Co3O4 nanoparticles assembled coatings synthesized by different techniques for photo-degradation of methylene blue dye

Synthesis and investigation of the electrical and dielectric properties of Co3O4/(CMC+PVA) nanocomposite films

“…Co 3 O 4 in the form of microspheres [34,36], nanoplates and nanobelts [38] have been prepared by hydrothermal processes. Co 3 O 4 NPs were prepared via several methods including solvothermal [32], chemical precipitation [37], pulsed laser deposition (PLD), electron beam deposition, sol-gel techniques [39], and by the thermal decomposition of the [(NH 3 ) 5 Co(O 2 )Co(NH 3 ) 5 ](NO 3 ) 4 ] [40]. In addition, nanosized Co 3 O 4 thin films were also prepared using sol-gel spin coating technique [35].…”

Hierarchical macro- and mesoporous assembly of metal oxide nanoparticles derived from metal-organic complex

“…Methylene blue (MB), as a typical industrial pollutant, is generally chosen as a model to examine the photocatalytic effect [54]. The Co 3 O 4 synthesized was used to catalyze the photocatalytic degradation of MB solution under visible light irradiation [55,56]. The variation of the relative concentration of the remaining MB dye in solution vs irradiation time was measured from the absorbance at 664 nm (Fig.…”

Influence of the preparation method on the catalytic activity of Co/Zr1−xCexO2 for NO oxidation

“…Combined with the results of BET, though the crystallite size of CCseries was smaller than that of IM-series, the similar BET surface area was obtained for these two series. This suggested that there may be some contribution to X-ray line broadening from disorder [15].…”
