“…The ZnO is also used in the dye removal process effectively because of excellent adsorption coefficient by virtue of its surface morphology and volume to surface ratio. Hence the zinc oxide nanoparticles attached to polyacrylonitrile nanofibers with hinokitiol as gluing agent for synergistic antibacterial activities and effective dye removal [28]. And the ZnO nanofibers are prepared by electrospinning used in the solar cells.…”

In this review work, we highlight the origin of morphological structures such as nanofibers/nanorods in case of various materials in nano as well as bulk form. In addition, a discussion on different cations of different ionic radii and other intrinsic factors is provided. The materials (ceramic titanates, ferrites, hexaferrites, oxides, organic/inorganic composites, etc.,) exhibiting the nanofibers/nanorods like morphological structures are tabulated. Furthermore, the significance of nanofibers/nanorods obtained from distinct materials is elucidated in multiple scientific and technological fields. At the end, the device applications of these morphological species are also described in the current technology.

“…Recently, ZnO has excellent performance in purifying organic and inorganic pollutants from wastewater, such as removing arsenic (Sharma et al, 2019b), chromium (Sharma et al, 2019a) and dyes (Phan et al, 2020). These behaviors may be derived from the high adsorption e ciency, antibacterial ability (Bhutiya et al, 2018;Zhao et al, 2018), and chemical stability of ZnO making it exhibit fantastic adsorption capacity when eliminating various contaminations from wastewater.…”

“…For instance, Zhang and coworkers prepared a layered mesoporous nano-TiO 2 /cellulose composite material by microwave-assisted method for rapid adsorption of Pb 2+ in wastewater (Zhang et al, 2017), but the application of composite material has been restricted by the inherent interaction of cellulose with proteins, bacteria, and other foulants, which seriously damage the adsorbent and affect the ability of the adsorbent (Fakhre and Ibrahim, 2018). Based on the above defects, Phan et al successful fabricated ZnO-HT-PAN, indicating that the ZnO nanoparticles attached to nano bers can improve the antibacterial ability (Phan et al, 2020). However, the antibacterial ability of only ZnO is limited in practical applications.…”

Recovery of the tellurium from wastewater is signi cance for both industrial applications and sustainable development due to the adverse impacts emanating from environmental pollution and strategic values in the photovoltaic industry. Herein, this study presents the recovery of tellurium from wastewater by owerlike structure ZnO-Ag@cellulose (ZAC) composites. For adsorbent preparation, lignocellulose was rst extracted from waste wood debris by an alkaline extraction process. Then, the ower-like structure of ZAC composites were synthesized by a facile one-step hydrothermal method. The obtained materials are conducted under different parameters to investigate tellurium adsorption properties. The results indicate that the tellurium adsorption process is an exothermic reaction and ts well to the Freundlich model. Kinetic data are well described by pseudo-second-order model, indicating ZAC adsorption of tellurium is a chemical process. Besides, as-prepared ZAC exhibited excellent performance for tellurium elimination from wastewater with a maximum removal e ciency of 98.86%. The ZAC also shows outstanding antifouling performance in polluted environment and can still achieve the rate of 94.23% for tellurium. Moreover, the ZAC composite reveals high reusability and stability after six desorption-regeneration cycles. Importantly, the ZAC composite exhibits disinfection performance against E. coli and S. aureus with high killing e ciency. Therefore, this work not only demonstrates ZAC composite is e cient adsorbent with antifouling and antibacterial capability for tellurium recovery, but also provides an effective channel for promising candidates to decontaminate similar pollutants and practical applications of wastewater. Highlights 1. The ZAC composites were fabricated via a facile one-step hydrothermal method.2. The raw materials are extracted from waste wood debris using alkaline extraction process to extract lignocellulose.3. The prepared composite material has high antifouling and antibacterial ability for the adsorption of tellurium (IV). 4. The resulting composite material exhibits excellent performance, with a maximum removal rate of tellurium (IV) was 98.86%.5. The prepared adsorbent has excellent stability and reusable ability to remove tellurium in wastewater.

Magnetic beads composed by polyvinyl alcohol and iron oxides were developed and fully characterized. The materials were not only cross‐linked by a physical treatment but also the magnetic nanoparticles (MNPs) are acting as cross‐linking dots. Interestingly, the analysis of scanning electron micrographs revealed that, in the case of hydrated samples, flower‐like structures (average diameter 6–9 μm) being constituted by MNPs were present, whereas when the beads were dried the MNPs structure changed to porous spheres (average diameter 2–3 μm). Some of the prepared materials were tested to determine their capability to act as water remediation devices, and good removal results were obtained toward both methylene blue (average removal efficiency higher than 80%) and methyl orange (average removal efficiency lower than 30%) adsorption. The experiments performed confirmed that the adsorbent, once the treatment has ended, can be removed off through the simple employment of a permanent magnet.
