Effect of calcination temperature on structural, optical and antibacterial properties of ball mill synthesized Co3O4 nanomaterials

Structural and optical properties of green-synthesised tricobalt tetroxide nanoparticles

“…3 O 4 -NPs exhibit a smaller bond length than the results reported by Singh et al, where Co 3 O 4 nanomaterials were prepared through ball milling methods followed by calcination at more than 300 °C for 4 h, and the obtained values of Co 3+ -O 2− and Co 2+ -O 2− bond lengths were greater than 1.9 Å[54].…”

“…the O 2-→ Co 3+ or Co 3+ →Co 2+ charge transfer process is indicated by a broad hump in the range of 400 nm to 700 nm [74]. Using this UV-vis absorbance spectrum, the E g of Co 3 O 4 -NPs was determined by the following Tauc's equation [54]:…”

Experimental and DFT + U Investigations of the Cu1-xCdxO Nanoparticles Synthesized for Photocatalytic Degradation of Organic Pollutants: Environmental Application

“…Where λ represents the wavelength of the X-ray source, K ~0.9 (constant), θhkl is the diffraction angle and βhkl is the peak broadening [51][52][53]. Crystallite size and micro-strain have been calculated over the two most intense peaks and average values are listed in Table 1.…”
