Abstract The aim was to optimize energy production and minimize losses with regard sources of sustainable energy, particularly solar by examining a variety absorber designs developed from various materials. Metamaterial MXene/W-based Resonator Solar Absorber (MMRSA) using MXene Tungsten material utilized in resonator, which has tiny wire cylindrical ring-shaped geometry. MgF 2 as substrate used the ground layer suggested absorber. MMRSA worked at 200–3000 nm range gained more than 94% absorptance.

Few-Layered MXene Modulating In Situ Growth of Carbon Nanotubes for Enhanced Microwave Absorption

Molecules, Journal Year: 2025, Volume and Issue: 30(7), P. 1625 - 1625

Published: April 5, 2025

MXene is widely used in the fields of microwave absorption and electromagnetic shielding to balance pollution with development communication technologies human health, due its excellent surface functional groups tunable electronic properties. Although pure multilayered has an accordion-like structure, weak dielectric loss lack magnetic result poor performance. Here, we propose a strategy for catalytic growth CNTs by electrophoretic deposition adsorbed metal ions, leading successful preparation Ni-MWCNTs/Ti3C2Tx composites “layer-by-layer” achieved through situ regulated CNTs. By introducing dielectric–magnetic synergy improve impedance matching conditions, regulating diameter alter parameters Ni-MWCNTs/Ti3C2Tx, 2-Ni-MWCNTs/Ti3C2Tx composite achieves best reflection (RL) value −44.08 dB effective bandwidth 1.52 GHz at only 2.49 mm thickness. This unique layered structure regulation provide new opportunities few-layered composites.

Enhancing the Performance of MXenes and MBenes-Based Materials for Maximized Efficiency in the Oxygen Reduction Reaction

IGI Global eBooks, Journal Year: 2025, Volume and Issue: unknown, P. 171 - 202

Published: April 8, 2025

MXenes and MBenes, advanced two-dimensional materials with outstanding structural electronic properties, are gaining prominence in energy conversion storage, particularly for the oxygen reduction reaction (ORR). ORR, essential fuel cells metal-air batteries, suffers from sluggish kinetics, efficient catalysts. While noble metals like platinum excel this role, their high cost scarcity necessitate alternatives. MXenes, consisting of transition metal carbides, nitrides, or carbonitrides, exhibit metallic conductivity tunable surface chemistry, making them ideal ORR catalysis. Similarly, nitride-based analogs, show great promise. Optimization methods selective etching, functionalization, heteroatom doping significantly enhance catalytic performance. This review explores synthesis, structure, mechanisms highlighting recent progress, addressing stability scalability challenges, identifying future directions improving efficiency sustainable applications.
