In recent years, optically active functional nanocatalysts have attracted immense scientific research due to their robust application in photocatalytic H2 energy production, CO2 reduction, wastewater treatment, etc. In this context, the optical properties of transition metal oxalates, which have shown promising results as anode materials for lithium-ion batteries, have not been explored. This study presents the application of Cobalt oxalate as a visible light active photocatalyst. CoC2O4 nanorods had been synthesized by a facile hydrothermal treatment with cobalt nitrate and oxalic acid as precursors, tetrahydrofuran (THF) as a solvent and cetyl trimethyl ammonium bromide (CTAB) as a cationic surfactant. Cobalt oxalate nanocrystals were formed by a simple exchange reaction, and the synthesized catalyst was characterized by SEM, XRD, FTIR, TEM, TGA, and UV-Vis spectra analyses. Further, first principles DFT calculations were also performed to establish the geometric and electronic configuration of the synthesized catalysts, which was found to be in good agreement with the experimental results. The synthesized nanorods showed robust photocatalytic activity in the degradation of narcoleptic drug amphetamine, achieving 92% degradation in 90 minutes.
