ABSTRACT

The Ti3C2Tx MXene is an emerging material for electrical devices, sensing, energy, environmental, and biomedical applications. Therefore, the effective development of synthesis and functionalization strategy has been triggered from delamination via etching routes to the addition of functional groups. The present report demonstrates the synthesis of Ti3C2Tx and modification by titanium dioxide (TiO2). The incorporation of titanium dioxide (TiO2) showed different morphology, chemical structures, and chemical composition compared to Ti3C2Tx. Moreover, the electrical characteristics have been investigated and showed a promising performance as semiconductor devices. The existence of titanium dioxide turned the Ti3C2Tx IV characteristics from ohmic behavior toward the Schottky behavior, resulting in enhanced hysteresis of memory devices and responsibility of chemical sensors upon NO2 gas.
