A novel [ZrO2 + BTB]C nanocomposite was synthesized and prepared as a thin film using the Sol-Gel spin coating method. Different characterization techniques for [ZrO2 + BTB]C like FTIR, UV-Vis, and optical properties have been used. The resulted XRD and SEM data have been employed to study interface composites. The optimization was performed using DFT by DMol3 and CASTEP program. The chemical structure was confirmed by spectroscopic and structural properties for [ZrO2-BTB]C, XRD results showed the same crystal structure. Combined between experimental and TDD-DFT data, the average crystallite size and composite interface are 12.36 nm and orthorhombic symmetry (a = 7.38(5); b = 18.178(6); c = 26.10(3) Å and a = b = g = 90o) with space group (P61) for [ZrO2 + BTB]C, respectively. Furthermore. While the computed by DFT are 2.897 eV and 2.492 eV for as-isolated crystals of [BTB]TF and [ZrO2 + BTB]C, respectively. Both [BTB]TF and [ZrO2 + BTB]C thin films have direct allowed transitions. In addition, the optoelectrical parameters have been calculated for [BTB]TF and [ZrO2 + BTB]C films such as refractive index, extinction coefficient, dielectric constant, and optical conductivity. The simulated values obtained by CATSTEP for the optical parameters of [ZrO2 + BTB]C are in good agreement with the experimental values. The [ZrO2 + BTB]C presents a good candidate for optoelectronics and solar cell applications.

“…Again, the product was also defined by the FTIR spectral bands 54–56 observed at frequency 3636 cm −1 that define the −OH group in BTB and this band is shifted to 3430 cm −1 ; so this indicates the oxidation occurs in the hydroxyl group. Finally, the band found at 1593 cm −1 54–56 characterizing the carbonyl group with related ketones; a strong band occurs at 3157 cm −1 characterizing the CH 2 group 57–59 in the case with BTB while it seems to be the weak band at 2954 cm −1 in the case of keto‐BTB characterizing the −CH group 60–61 . Enhancement of the OH group's absorption band at a wavenumber of 1593 cm −1 in the product's FTIR spectra that mean oxidation of the OH group present in BTB dye to its corresponding keto‐forms as shown in Figure 2.…”

Spectrophotometric analysis was applied to check the kinetics of bromothymol blue (BTB) oxidation by alkaline permanganate at constant ionic strength 0.2 mol dm−3. The redox reaction was observed to proceed through two independently distinct, detectable steps. The first step coexists with the formation of intermediate complexes involving transient species relatively quickly of the blue hypomanganate(V) and green manganate(VI). The slowly decomposed intermediate formed to produce soluble colloidal manganese(IV) and the BTB keto‐derivatives as second slow‐stage oxidation products. The oxidation reaction demonstrated first‐order dependence in [MnO4−] and fractional first‐order kinetics at each of the BTB and alkali concentrations at an initial rapid stage for complexes formation. It was found that the oxidation process is of a base‐catalyzed nature. Novel spectrophotometric measurement of the blue hypomanganate(V) was introduced using a traditional spectrophotometer. An effective oxidation mechanism compatible with the kinetic data obtained in terms of the activation parameters assessed was analyzed, proposed, and discussed in line with the kinetic findings.

“…The elemental analysis and the FT IR spectra identified the development of oxalic acid as the sugarcane molasse oxidizing agents and FTIR of formic acid. As seen in the FT IR spectra (Figure 2), at 1740-1720 cm -1 (broad) a strong IR absorption band was observed, which characterized the carboxylic acid carbonyl group [36][37][38]. The improvement in the absorption band of the OH group in the IR spectra at a wavenumber of 1700 cm -1 again suggests the oxidation of the carboxylic acid OH groups to the keto (C = O) type.…”

Oxalic acid in alkaline medium was quantitatively synthesized using sugarcane molasse oxidation (SCM) by potassium permanganate as oxidizing agent. The produced compound was identified using Fourier Transform Infrared (FT IR), mass spectra and with by reaction with 2,4-dinitrophenyl hydrazine and hydroxylamine reactions have been identified as the oxidation product (oxalic acid), which gives negative results in 2,4-dinitrophenyl hydrazine and hydroxylamine. It has been found that the oxidation portion has a strong chelation affinity with most mono-and divalent complexes that provide stable high chelating agents and therefore one of the most abundant organic acids in the plant. Again, the formic acid was prepared from the result of oxidation (oxalic acid) and by FT IR.
