“…• Ag/AgCl is 0.2412, and overpotential (ï) is calculated by subtracting the onset thermodynamic potential of 0 V for the water-splitting system using Equation ( 5) [46,47]. Furthermore, for the practical application of electrocatalysts, it is essential to thoroughly evaluate their durability and stability towards the HER [51].…”

The development of transition metal (TM) catalysts to replace precious metals has garnered increasing interest. Specifically, platinum (Pt)-based catalysts have been extensively investigated for their electrochemical performance in hydrogen evolution reaction (HER), which offer a clean means of producing hydrogen fuel without carbon emissions. However, the reliance on Pt-based catalysts has hindered the progress of HER development. Therefore, researchers have explored metal-organic frameworks (MOFs) as a substitute for noble Pt-based catalysts to address this issue. Nevertheless, the low electroconductivity of pure MOFs restricts their application in electrochemical fields. To overcome this limitation, MXenes have emerged as a promising two-dimensional (2D) material for coupling with MOFs to create an electrocatalyst with high electrical conductivity, a large surface area, and a tunable structure. In this study, we report the synthesis of a Ti3C2Tx (MXene) nanosheet-encapsulated MOFs catalyst (Ti3C2Tx@ZIF-8) with high activity and a low cost by encapsulating the precursor with ZIF-8 for HER in alkaline media. The catalyst exhibits an overpotential of only 507 mV at 20 mA/cm2 and a low Tafel slope value of 77 mV/dec. Additionally, cyclic voltammetry (CV) indicates an electrochemical active surface area (ECSA) of 122.5 cm2, and chronopotentiometry demonstrates the stable nature of the catalyst over 20 h without any significant changes in the overpotential value. The excellent electrochemical properties of Ti3C2Tx@ZIF-8 suggest its potential as a promising material for energy conversion applications.

“…To date, noble metals have traditionally been employed as benchmark HER and OER catalysts because of exceptional catalytic efficacy and lower Tafel slope values. , However, due to their rarity and high price, these noble metal-based electrocatalysts are not applicable for broad-scope utilization. , Therefore, scientific attention has been sparked by substituting inexpensive, high-activity electrocatalysts alternative to noble metal catalysts. Because of their electrochemical solid activity, affordable price, and outstanding durability, transition metal-based (TMs) catalysts have attracted plenty of interest in electrochemistry. − It is crucial to build a reliable bifunctional electrocatalyst using readily available elements like nickel (Ni), iron (Fe), cobalt (Co), and copper (Cu) because of their affordability, dependability, and availability on land. − Ni and Fe are mainly regarded as species actively involved in the water-spitting process. Adding Ni and Fe metals with other metals might change the composite’s electronic state and considerably increase the electrochemical performance …”

Developing sustainable energy solutions to safeguard the environment is a critical ongoing demand. Electrochemical water splitting (EWS) is a green approach to create effective and long-lasting electrocatalysts for the water oxidation process. Metal organic frameworks (MOFs) have become commonly utilized materials in recent years because of their distinguishing pore architectures, metal nodes easy accessibility, large specific surface areas, shape, and adaptable function. This review outlines the most significant developments in current work on developing improved MOFs for enhancing EWS. The benefits and drawbacks of MOFs are first discussed in this review. Then, some cutting-edge methods for successfully modifying MOFs are also highlighted. Recent progress on nickel (Ni) and iron (Fe) based MOFs have been critically discussed. Finally, a comprehensive analysis of the existing challenges and prospects for Ni-and Fe-based MOFs are summarized.

“…Electrochemical water splitting is a green and cost-effective technology for producing hydrogen to meet energy needs for sustainable and environmentally friendly futures. [4][5][6] The electrochemical water splitting process requires electric power, which is generated via solar panels or wind generators, which are considered sustainable technologies. Water splitting involves two half-cell reactions, one of which is the hydrogen evolution reaction (HER) and the other is the oxygen evolution reaction (OER).…”
