Does the peak formation of metal oxide differ with the combination?
Zn-O bond formation in metal oxides used to arrive around 400 to 450 cm-1, but when it comes to bimetallic oxides like ZnM2O4 (M=Co, Fe, Cr, etc..)the Zn-O bond formation range varies to a higher wavenumber near 599 cm-1 and M-O moves on to lower wavenumber.
How can we confirm our material's bond formation? what influence this shift?
Dear friend Roshan Chandrapal R
Yes, the peak formation of metal oxide can differ with the combination when it comes to bimetallic oxides. The shift in the wavenumber of the bond formation peak can provide information about the bonding environment and coordination of metal ions in the oxide lattice.
To confirm the bond formation in a material, Fourier transform infrared (FTIR) spectroscopy is commonly used. In FTIR, infrared radiation is passed through the sample and the amount of radiation absorbed at different wavelengths is recorded. The resulting spectrum provides information about the chemical bonds and functional groups present in the material.
The shift in the bond formation peak can be influenced by several factors such as the electronic environment of the metal ions, the lattice structure of the oxide, and the oxidation state of the metal ions. For example, the presence of a second metal ion in the oxide lattice can affect the electronic environment and coordination of the metal ions, resulting in a shift in the bond formation peak.
Other techniques such as X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) can also be used to confirm the bonding environment and coordination of metal ions in the oxide lattice.
The shift in the Zn-O bond formation range and the M-O bond in bimetallic oxides like ZnM2O4 can be attributed to the change in the electronic and structural properties of the oxides.
The change in the crystal structure leads to the modification of the bond angles and bond lengths, which affects the vibrational frequencies of the chemical bonds in the oxide.
