Abstract. In this work, we have fabricated MoO3/MWCNT/g-C3N5 as formed 0D/1D/2D nanohybrid were synthesized using eco-friendly hydrothermal synthesis method for dye sensitized solar cell (DSSC) and supercapacitor. The phase structures, functional groups and optical features of synthesized samples were confirmed by different characterization analytical techniques. The self-assembled MoO3 nanoparticle and MWCNT were decorated on the g-C3N5 nanosheet surface and morphologies formed as 0D/1D/2D multi-dimensional nanostructures as confirmed from FE-SEM and HR-TEM analysis. The prepared materials used as counter electrodes for DSSC and the fabricated DSSC performance of the Jsc, Voc, FF%, and power conversion efficiency (PCE%) were 18 mA cm-2, 0.6 V, 0.70% and 7.58%, respectively. The electrochemical performance of MoO3/MWCNT/g-C3N5 electrodes in 1 M Na2SO4 showed a specific capacitance of 831 F/g at 1 A/g. Moreover, MoO3/MWCNT/g-C3N5 shown exceptional PCE % in the reduction of triiodide (I⁻/I₃⁻) and enhanced specific capacitance due to synergistic effects at the multifunctional interfaces of 0D-MoO3, 1D-MWCNT and 2D-g-C3N5. This study positively encourages simple self-assembly of 0D/1D/2D ternary hybrid synthesis and rational design of highly efficient DSSC solar cells and supercapacitors offer low-cost, safe, and reliable energy storage devices in the near future.
