A significant photocatalytic activity was achieved using Cu2O surrounded by Zn-Fe layered double hydroxide (LDH) for the degradation of Congo Red (CR) under solar radiation. Photocatalytic tests were conducted with Cu2O, Zn-Fe LDH, and Cu2O@Zn-Fe LDH, with experimental conditions optimized for complete CR degradation. The physical and optical properties of Cu2O, Zn-Fe LDH, and Cu2O@Zn-Fe LDH were correlated with photoelectrochemical characterization to establish the energy diagram of the Cu2O@Zn-Fe LDH core-shell/electrolyte system. UV–visible spectroscopy revealed bandgap values of 2.04 eV for Cu2O and 2.24 eV for Zn-Fe LDH, corresponding to directly allowed transitions. Flat band potentials, determined from capacitance-potential plots, were -0.32 V/SCE for Cu2O and 0.13 V/SCE for Zn-Fe LDH. Visible light absorption induced electron transfer from the conduction band of Cu2O (-2.05 V/SCE) to the shallow trapping sites of Zn-Fe LDH (-0.79 V/SCE), enhancing charge carrier separation and accelerating CR degradation. Under solar illumination and optimized conditions (pH ∼ 6.78, T ∼ 25 °C, catalyst dose of 1 mg/mL), complete degradation of 10 mg/L CR was achieved, with total organic carbon analysis confirming mineralization. The Density Functional Theory (DFT)-optimized structure of CR dye was analyzed to predict reactive sites using Fukui functions, the dual descriptor , local, softness Δσk, and local philicity Δωk. The analysis identified the most favorable sites for nucleophilic attack as the N13 (0.0299) and N14 (0.0357) atoms. Based on dynamic and Monte Carlo simulations, the Zn–Fe LDH and Cu2O@Zn-Fe LDH surfaces exhibited the highest adsorption energy for CR dye, resulting in strong adsorption. This finding is consistent with our experimental studies.
