Present research is giving attention to fabricate heterojunction nanocomposite structures. In this current study, Ce³⁺-doped TiO₂@MoS₂ nanocomposites were prepared by hydrothermal synthetic route. Structural and morphological studies of Ce³⁺-doped TiO₂@MoS₂ nanocomposites were examined by various characterization techniques. PXRD results revealed that Ce³⁺ ions were successfully doped into TiO₂ and concurrently attached with MoS₂ to get heterojunction nanostructures. The effect of MoS₂ and Ce³⁺ ions on TiO₂ host matrix for the photocatalytic degradation of direct green (DG) dye was evaluated and the photocatalytic performances of Ce³⁺:TiO₂@MoS₂ nanocomposite confirm that it is two times greater than that of MoS₂ and Ce³⁺:TiO₂. Also, the prepared nanocomposite was utilized for cyclic voltammetry studies and found good electrochemical behaviour for battery and super capacitors. This research work presents a highly efficient nanocomposite to decompose the organic dyes that support to design the new structure for environmental pollution remediation and good electrode for super capacitor and battery applications.
