Abstract
A sequence of Schiff base Cobalt (II) Mobile Composite Matter 41 heterojunction (SBCo(II)-MCM 41) was prepared by post-synthetic protocols. Various characterization techniques were used to characterize the above samples and MCM 41: Morphology, functional groups, optical properties, crystalline nature, pore diameter, and binding energy by scanning electron microscope (SEM), High-resolution transition electron microscopy (HR-TEM), Fourier transform infrared spectroscopy (FTIR), Ultra Violet-Visible Spectroscopy (UV), X-ray powder diffraction (XRD), Brunauer-Emmett-Teller (BET) and X-ray Photoelectron Spectroscopy (XPS). After the encapsulation of SBCo(II) on the MCM 41, the intensity in the 100-plane in powder x-ray diffraction (XRD) decreased significantly; moreover, the light absorption behavior in UV analysis was improved. The change in the surface area and the decrease in the pore diameter of the sample were also demonstrated by the BET study. The XPS results confirmed the presence of Si, O, C, N, and Co in the SBCo(II)-MCM 41 complex. The photocatalytic performance of MCM 41 and SBCo(II)-MCM 41 materials tested by the degradation of methylene blue dye (MBD) shows that MCM 41 immobilization with SBCo(II)complex is rapidly degraded under natural sunlight irradiation. The optimized 10 mg SBCo(II)-MCM 41 catalyst concentrations showed effective enhancement with the highest efficiency of 98% achieved within 2 h compared to the other two SBCo(II)-MCM 41 concentrations. Moreover, the catalytic efficiency of SBCo(II)-MCM 41 showed a biomimetic reaction without using an oxidant, which exposed it as an effective catalyst for amine to imine conversion; it was useful in the medical field for enzymes with structural assembly.

Abstract
Herein, Co3O4/CeO2 nanocomposite was synthesized by the modified Pechini method. Citric, maleic, succinic, and trimsic acids were used as a stabilizer, and the variation affected the morphology and size of the synthesized nanocomposites. Subsequently, the formation of Co3O4/CeO2 nanocomposites was confirmed by various analyses. Furthermore, the particles were considered for size and morphology by SEM and HRTEM analyses, and the sample that used trimsic acid as the stabilizer was designated as the goal sample to continue the route. The optimum sample was used to investigate the photocatalytic properties of the synthesized nanocomposite. The UV-light photocatalyst test was performed in neutral, alkaline, and acidic states against two aqueous solutions containing color contamination of methylene blue and erythrosine B dyes. The results showed decolorization at 85% for methylene blue and 90% for erythrosine B over 120 min test time.
