摘要

Two dimensional MXenes like Ti3C2Tx have been of interest due to their outstanding electrical and optical characteristics. Ti3C2Tx is a layered 2D carbide that is based on a lamellar structure and has a very high in-plane conductivity, in addition to a significant plasmonic optical response. ZnFe2O4 is a spinel ferrite semiconductor that is active in visible light and has good magnetic properties. In this article Ti3C2Tx MXene was prepared by HF etching of Ti3AlC2 MAX phase and ZnFe2O4 by solgel auto-combustion method. Both the constituents have been gone through solvothermal synthesis process to prepare Ti3C2Tx/ZnFe2O4 composites. XRD analysis verified the formation of the composite, in which the crystalline structures of both phases were maintained and the interfacial interaction was observed in terms of the crystallite size development (12 and 10 nm in the individual components to 15 and 12 nm in the composite). The band gap of MXene was fine-tuned by the addition of ZnFe2O4 followed by further enhancement thorough the annealing of the composite. The conductivity shot up for the higher energies of the photons (above 3.5 eV) and electrical measurements affirmed semiconducting behavior. Temperature-dependent magnetic features have been investigated from 300 to 5 K manifesting improved exchange bias (Hex) and coercivity (Hc) from 1.6 Oe to 35.4 Oe and 662.7 Oe to 752.7 Oe, respectively, emphasizing the potential implementation of Ti3C2Tx/ZnFe2O4 composites in optical and magnetic devices.
