Transition metal carbides/nitrides (MXenes) with eccentric properties are emerging 2D nanomaterials intriguing applications in the photo and electro-catalytic water splitting (Wsp). MXenes have a regular planer structure large specific surface area (SSA), excellent hydrophilicity, metallic conductivity, wide range of functionalities termination groups, making them promising candidate for long-term hydrogen generation (H2, gen). As result, their use as electro photo-catalysts Wsp to solve energy environmental challenges has increased. were proposed overcome major drawbacks TiO2, most commonly used photo-catalyst solar-driven Wsp, such high band gap fast recombination photo-induced charge carriers. MXene been rigorously investigated based on TiO2 modification (i.e. in-situ derived MXene-TiO2 MXene/TiO2 nanocomposite) well Metal-MXene co-catalyst that provides simple electron channelization improve overall photo-catalytic activity (CatA)toward increase evolution reaction (HER). However, several issues must be resolved before practical may considered, weak capabilities limited intrinsic catalytic activities. Although there few review papers synthesis, properties, Mxenes various fields, this present work focuses current advances synthetic MXene-derived nanohybrid composites Metals-MXene nanocomposite, clarifying carrier separation mechanism connection formed Schottky junction at MXene- elements interface attaining H2, gen. Furthermore, technical challenges, enhanced performance materials design derivative structural features presented. MXenes' is carefully outlined, along its photocatalytic electrocatalytic properties.

Hydrogen holds immense potential as a sustainable energy source result of its eco-friendliness and high density. Thus, hydrogen can solve the environmental challenges. However, it is crucial to produce using approaches in cost-efficient manner. Currently, be produced by utilizing diverse feedstocks, such natural gas, methane, ammonia, smaller organic molecules (methanol, ethanol, glycerol, formic acid), biomass, water. These feedstocks undergo conversion into through different catalytic processes, including steam reforming, pyrolysis, decomposition, gasification, electrolysis, photo-assisted methods (photoelectrochemical, photocatalysis, biophotolysis). Researchers have extensively explored various catalysts, metals, alloys, oxides, non-oxides, carbon-based materials, metal–organic frameworks, for these methods. The primary objectives been attain higher activity, selectivity, stability, cost effectiveness generation. efficacy processes significantly dependent upon performance emphasizing need further research development create more efficient catalysts. during production, gases like CO2, O2, CO, N2, etc. are alongside hydrogen. Separation techniques, pressure swing adsorption, metal hydride separation, membrane employed obtain high-purity Furthermore, techno-economic analysis indicates that production reforming gas/methane currently viable commercially successful. Photovoltaic electrolysis has commercialized, but still higher. Meanwhile, other phase hold future commercialization.

Hydrogen, a sustainable energy source, has potential to address climate change. However, traditional steam reforming processes produce CO2. Alternative fuels like bio-alcohols, biogas, and LPG are being adopted for processes. This study presents thermodynamic comparative examination of employing different fuels, including methane, methanol, ethanol, propane, glycerol, biogas. The analysis focuses on the hydrogen yield, environmental impact, requirements these comparison with experimental results. analyses were conducted using AspenPlus® software, minimizing Gibbs free under specified conditions (T = 25–1000 °C, n 1–10, P 1–40 bar). Among examined, methane exhibited highest yields, reaching maximum values 96.10 %, 95.86 95.26 % respectively at 600 1 bar, water-to-fuel ratio 10. Ethanol, propane achieved yields 89.66 86.55 84.03 700 °C same pressure ratio.
