MAX phases are layered and have the general formula: Mn+1AXn, (MAX) where n = 1 to 3, M is an early transition metal, A is a non-metal element and X is either carbon and/or nitrogen. Whereas, MXenes are a class of layered materials made from the precursor MAXene by removing the A element. Thus, they are named MXenes. While the precursor has Mn+1AXn chemical formula MXene has M(n+1)Xn formula.
