“…The intrinsic structural peaks of PANI can also be observed at 1196 cm −1 around the C-H plane bending vibration (benzene structure), 1293 cm −1 around the protonated structure, 1376 cm −1 around the C-N+ stretching vibration (semiquinone ring), 1569 cm −1 around the C=C stretching vibration (quinone structure), and 1621 cm −1 around the C-C stretching vibration in the benzene ring (benzene structure). A C-C stretching vibration in the benzene ring (benzene structure) occurs near 1621 cm −1 [46,50]. nanocomposites are shown in Figure 4b.…”

TiO2 has great potential for application in UV photodetectors due to its excellent photoelectric response. In this work, composite nanomaterials of TiO2 nanotube arrays (TiO2 NTAs) and polyaniline (PANI) were successfully prepared on titanium sheets using an anodic oxidation electrochemical method. The results showed that the TiO2 NTA/PANI composite materials had excellent UV photosensitivity and responsiveness and good stability and reproducibility. This was mainly attributed to the p–n heterostructure formed inside the TiO2 NTA/PANI composites that hindered the recombination of photogenerated electron–hole pairs and improved their utilization of UV light. This work provides a theoretical basis for the application of metal oxides in UV photodetectors, which is important for the development of UV photodetectors.
