Two-dimensional nanomaterial MXenes for efficient gas separation: a review

Abstract

Transition metal carbides/nitrides (MXenes) are an emerging two-dimensional (2D) material that has been widely investigated in recent years. The material can usually be obtained from MAX phase ceramics after intercalation,...

MXenes vs. clays: emerging and traditional 2D layered nanoarchitectonics

“…23 MXenes are receiving tremendous interest due to their exceptional physicochemical properties endowing advanced technological applications and constituting therefore marked progress in the field of new functional materials. [22][23][24][25][26][27] MXenes are also known by the nickname of "conductive clays", † apparently because of their similar characteristics to clay minerals. 28 The appellation of clays as MXenes would be attributed to their similarity in terms of physicochemical properties like those of some 2D clays.…”

“…23 MXenes are receiving tremendous interest due to their exceptional physicochemical properties endowing advanced technological applications and constituting therefore marked progress in the field of new functional materials. 22–27 MXenes are also known by the nickname of “conductive clays”,††See for instance the two most cited articles searching by “Clay* and Intercalation” as the topic entries in Clarivate-WoS, which are related to MXenes, both published in 2014 with a total of ca. 7000 citations.…”

Synthesis and up-to-date applications of 2D microporous g-C3N4 nanomaterials for sustainable development

“…Therefore, sustainability has attracted the interest of both academia and industry, and it is clear that it has become a key factor influencing both academic and industrial fields and is beginning to lead an increasing number of research areas such as polymers, batteries, photochemistry, biomass conversion, energy harvesting, etc. [1][2][3][4][5][6] To solve this problem, the most important thing is to start from various industrial sources to achieve energy saving and emission reduction or recycling. Therefore, it is necessary to find materials that not only have similar properties or possess higher performance, but also can be prepared through sustainable synthetic routes.…”

“…[17][18][19][20][21] Specifically, as shown in the Fig. 1, the main 2D materials are graphene, 22 graphene oxide (GO), 23 boron nitride (BNs), 24 metal organic frameworks (MOFs), 25 covalent organic frameworks (COFs), 26 transition metal carbides and nitrides (MXenes) 6 and g-C 3 N 4 , etc. 27 These materials are playing an increasingly important role in sustainable research.…”
