TiOnanorod arrays/TiCTMXene nanosheet composites with efficient photocatalytic activity.

Semiconductor photocatalysis holds significant promise in addressing both environmental and energy challenges. However, a major hurdle in photocatalytic processes remains the efficient separation of photoinduced charge carriers. In this study, TiOnanorod arrays were employed by glancing angle deposition technique, onto which TiCTMXene was deposited through a spin-coating process. This hybrid approach aims to amplify the photocatalytic efficacy of TiOnanorod arrays. Through photocurrent efficiency characterization testing, an optimal loading of TiO/TiCTcomposites is identified. Remarkably, this composite exhibits a 40% increase in photocurrent density in comparison to pristine TiO. This enhancement is attributed to the exceptional electrical conductivity and expansive specific surface area inherent to TiCTMXene. These attributes facilitate swift transport of photoinduced electrons, consequently refining the separation and migration of electron-hole pairs. The synergistic TiO/TiCTcomposite showcases its potential across various domains including photoelectrochemical water splitting and diverse photocatalytic devices. As such, this composite material stands as a novel and promising entity for advancing photocatalytic applications. This study can offer an innovative approach for designing simple and efficient photocatalytic materials composed of MXene co-catalysts and TiOfor efficient water electrolysis on semiconductors.
