Bimetallic solid solution MAX phases, known for their tunable properties, have faced challenges with uneconomical synthesis methods involving high temperature, pressure, and inert atmospheres. To address this, our study introduces a cost-effective alternative—modified molten salt shielded synthesis, producing (TixV1-x)₂AlC MAX phases with varying Ti/V ratios. This meticulous work provides insights into the synthesis and behavior of the solid solution-based (TixV1-x)₂AlC MAX phase across thermal, optical, and electrical aspects.
Transitioning to the second part, we explore the purity and hydrogen storage by MAX phases. Highlighting the importance of multilayer and porosity in energy storage materials, we detail the formation of low-temperature, porous, and highly pure bimetallic solid solution Titanium Vanadium Aluminum Carbide (TiVAlxC) MAX phases in an open atmosphere. A groundbreaking aspect of this work is the introduction of gravimetric analysis for isothermal hydrogen adsorption, showcasing the hydrogen storage capabilities of pure TiVAlxC MAX phases and their end phases, paving the way for future applications in hydrogen storage.
