Assessing recent progress in MXene-based nanomaterials for oxygen evolution reactions.

As a new 2D material, MXenes are anticipated to impact future energy storage and conversion technologies significantly. This article reviews recent progress in MXene-based nanomaterials for oxygen evolution reaction (OER). In addition, the method of synthesizing these materials as an OER and essential concepts to motivate future research were highlighted, and obstacles to the sustainable development of this field were presented. A-layer selective etching with aqueous solutions containing fluoride ions is now the preferred method for developing MXenes. Until now, the difficulty in synthesizing a wide variety of MXenes has been attributed to Al high reactivity with fluoride-based aqueous media, which is particularly potent for those produced from MAX-phase precursors of containing Al. • Recent progress in MXene-based nanomaterials for oxygen evolution reaction is assessed. • Method of synthesizing these materials as an OER and essential concepts were highlighted. • Obstacles to the sustainable development of this field were presented.
