Abstract:
MXenes are two-dimensional (2D) transition metal-based carbides, nitrides, and carbonitrides that are synthesized from its precursor MAX phase. The selective etching of the \"A\" from the MAX phase yields multi-functional MXenes that hold promise in a wide range of energy-based applications and biomedical applications. Based on its intended application, MXenes are prepared as multilayered sheets, monolayer flakes, and quantum dots. Conventionally, MXenes are prepared using hydrofluoric (HF) acid etching; however, the use of HF impedes its effective use in biomedical applications. This calls for the use of nontoxic HF-free synthesis protocols to prepare MXenes safe for biological use. Therefore, we have discussed a facile process to synthesize biocompatible, HF-free MXene nanosheets and quantum dots.
摘要:
MXenes是二维(2D)过渡金属基碳化物,氮化物,和由其前体MAX相合成的碳氮化物。从MAX相选择性蚀刻“A”产生多功能MXenes,在广泛的基于能源的应用和生物医学应用中具有希望。根据其预期应用,MXenes被制备为多层片材,单层薄片,和量子点。传统上,MXenes是使用氢氟酸(HF)酸蚀刻制备的;但是,HF的使用阻碍了其在生物医学应用中的有效使用。这要求使用无毒的无HF合成方案来制备对生物使用安全的MXenes。因此,我们已经讨论了合成生物相容性的过程,无HF的MXene纳米片和量子点。
