Robust 2D/0D/2D MXene@TiO2/ZnIn2S4 ternary integrated heterojunction with efficient multi-interface charge transport and enhanced surface adsorption for gas sensing

Key Points

• Gas sensing performance improved significantly with the incorporation of MXene@TiO2/ZnIn2S4 heterojunction.
• Charge transport efficiency was notably enhanced, facilitating faster response times for gas detection.
• The study employed a multi-interface analysis to explore the interactions between materials in the heterojunction.
• Implications indicate that this heterojunction design could lead to more sensitive and efficient environmental sensors.
