| Abstract Scope |
Ti₃C₂Tₓ MXene holds promise for optoelectronic devices due to its conductivity and layered structure. However, its metallic nature limits photodetection efficiency. Partial oxidation to form TiO₂—a semiconductor known for its high surface area and strong light absorption—can address this limitation by introducing photoactive characteristics while retaining conductive pathways.
This work explores thermal treatment of Ti₃C₂Tₓ MXene to induce oxidation on the Ti sites. The goal is to convert surface layers into TiO₂ while preserving the MXene core, forming a hybrid structure capable of both light harvesting and rapid charge transport. Such a structure could enhance responsivity and response time by combining the optical sensitivity of TiO₂ with the electrical conductivity of MXene.
Through this approach, the study investigates how thermal processing parameters of MXene–TiO₂ composites can lead to tunable optoelectronic behavior for photosensing technologies. |
