description The present paper scrutinizes the production and versatile application of Co2TiO4/CoTiO3 nanocomposites (NCs), especially their photocatalytic performance, which outperforms their superior supercapacitor storage. XRD and SEM methods were employed to study the crystalline structure and morphology of the Co2TiO4/CoTiO3 generated by the use of the Pechini process. SEM data show nanoparticles with a small amount of aggregation, emphasizing the impact of certain preparation condition, such as calcination temperature and molar ratio of precursors. The Co2TiO4/CoTiO3 nanocomposites prepared with 0.5:1 molar ratio of Co2+:Ti4+ at 850°C were then thoroughly examined for their potential to store energy as well as for photocatalytic activity. Our research focused on nanoparticle-based supercapacitors and essential nanoparticle properties including energy storage. The synthesized Co2TiO4/CoTiO3 displayed exceptional supercapacitor efficiency. These customized NCs exhibited improved energy storage capability and demonstrated a specific capacitance of 277.7 F g‒1. The power density reached 1201.5 W.kg−1, indicating that Co2TiO4/CoTiO3 NCs have a promising future in high-energy storage systems. Furthermore, cyclic stability tests were the key component that contributed significantly to advancing actual device applications. After 5000 cycles, Co2TiO4/CoTiO3 preserved 97.6% of its capacitance, demonstrating the stability of Co2TiO4/CoTiO3 and endurance for long-term energy storage. In contrast, Co2TiO4/CoTiO3 demonstrated high photocatalytic efficiency with several organic dyes, especially methylene blue (MB), which was 95% destroyed after 90 minutes of reaction time under visible light. The Co2TiO4/CoTiO3 impact primarily increased photocatalytic activity by facilitating charge separation and migration, which enhanced organic pollutant degradation. The results add to the expanding field of nanotechnologies and nanoscience, providing a promising avenue for creating sophisticated materials with multifunctional capability.
