“…Figure 3 shows the Raman spectra of the TiO2 films these spectrums present vibrational modes at Eg (144 cm -1 , 197 cm -1 , and 638 cm -1 ), B1g (399 cm -1 and 519 cm -1 ), A1g (519 cm -1 ) confirming the presence of TiO2 anatase phase [9], with the increase of temperature the vibrational modes increase their intensity. The vibrational mode with the highest intensity is Eg(144 cm -1 ) which is related to a particle size smaller than 40 nm and is confirmed by the calculated grain size of the preferential plane (101) [10]. The B1g modes correspond to the vibration of titanium atoms and the A1g mode to the vibrations of oxygen atoms, the peak at 519 cm-1 is superimposed with the B1g(2) mode so the increase of A1g + B1g is due to the oxygen vacancies [11].…”

“…Recently, pollution, especially organic dyes afecting water resources, has become quite serious. With the background of energy utilization and environmental protection, the photo-degradation of organic pollutants has been actively studied (Medda et al, 2020;Cheng et al, 2021a;Wang et al, 2021a). To reduce the pressure on the environment caused by organic pollutants, many processes including ozone-oxidation method, photo-degradation method, activated-carbon adsorption method, and so on have been designed to degrade the organic pollutants (Caballero-Espitia et al, 2020;Wang et al, 2021b;Wang et al, 2021c).…”

“…[23][24][25]. Doping with carbon nanostructures leads to the formation of interfacial heterostructural transitions, an increase in interphase boundaries, as well as conductivity, which has a significant effect on the photocatalytic properties of ceramics [26][27][28][29][30].…”
