In this study, we successfully demonstrate the electrochemical etching of Al from porous Ti2AlC electrodes in dilute hydrochloric acid to form a layer of Ti2CTx MXene on Ti2AlC.
TiCT and other types of MXene nanosheets are an exciting new class of 2D materials. However, little has been reported on manipulating the shape of MXene nanosheets. Here, we demonstrate that flat TiCT nanosheets encapsulated within spray-dried droplets can be scrolled, bent, and folded into 3D crumpled structures. This morphological change was observed to be reversible upon rehydration.
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.
