Abstract:Galvanic replacement in molten salts has recently been uncovered as a pathway to design new compositions of layered transition-metal carbides related to the family of MAX phases, M n+1 AlX n , where M is a transition metal, X is carbon for carbide phases, and A is mainly an element of the IIIA and IVA groups of the periodic table. These compounds can be further involved in etching processes by the removal of A elements to yield new 2D transition-metal carbides, M n+1 X n T z , the so-called MXenes, where T sta… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
