“…The PANI/TiO 2 nanocomposite thin film was synthesized by magnetron sputtering and plasma polymerization, and PANI/TiO 2 -based UV PDs were prepared. 54 The UV PD exhibited very high photoresponse under UV irradiation of 0.4 mW/cm 2 , which shows that the UV PD has great potential for application as a high-sensitivity UV PD. The optoelectronic properties were investigated, 55 which are sensitive to UV light along with a light-dark current pair of 381 at −1 V and a barrier height at zero bias of 0.73 eV, a responsivity of 24.9 A/ W, and a lift-off/falloff time of 0.6/1.6 s. The mechanism of the significant photocurrent enhancement by Al/F−Cl−TiO 2 / CSA-PANI was elucidated by using the proposed energy band model.…”

Wide band gap TiO2 with high light absorption coefficient, high crystallinity, and high carrier mobility is widely used to assemble ultraviolet photodetectors (UV PDs) with high performance. Based on the strong attractiveness from its advantages such as high stability and excellent photoelectric properties, the construction of high-performance TiO2-based UV PDs has been extensively developed. Conducting polymers with high carrier mobility and good electrical conductivity can make up for the shortcomings of TiO2-based UV PDs to achieve efficient TiO2-based UV PDs with high photoelectric performances. In this paper, we present an in-depth review of the preparation process of TiO2 with conducting polymers and their complexes and introduce the principle, classification, and main evaluation parameters of UV PDs. In addition, this paper reviews that TiO2/polymer UV PDs have exhibited different optoelectronic properties (responsivity, switching ratio, detectivity, response time, etc.). Finally, it looks at the future of TiO2-based UV PDs research and the major challenges that need to be addressed, particularly that of further functional applications. This review lays the foundation for solving current technical problems and provides insights into the preparation of a more efficient TiO2/conductive polymer for future photovoltaic applications.

The continuous upsurge in water pollution caused by harmful organic and inorganic contaminants has led to a shortage of nontoxic, clean water and effective waste management. Therefore, it is crucial to establish an eco-friendly approach using sustainable, biodegradable, and recyclable materials to treat the wastewater. In this regard, photocatalysts are highly effective for mitigating water pollution to a certain degree through an energy-efficient and greener approach. Among various photocatalysts, polymeric nanocomposites have attracted considerable consideration owing to their several advantageous characteristics like higher surface area, extended surface to volume ratio, advanced adsorption efficiency, and application for the degradation of harmful contaminants. In this comprehensive review, we have focused on the recent synthetic approaches for development of polymeric nanocomposites. Also, the application of these polymeric nanocomposites for the degradation of harmful contaminants has also been extensively summarized. This article further extensively discusses the process of photocatalysis to provide a clear understanding to the reader.

“…In order for meeting these practical uses, DUV OPDs are required to harbor high quantum efficiency. It is well known that efficient dissociation of photo-induced excitons is crucial in determining quantum efficiency, which can be achieved within charge transfer between donor-acceptor interfaces [4,[7][8][9]. Such donor-acceptor interfaces can been implemented by planar heterojunctions (HJs) [10][11][12][13], bulk HJs [7,8,14,15], and mixed planar-bulk HJs (PBHJs) [16][17][18].…”
