TiO2-based ultraviolet photodetectors have drawn great attention and are intensively explored. However, the construction of TiO2-based nanocomposites with excellent ultraviolet responses remains challenging. Herein, a TiO2 nanorod array was successfully prepared on fluorine-doped tin oxide (FTO) conductive glass by a one-step hydrothermal method. Then, polypyrrole (PPy)-TiO2 nanorod array composites were designed via subsequent in situ oxidative polymerization. The morphologies, structures, and photocurrent responses of the nanocomposites were systematically investigated. The results demonstrated that polypyrrole-TiO2 exhibited a stronger photocurrent response than pure TiO2 due to the p-n junction formed between n-type TiO2 nanorod arrays and p-type polypyrrole. The PPy-TiO2 composite obtained by deposition three times had the best photoelectric properties, exhibiting good performance with a sensitivity of 41.7 and responsivity of 3.5 × 10−3 A/W. Finally, the mechanism of the photoelectrical response of PPy-TiO2 composites was discussed, guiding the design of high-performance TiO2-based ultraviolet photodetectors.

“…[10] Titanium dioxide (TiO 2 ) is considered as an ideal active material for UV PDs due to its n-type semiconductor with a suitable bandgap (3.0-3.2 eV), [11] high carrier mobility (≈39 cm 2 V −1 s −1 ), [12] and non-toxicity. 1D TiO 2 (1D, for example, nanorods, nanotubes, nanowires)-based p-n junctions have been extensively investigated for self-powered UV PDs due to the large heterojunction contact area, [13,14] which can efficiently separate electron-hole pairs and minimize interfacial carrier recombination. Therefore, the selection of a suitable p-type wide band-gap semiconductor is critical in achieving exceptional device performance.…”

The efficient separation and extraction of holes can be attributed to the favorable properties possessed by the hole transport layer (HTL). Herein, a novel solution‐processable hybrid HTL based on CuBO2 and Ti3C2Tx MXene (CuBO2@MXene) is developed to enhance the performance of ultraviolet photodetectors (UV PDs). By optimizing the ratio of Ti3C2Tx MXene to CuBO2, the optimized responsivity and detectivity of the UV PDs based on the composite HTL have achieved 184 mA W−1 and 2.88 × 1013 cm Hz1/2 W−1 in self‐powered mode, respectively, and even up to 3.25 × 104 mA W−1 at −1.5 V. This significant improvement in device performance can be attributed to the interlaced architecture of CuBO2@MXene, which ameliorates hole mobility and charge extraction capability while reducing the trap state density of the HTL. The built‐in electric field of the TiO2/CuBO2 heterojunction is strengthened by the incorporation of Ti3C2Tx MXene, thereby significantly reinforcing the photovoltaic effect. Moreover, the lower thermal conductivity of CuBO2@MXene suppresses its pyroelectric effect, weakening the blocking effect of the thermoelectric potential on hole transport and ultimately leading to a remarkable boost in the output current. These results indicate the promising potential of the hybrid CuBO2@MXene HTL for constructing high‐performance optoelectronic devices.

Copper oxide−zeolite (CuO−ZT) reinforced polyaniline (PANI) matrices were prepared by in situ oxidative polymerization and the samples were characterized by X‐ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, XRD, TGA, UV–visible spectrophotometry, SEM and Brunauer–Emmett–Teller theory; the optical bandgap was also evaluated. Moreover, the synthesis and exploration of electrodes are increasingly being considered for the development of conducting‐polymer‐based supercapacitors, which has attracted significant interest in energy conversion and storage technology. Here, hybrid materials used in the preparation of the electrode materials on the capacitive properties were investigated. It is found that the PANI@CuO exhibits a high specific capacitance of 311.5 F g−1 at 1.0 A g−1 current density between 0.0 and 1.0 V compared to PANI@CuO−ZT (222.7 F g−1). Further, the PANI@CuO presented an excellent cycling stability at 1.0 A g−1 (1500 cycles; 81.9%) in a two‐electrode system. Accordingly, producing a PANI matrix on CuO presented a simple and viable way to ameliorate the capacitive performance of the supercapacitor. Conversely, the adsorptive removal of malachite green and methyl violet dyes by PANI@CuO−ZT adsorbent could be described by the pseudo‐first‐order and Temkin models. The maximum adsorptive capacity of malachite green and methyl violet dyes was 249.7 and 198.2 mg g−1, respectively. © 2023 Society of Industrial Chemistry.
