Abstract A distinguishing feature of MAX phases and their MXene derivatives is remarkable chemical diversity. This diversity, coupled with the 2D nature MXenes, positions them as outstanding candidates for a wide range electrochemical applications. Chemical disorder introduced by solid solution can improve behavior. Up to now, adding considerable amount tungsten (W) in phase MXenes solutions, which enhance performance, proved challenging. In this study, synthesis M site Ti 1‐x W x are reported. The 211‐type (Ti ) 2 AlC exhibits disordered solution, whereas 312‐type 3 displays near‐ordered structure, resembling o ‐MAX, atoms preferentially occupying outer planes. Solid‐solution 2.4 0.6 C T z , 1.6 0.4 CT synthesized via selective etching high‐purity powder precursors containing 20% W. These evaluated sodium‐ion battery anodes, showing exceptional capacity, outperforming existing multilayer chemistries. work not only demonstrates successful integration meaningful quantities into double transition metal phase, but also paves way development cost‐effective Such advancements significantly widen application spectrum fine‐tuning physical, electronic, mechanical, electrochemical, catalytic properties.

Heliyon, Год журнала: 2024, Номер 11(1), С. e41261 - e41261

Опубликована: Дек. 18, 2024

Electrochemical energy storage plays a critical role in the transition to clean energy. With growing demand for efficient and sustainable solutions, supercapacitors have gained significant attention due their high specific capacitance, rapid charge/discharge capabilities, long lifespan, safe operation across various temperatures, minimal maintenance needs. This study introduces novel approach synthesis of high-performance supercapacitor electrodes by using MnNi-MOF-74 as precursor. Bimetallic Mn(OH)₂/Ni(OH)₂ hydroxides (MnNi-x, where x = 2, 6, 12) with tailored morphologies were successfully fabricated treating anchored on nickel foam different concentrations KOH. Among synthesized samples, MnNi-6 exhibited best performance, remarkable capacitance 4031.51 mF cm⁻2 at 2 mA cm⁻2, attributed its surface area 186 m2/g, optimized particle size, abundant micropores. Furthermore, demonstrated exceptional thermal stability, positioning it promising candidate high-temperature supercapacitors. It also excellent cycling retaining 86.34 % capacity after 10,000 cycles 10 highlighting durability. Density functional theory (DFT) calculations conducted explore quantum bimetallic hydroxide. The DFT results revealed electron density near Fermi level, which directly contributes Mn:Ni molar ratio 3:1. work underscores potential MOF-derived materials route development electrodes, paving way future advances electrochemical technologies.
