Facile Synthesis of Co₃O₄ Cubic Structures and Evaluation of Their Catalytic Properties

Abstract

Co 3 O 4 cubic structures have been successfully prepared using the thermal decomposition of precursors approach. The precursor cubic structures were synthesized using a facile chemical precipitation method. X-ray diffraction, thermal gravimetric analysis, scanning electron microscopy, and UV-vis and infrared spectroscopy were used to characterize the products. The results showed that the reaction time and the nature of the surfactant played important roles in the formation of the products. The measurement of the catalytic activity of the as-prepared Co 3 O 4 particles revealed that they played a photocatalytic role in the degradation of methyl violet.

Synthesis, crystal structure, and characterization of cyclohexylammonium tetraisothiocyanatocobaltate(II): A single-source precursor for cobalt sulfide and oxide nanostructures

“…Cobalt sulfide finds widespread applications such as electrochemical conductivity [23, 24], electrochemical water splitting with photo anodes [25, 26], and supercapacitors with enhanced charge capacity and stability [27, 28]. On the other hand, tricobalt tetraoxide (Co 3 O 4 ) has been reported for use in supercapacitors, magnetic semiconductors [29, 30, 31], photocatalysis [32, 33], carbon monoxide (CO) and hydrocarbon oxidations, and other catalysis applications [34, 35, 36, 37, 38].…”

Ligand-assisted soft-chemical synthesis of self-assembled different shaped mesoporous Co3O4: efficient visible light photocatalysts

“…The photocatalytic role of Co 3 O 4 has been reported by many researchers. [28][29][30][31] Warang et al showed the photocatalytic efficiency of Co 3 O 4 for degradation of methylene blue via the photo-Fenton reaction. 28 Photocatalytic degradation of methyl violet in the presence of Co 3 O 4 catalysts has been reported by Li et al 29 Lou et al synthesized Co 3 O 4 nanorods, and studied photocatalytic degradation of different active dyes.…”
