“…However, further catalytic performance improvements of ZnO by using a green synthesis method are also needed. For this purpose, the biological renewable plant materials can be used as a template to prepare oxide semiconductorbased photocatalysts [29,30]. Among the biological renewable unwanted plant materials resources is Eichhornia crassipes.…”

The Cr-doped ZnO photocatalysts were synthesized through the chromium ion accumulations by water hyacinth (Eichhornia crassipes). In the preparation process, the plant tissues were immersed in different sample flasks containing chromium precursors for 1, 2, 4, 6, and 8 days. The plant tissue containing chromium ion was mixed with zinc precursor followed by calcinations. For simplicity, the prepared Cr-doped ZnO samples with the plant immersed for 1, 2, 4, 6, and 8 days were abbreviated as D1, D2, D4, D6, and D8, respectively. Moreover, pure ZnO was also prepared without the water hyacinth plant accumulated with chromium ion for comparison purposes. The powder sample characterizations were performed and evaluated in the degradation of methylene blue (MB). The Cr-doped ZnO sample (D1) degrades 80% of MB dye while the D2, D4, D6, D8, and pure ZnO samples degrade only 74, 76, 79, 73, and 25%, respectively. On the other hand, without the addition of catalysts (blank), there was no significant degradation of MB dye within 90 min irradiation. Therefore, the degradation performance of Cr-doped ZnO in the presence of optimum amount of chromium dopant and water hyacinth is highly improved than that of pure ZnO. The catalytic improvement may be as a result of reducing the photogenerated electron and hole recombination rates due to the presence of dopants. Moreover, the presence of the Eichhornia crassipes plant in the synthesis of Cr-doped ZnO could also prevent further aggregations and particle size growth and enhance the porosity after calcination.

“…This section focuses on three exemplary preparation methods of nanocomposite and nanoparticles (NPs) or nanocomposites with synthesized NPs as summarized by Table 4. Nanocellulose (CNP) hybrids with metal oxide (MeO) applications were proven to be enhanced for instance in photocatalytic treatment (Shi et al, 2021), food industry (Reis et al 2021), and biomedical industries (Oprea & Mihaela Panaitescu, 2020). In these three examples, various cellulosic feedstock ranging from soft wood, cellulosic waste and to bacterial cellulose were investigated and fabricated in hybrid with common steps starting with pretreatment of cellulosic biomass for instance ultraviolet (UV) treatment or steam explosion and via generation of cellulose (for bacterial mode), to synthesis of MeO NPs either in situ or ex situ and finally the final preparation of the readied nanocomposites of MeO/CNPs.…”

“…Methyl orange dye was treated in a photocatalysis with Ag-ZnO/cellulose nanocomposite (acting as nanocatalyst) which was found to have enhanced photocatalytic activities, improved recovery, catalyst stability, and reusability (Shi et al, 2021). Bionanocomposite from plain parchment fiber for instance polycaprolactone (PCL) reinforced nanocomposite with ZnO nanoparticle was investigated for food packaging film with enhanced mechanical strength, thermal stability, characteristics, and gas barrier permeability coefficient for carbon dioxide (Reis et al, 2021).…”

Cellulosic fiber (CF) in nanoform is emergingly finding its way for COVID-19 solution for instance via nanocomposite/ nanoparticle from various abundant biopolymeric waste materials, which may not be widely commercialized when the pandemic strikes recently. The possibility is wide open but needs proper collection of knowledge and research data. Thus, this article firstly reviews CF produced from various lignocellulosic or biomass feedstocks' pretreatment methods in various nanoforms or nanocomposites, also serving together with metal oxide (MeO) antimicrobial agents having certain analytical reporting. CF-MeO hybrid product can be a great option for COVID-19 antimicrobial resistant environment to be proposed considering the long-established CF and MeO laboratory investigations. Secondly, a preliminary pH investigation of 7 to 12 on zinc oxide synthesis discussing on Fouriertransform infrared spectroscopy (FTIR) functional groups and scanning electron microscope (SEM) images are also presented, justifying the knowledge requirement for future stable nanocomposite formulation. In addition to that, recent precursors suitable for zinc oxide nanoparticle synthesis with emergingly prediction to serve as COVID-19 purposes via different products, aligning with CFs or nanocellulose for industrial applications are also reviewed.
