“…Compared with pure TiO 2 sample, we can infer that the C=O bonds in the C-TiO 2 and Mn-C-TiO 2 samples could be attributed to the T80 used in the sol. In the region below 1000 cm −1 , this peak was ascribed to absorption bands of Mn-O, which could be inferred that some manganese oxide may appear on the surface of TiO 2 nanoparticles [28].…”

Novel visible-light-active Mn–C–TiO2nanoparticles were synthesized by modified sol-gel method based on the self-assembly technique using polyoxyethylenes orbitan monooleate (Tween 80) as template and carbon precursor and manganese acetate as manganese precursor. The samples were characterized by XRD, FTIR, UV-vis diffuse reflectance, XPS, and laser particle size analysis. The XRD results showed that Mn–C–TiO2sample exhibited anatase phase and no other crystal phase was identified. High specific surface area, small crystallite size, and small particle size distribution could be obtained by manganese and carbon codoped and Mn–C–TiO2exhibited greater red shift in absorption edge of samples in visible region than that of C–TiO2and pure TiO2. The photocatalytic activity of synthesized catalyst was evaluated by photocatalytic oxidation of methyl orange (MO) solution under the sunlight irradiation. The results showed that Mn–C–TiO2nanoparticles have higher activity than other samples under sunlight, which could be attributed to the high specific surface area, smaller particle size, and lower band gap energy.

“…5a shows the high-resolution Mn 2p XPS spectra of Mn-C-TiO 2 . The two Mn 2p peaks at the binding energy of 640.5 and 653.0 eV indicate the existence of MnO 2 [28]. The C 1s XPS spectra of TiO 2 and Mn-C-TiO 2 -400 were shown in Fig.…”

“…The chemical interactions of fillers with the LDPE matrices were studied using FTIR spectroscopy, as shown in Figure 4. The pristine LDPE film demonstrates unique absorbance peaks at 2913, 2853, 1472, 1463, 729, and 719 cm −1 which correspond to CH 2 bending and stretching vibrations of the LDPE network [46]. The chemical composition of LDPE did not change after the addition of TONPs and/or CNTs.…”

This work aims to investigate the effect of hybrid filler concentration on the thermal stability of low-density polyethylene (LDPE) matrices. LDPE-based composite films were synthesized by melt mixing, followed by compression molding, to study the influence of titanium oxide nanoparticles (TONPs) and/or multi-walled carbon nanotubes (CNTs) on the thermal properties of LDPE matrices. Fourier transform infrared (FTIR) spectroscopy confirmed the slight increase in the band intensities after TONP addition and a remarkable surge after the incorporation of CNTs. The value of crystallization temperature (Tc) was not modified after incorporating TONPs, while an enhancement was observed after adding the hybrid fillers. The melting temperature (Tm) was not changed after introducing the CNTs and CNT/TONP hybrid fillers. The percentage crystallinity (Xc %) was increased by 4% and 6%, after incorporating 1 wt % and 3 wt % CNTs, respectively. The TONP incorporation did not modify the Xc %. Moreover, thermal gravimetric analysis (TGA) thermograms confirmed the increased thermal stability after introducing CNTs and hybrid fillers compared to TONP incorporation.
