MULTILEVEL OPTIMIZATION OF Ti2AlC SYNTHESIS PROCESS USING PRECURSORS OF KAZAKHSTAN ORIGIN

2D materials of the MXene family have attracted significant interest due to their multifunctional applications. MXene materials are derived from corresponding MAX phases, which are synthesized using various high-temperature methods (ranging from 1100 to 1450 ℃). Ti 2 AlC is one of the representatives of MAX phases, from which the corresponding 2D material, Ti 2 C, is obtained. The most common applications of Ti 2 C include its use as an active electrode material for supercapacitors and as a matrix for hydrogen evolution reaction catalysts. In this work, we conduct a study on the synthesis of Ti 2 AlC material, with multi-level optimization of the process to achieve the highest yield of the final product by mass. Based on the results of the study, the optimal synthesis temperature and time were determined to be 1350 ℃ and 2 hours, respectively. One of the distinctive features of this work is the use of precursors of Kazakhstan origin and the scaling up of the process (from 1 to 100 g of product), which will enable the commercial synthesis of Ti 2 AlC material in the future. From the Ti 2 AlC synthesized under optimal conditions, Ti 2 C was successfully obtained and used as an electrode material for a supercapacitor, demonstrating electrochemical performance comparable to that of commercial Ti 2 C.
