“…Doping and loading of donor elements into ZnO structures have been widely studied to improve the stability, photoelectrical and optical properties of ZnO nanostructures [ 12 , 17 , 19 , 28 , 40 , 59 , 99 ]. Tsay et al showed that the co-doping of Ga and In ions into ZnO crystal significantly improved the photoelectrical properties and increased the p-n heterojunction UV PDs’ stability more than single doping of Ga or In [ 110 ].…”

Ultraviolet (UV) sensors offer significant advantages in human health protection and environmental pollution monitoring. Amongst various materials for UV sensors, the zinc oxide (ZnO) nanostructure is considered as one of the most promising candidates due to its incredible electrical, optical, biomedical, energetic and preparing properties. Compared to other fabricating techniques, hydrothermal synthesis has been proven to show special advantages such as economic cost, low-temperature process and excellent and high-yield production. Here, we summarize the latest progress in research about the hydrothermal synthesis of ZnO nanostructures for UV sensing. We particularly focus on the selective hydrothermal processes and reveal the effect of key factors/parameters on ZnO architectures, such as the laser power source, temperature, growth time, precursor, seeding solution and bases. Furthermore, ZnO hydrothermal nanostructures for UV applications as well as their mechanisms are also summarized. This review will therefore enlighten future ideas of low-temperature and low-cost ZnO-based UV sensors.

In this paper, the development of regenerated cotton linter cellulose membranes embedded with ZnO nanoparticles was conducted using the dissolution-regeneration process. The physical and chemical properties of composite membranes were characterized using X-ray diffraction, field-emission scanning electron microscopy, Fourier-transform infrared spectroscopy, ultraviolet-visible spectroscopy, and thermogravimetric analysis. The characterizations revealed that the addition of ZnO nanoparticles changes the crystallinity, bond properties, thermal properties, and hydrophilicity of the regenerated cellulose membrane. These nanocomposite membranes demonstrated good capability in water absorption, with pore volumes ranging from 3.6 to 2.1 cm 3 /g. In the photocatalytic studies, the cellulose membranes incorporating ZnO particles (1.6 wt%) can remove up to 87.6% of MB in 100 min under UV irradiation and also maintained reusability (84%) after sixth cycles after 6 months.Taken together, this bifunctional cellulose/ZnO membrane is a promising material for solving the wastewater crisis.

The co‐precipitation approach was employed in this study to create Fe doped ZnO (Fe‐ZnO) nanoparticles (NPs). To characterize the synthesized NPs, Ultra violet‐Visible (UV‐Vis) spectroscopy, X‐ray diffraction (XRD), fourier transform infrared (FT‐IR), scanning electron microscopy (SEM), and Brunauer‐Emmett‐Teller (BET) were used. Here, a novel electrochemical approach for the detection of tryptophan (Trp) using a glassy carbon electrode modified with Fe‐ZnO NPs (Fe‐ZnO/GCE) is demonstrated. The research findings revealed that Fe‐ZnO/GCE enhanced the electron transfer rate of Trp oxidation. The sensitivity of Trp detection using Fe‐ZnO/GCE in phosphate buffer solution (PBS) at pH 64.0 was significantly improved compared to bare GCE due to the electrocatalytic activity of Fe‐ZnO NPs. Fe‐ZnO/GCE exhibited a linear response with Trp concentrations ranging from 0.1 to 150 μM with the limit of detection (LOD) is 0.089 μM (3σ/m) and limit of quantification (LOQ) about 0.3 μM (10σ/m) using linear sweep voltammetry (LSV). The Fe‐ZnO/GCE sensor was also effectively used to detect Trp in African catfish and multivitamin tablets. Trp analysis in real samples exhibited good recovery values of 89.60 to 99.15 %, demonstrating the accuracy and practicality of the method.
