Here, we demonstrate gas-phase, thermally-driven selective oxidative tuning of structure and morphology of bulk Ti 3 AlC 2 (MAX phase) to yield (a) randomly oriented polycrystalline Ti 0.2 Al 1.8 C 4 O 5 nanowires (TACO NW) or (b) oriented single crystalline Ti 0.2 Al 1.7 C 5 O 5.3 nanorods (TACO NR). Hence, due to the advantages of heterogeneous nanostructure and defect activation, the FeCoNiPB/(FeCoNi)3O4-x nanoparticle modified HEA ribbon has a high catalytic activity for oxygen evolution reaction, which need low overpotentials of 229 mV and 406 mV to export 10 and 100 mA cm⁻² current density with a good stability.Įarth-abundant electrocatalysts for stable hydrogen generation in acidic conditions at low overpotential are highly desirable and yet extremely challenging due to the corrosive degradation of the catalysts at low pH (≤ 2). Besides, the (FeCoNi)3O4-x crystal that derived from amorphous HEA has rich defect structure, including lattice distortions, vacancy defects and discontinuous crystalline fringes. It is found that the obtained composite nanoparticles deposited on the surface of FeCoNiPB HEA ribbon with 3D porous array. In this work, amorphous FeCoNiPB high-entropy alloy (HEA) ribbons are prepared first, whose superficial species are conversed to FeCoNiPB/(FeCoNi)3O4-x composite nanoparticles with a diameter of ∼15 nm by the air after acid etching treatment. Meanwhile, design of nanostructure and fine-tuning of crystal structure could further improve their properties. The high-entropy materials have attracted rising attention for electrolysis application, which may have unusual performances due to the proximal configuration of dissimilar atoms. Grown CZTS crystals are thoroughly discussed. The single crystals growth and varied characterization results on the

The single crystals of Cu2ZnSnS4 (CZTS) are grown by direct vapor transport tech. However, their rapid deactivation at high temperatures still needs the attention of the scientific community. This review concluded that among all catalysts, nickel, ruthenium and platinum-based catalysts show the highest activity and catalytic efficiency and gave carbon-free hydrogen products during the TMD process. Finally, we presented the challenges and future perspectives for hydrogen production via TMD. A detailed overview of the different types of catalysts available, the reasons behind their deactivation, and their possible regeneration methods were discussed. Methods including steam methane reforming, partial oxidation of methane, auto thermal reforming, direct biomass gasification, thermal water splitting, methane pyrolysis, aqueous reforming, and coal gasification have been reported in this article. Various methods of hydrogen production from fossil fuels and renewable resources were discussed. The thermodynamics of this approach has been highlighted. This review article is focused on hydrogen production through thermocatalytic methane decomposition (TMD) for hydrogen production. Decomposition of methane yields hydrogen devoid of CO x components, thereby aiding as an eco-friendly approach towards large-scale hydrogen production. Hydrogen is an exciting energy source that can serve our energy purposes and decrease toxic waste production. Consumption of fossil fuels, especially in transport and energy-dependent sectors, has led to large greenhouse gas production.
