Use of MXenes (Ti 3 C 2 T x ), which belongs to the family of two-dimensional transition metal nitrides and carbides by encompassing unique combination of metallic conductivity and hydrophilicity, is receiving tremendous attention, since its discovery as energy material in 2011. Owing to its precursor selective chemical etching, and unique intrinsic characteristics, the MXene surface properties are further classified into highly chemically active compound, which further produced different surface functional groups i. e., oxygen, fluorine or hydroxyl groups. However, the role of surface functional groups doesn't not only have a significant impact onto its electrochemical and hydrophilic characteristics (i. e., ion adsorption/diffusion), but also imparting a noteworthy effect onto its conductivity, work function, electronic structure and properties. Henceforth, such kind of inherent chemical nature, robust electrochemistry and high hydrophilicity ultimately increasing the MXene application as a most propitious material for [a] A

“…Nevertheless, the discovery of novel photocatalysts, that are standard, robust, incredibly efficient for pragmatic evaluation, and simple to synthesize, as well as exhibiting great visual photocatalytic stimulation, remains a difficult problem for the scientific world. The photocatalytic stimulation effect is separated into various phases [43,44] . A photocatalyst is a substance that absorbs light energy produced by sunshine or any additional artificial light supply.…”

A Targeted Review of Current Progress, Challenges and Future Perspective of g‐C₃N₄based Hybrid Photocatalyst Toward Multidimensional Applications

Anwar

et al. 2022

The increasing demand for searching highly efficient and robust technologies in the context of sustainable energy production totally rely onto the cost-effective energy efficient production technologies. Solar power technology in this regard will perceived to be extensively employed in a variety of ways in the future ahead, in terms of the combustion of petroleumbased pollutants, CO 2 reduction, heterogeneous photocatalysis, as well as the formation of unlimited and sustainable hydrogen gas production. Semiconductor-based photocatalysis is regarded as potentially sustainable solution in this context. g-C 3 N 4 is classified as non-metallic semiconductor to overcome this energy demand and enviromental challenges, because of its superior electronic configuration, which has a median band energy of around 2.7 eV, strong photocatalytic stability, and higher light performance. The photocatalytic performance of g-C 3 N 4 is perceived to be inadequate, owing to its small surface area along with high rate of charge [a] A

“…With the on-growing energy demand, swift exhaustion of fossil fuels, and worsening environmental pollution, acquiring additional renewable fuel alternatives, such as energy production, hydroelectricity, geothermal power, and biofuels is essential. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Owing to outstanding energy conversion proficiency, larger gravimetric energy output than petroleum (120 vs. 44 MJ/kg 1 ), absence of carbon dioxide (CO 2 ) emitters, and environmental adaptability hydrogen (H 2 ) is often regarded as the cleanest and most ideal energy source in order to replace fossil fuels.

Recent Advances and Future Perspectives of Metal‐Based Electrocatalysts for Overall Electrochemical Water Splitting

Ali

et al. 2022

Recently, the growing demand for a renewable and sustainable fuel alternative is contingent on fuel cell technologies. Even though it is regarded as an environmentally sustainable method of generating fuel for immediate concerns, it must be enhanced to make it extraordinarily affordable, and environmentally sustainable. Hydrogen (H2) synthesis by electrochemical water splitting (ECWS) is considered one of the foremost potential prospective methods for renewable energy output and H2 society implementation. Existing massive H2 output is mostly reliant on the steaming reformation of carbon fuels that yield CO2 together with H2 and is a finite resource. ECWS is a viable, efficient, and contamination‐free method for H2 evolution. Consequently, developing reliable and cost‐effective technology for ECWS was a top priority for scientists around the globe. Utilizing renewable technologies to decrease total fuel utilization is crucial for H2 evolution. Capturing and transforming the fuel from the ambient through various renewable solutions for water splitting (WS) could effectively reduce the need for additional electricity. ECWS is among the foremost potential prospective methods for renewable energy output and the achievement of a H2‐based economy. For the overall water splitting (OWS), several transition‐metal‐based polyfunctional metal catalysts for both cathode and anode have been synthesized. Furthermore, the essential to the widespread adoption of such technology is the development of reduced‐price, super functional electrocatalysts to substitute those, depending on metals. Many metal‐premised electrocatalysts for both the anode and cathode have been designed for the WS process. The attributes of H2 and oxygen (O2) dynamics interactions on the electrodes of water electrolysis cells and the fundamental techniques for evaluating the achievement of electrocatalysts are outlined in this paper. Special emphasis is paid to their fabrication, electrocatalytic performance, durability, and measures for enhancing their efficiency. In addition, prospective ideas on metal‐based WS electrocatalysts based on existing problems are presented. It is anticipated that this review will offer a straight direction toward the engineering and construction of novel polyfunctional electrocatalysts encompassing superior efficiency in a suitable WS technique.
