area, providing more active sites for adsorption of OH ions from electrolyte, which is beneficial for supercapacitor applications. , bold-italicD = bold-italicK bold-italicλ .25em bold-italicβ .25em nobreak0em0.25em⁢ boldcos nobreak0em.25em⁡ bold-italicθ …”

“…There has been a lot of focus in recent years on developing renewable clean energy sources owing to the depletion of fossil fuels, and their burning also creates environmental pollution as well global warming. − The growing need for new forms of energy storage along with conversion has been driven because of fast consumption regarding non-renewable and non-availability of renewable sources. As a result of the intermittent nature of sustainable energy supplies, building new forms of large-scale energy storage devices has become an incredibly difficult research problem. − Additionally, the development of devices that can withstand tens of thousands of charge/discharge cycles without deteriorating in performance or capacity is required due to the extensive worldwide demand. Supercapacitors gained a piqued interest because of the outstanding as well as higher power capacitive behavior.…”

A massive amount of power is required to meet the worldwide need for gratifying human aspirations. As a result, the possible effect on the energy storage equipment is crucial to ensure a steady supply of energy. However, a supercapacitor is a potential device that provides a sustainable source of energy. In the current work, we presented a fabrication of Ag 2 Te at different concentrations of 0.006, 0.012, 0.025, 0.05, and 0.1 M via a hydrothermal approach for energy storage devices. A variety of analytical techniques were employed to assess its structure, morphology, and textural property regarding the fabricated electrode. Among different electrode materials, the Ag 0.025 Te electrode exhibited the large C s of 711.86 F g −1 , E d of 35.12 W h Kg −1 , and P d of 298.4 W Kg −1 at a current density of 1 A g −1 . The stability test of Ag 0.025 Te shows 92.96% retention of capacitance over 5000 GCD cycles with little destruction in the structure as determined by XRD. EIS responses indicated that the improved performance in 1.0 M KOH is because of low hydration sphere radius, strong ionic conductivity of K + , and less electrode resistance. The encouraging results suggest that the Ag 0.025 Te nanorod might provide an ideal cathode material for supercapacitor applications.

“…Electrolysis can occur at a thermodynamic potential as low as 1.23 V 6,7 . However, because they are endothermic, as well as due to heterojunction resistance and series resistance ( R s ), the process of electrolysis is hindered, and a significant input potential, also referred to as an overpotential, is required 8,9 . Finding methods that improve this system's electrochemical viability at low overpotential is therefore crucial.…”

For practical H2 generation, it is currently difficult to create modules for electrochemical water splitting that are efficient and inexpensive over a broad pH range. In this study, a novel ZnC8@NCNT electrocatalyst is fabricated via simple pyrolysis of melamine with zinc chloride and carbon nanotubes (CNTs). The self‐assembled hybrid material was examined to catalyze the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in an alkaline pH range, and the ZnC8@NCNT responds with a lower OER overpotential of 245 mV, and smaller Tafel slope of 50.0 mV dec−1 with the turnover frequency (TOF) of 0.67 s−1 due to its unique structure. The HER response of the generated material is quite satisfactory with an overpotential of 223 mV and a Tafel value of 107 mV dec−1. The fabricated material supported by conductive CNTs increases the catalytic reactivity due to the synergistic manner, which is superior in performance as a cutting‐edge catalyst for water electrolysis in an electrolytic cell. Furthermore, ZnC8@NCNT establishes as a cost‐effective alternative to expensive Ir, Pt, Pd, and Ru‐based catalysts.
