Abstract:
The urgent issues related to the catalytic processes and energy applications have accelerated the development of hybrid and smart materials. MXenes are a new family of atomic layered nanostructured materials that require considerable research. Tailorable morphologies, strong electrical conductivity, great chemical stability, large surface-to-volume ratios, tunable structures, among others are some significant characteristics that make MXenes appropriate for various electrochemical reactions, including dry reforming of methane, hydrogen evolution reaction, methanol oxidation reaction, sulfur reduction reaction, Suzuki-Miyaura coupling reaction, water-gas shift reaction, and so forth. MXenes, on the other hand, have a fundamental drawback of agglomeration, as well as poor long-term recyclability and stability. One possibility for overcoming the restrictions is the fusion of nanosheets or nanoparticles with MXenes. Herein, the relevant literature on the synthesis, catalytic stability and reusability, and applications of several MXene-based nanocatalysts are deliberated including the merits and cons of the newer MXene-based catalysts.
摘要:
与催化过程和能源应用相关的紧迫问题加速了混合和智能材料的发展。MXenes是一类新的原子层状纳米结构材料,需要大量的研究。定制的形态,强导电性,良好的化学稳定性,大的表面体积比,可调结构,其中一些重要的特性使MXenes适用于各种电化学反应,包括甲烷的干重整,析氢反应,甲醇氧化反应,硫还原反应,Suzuki-Miyaura偶联反应,水煤气变换反应,等等。MXenes,另一方面,有团聚的根本缺点,以及较差的长期可回收性和稳定性。克服这些限制的一种可能性是纳米片或纳米颗粒与MXene的融合。在这里,关于合成的相关文献,催化稳定性和可重复使用性,讨论了几种基于MXene的纳米催化剂的应用,包括新型基于MXene的催化剂的优缺点。
