Lithium–sulfur (Li–S) batteries exhibit unparalleled theoretical capacity and energy density than conventional lithium ion batteries, but they are hindered by the dissatisfactory "shuttle effect" sluggish conversion kinetics owing to low transport kinetics, resulting in rapid fading. Herein, a catalytic two-dimensional heterostructure composite is prepared evenly grafting mesoporous carbon on MXene nanosheet (denoted as OMC-g-MXene), serving interfacial kinetic accelerators Li–S batteries. In this design, grafted can not only prevent stack of nanosheets with enhanced mechanical property also offer facilitated pump for accelerating diffusion. Meanwhile, exposed defect-rich OMC-g-MXene inhibits polysulfide shuttling chemical interactions between polysulfides thus simultaneously enhances electrochemical efficiency, fully investigated situ/ex situ characterizations. Consequently, cells pumps achieve high cycling (966 mAh g–1 at 0.2 C after 200 cycles), superior rate performance (537 5 C), an ultralow decaying 0.047% per cycle 800 cycles 1 C. Even employed sulfur loading 7.08 mg cm–2 under lean electrolyte, ultrahigh areal 4.5 acquired, demonstrating future practical application.

Abstract Since the discovery in 2011, MXenes have become rising star field of two-dimensional materials. Benefiting from metallic-level conductivity, large and adjustable gallery spacing, low ion diffusion barrier, rich surface chemistry, superior mechanical strength, exhibit great application prospects energy storage conversion, sensors, optoelectronics, electromagnetic interference shielding biomedicine. Nevertheless, two issues seriously deteriorate further development MXenes. One is high experimental risk common preparation methods such as HF etching, other difficulty obtaining with controllable groups. Recently, Lewis acidic a brand-new strategy for MXenes, has attracted intensive attention due to its safety ability endow uniform terminations. However, comprehensive review etching method not been reported yet. Herein, we first introduce following four aspects: mechanism, terminations regulation, in-situ formed metals delamination multi-layered Further, applications MXene-based hybrids obtained by route sensors microwave absorption are carefully summarized. Finally, some challenges opportunities also presented.

MXene-based thermal camouflage materials have gained increasing attention due to their low emissivity, however, the poor anti-oxidation restricts potential applications under complex environments. Various modification methods and strategies, e.g., addition of antioxidant molecules fillers been developed overcome this, but realization long-term, reliable using MXene network (coating) with excellent comprehensive performance remains a great challenge. Here, hybrid comodified hyaluronic acid (HA) hyperbranched polysiloxane (HSi) is designed fabricated. Notably, presence appreciated HA oxidation sheets without altering infrared stealth performance, superior other water-soluble polymers; while HSi can act as efficient cross-linking agents generate strong interactions between molecules. The optimized MXene/HA/HSi composites exhibit mechanical flexibility (folded into crane structure), good water/solvent resistance, long-term stable capability (with emissivity ≈0.29). reliability (≈8 months) various outdoor weathers scalable coating MXene-coated textile enable them disguise IR signal targets in environments, indicating promise achieved material for camouflage, stealth, counter surveillance.
