Abstract A ternary nanohybrid CuO/Mn 3 O 4 /CeO 2 was developed in the present work using a co-precipitation-assisted hydrothermal method. The designed photocatalyst's structural, morphology, elemental composition, electronic states of elements, and optical properties were studied corresponding analytical techniques. Results from PXRD, TEM/HRTEM, XPS, EDAX, PL showed that desired nanostructure had formed. Using Tauc's energy band gap plot, it determined nanostructures ~ 2.44 eV, which margins various moieties, CeO , Mn CuO, modified. Thus, improved redox conditions led to substantial decrease recombination rate electron–hole pairs, further explained by study charge separation plays key role. Under exposure visible light irradiation for 60 min, revealed photocatalyst achieved 98.98% photodegradation efficiency malachite green (MG) dye. process proceeded according pseudo-first-order reaction kinetic model with an excellent 0.07295 min −1 R = 0.99144. impacts different variables, inorganic salts, water matrices investigated. This research seeks create high photostability, spectrum activity, reusability up four cycles.
