One-step synthesis of versatile PbMoO₄@CdMoO₄ microspheres hybrid for the enhanced photocatalytic dye degradation

In this work, we have demonstrated the productive synthesis of novel and versatile CdMoO₄@PbMoO₄ microspheres hybrid photocatalysts by a simple chemical reduction process. Fabricated CdMoO₄@PbMoO₄ hybrid microsphere characteristics were analyzed by various techniques to ascertain their structural and morphological properties. The photocatalytic degradation properties of CdMoO₄@PbMoO₄ hybrid microspheres were evaluated against methylene blue (MB) and congo red (CR) colorants under visible light. The hierarchical structure of CdMoO₄@PbMoO₄ along with the modulated bandgap, interfacial valence state electrons shift, and quick conversion of the Cd²⁺/Pb²⁺ cycle led to the display of the 98 % and 97 % degradations of CR and MB under visible light treatment, respectively which is superior to the corresponding pure structures degradation efficiency, signifying their boosted catalytic properties. Furthermore, the degradation mechanism endorsed excellent dye photodegradation under visible light illumination by the novel CdMoO₄@PbMoO₄ microspheres hybrid catalyst. The observations gave more insight into the progress of the advancement of CdMoO₄@PbMoO₄ microspheres hybrid to effectively detoxify perilous and toxic water effluents for industrial purposes.
