“…In this study, a lower amount of catalysts will be used to degrade a large-scale synthetic dye. Besides, ZnONPs have exceptional stability in a variety of conditions [12]. Extensive researches investigated the stability of ZnONPs, as it is essential to evaluate the stability of catalysts for practical application.…”

In the current era of globalization, synthetic dyes are one of the key factors of water pollution. Photocatalysis constitutes a promising technology for the treatment of wastewater, especially to those containing hard-to-remove organic compounds. Zinc oxide nanoparticles (ZnONPs) play a vital role as a photocatalyst material. This research highlights the synthesized ZnONPs with roselle flower and oil palm leaf extract. The extracts and sodium hydroxide (NaOH) act as reducing agents during the synthesis process. Synthesis without the addition of plant extract is used as blank control for the experiment. Structural and optical studies of the three variants of ZnONPs were performed. High purity of ZnONPs with element Zn and O was obtained. The size of the three variants of ZnONPs was from 10–15 nm and found in agglomerated spherical shape. Large band gap, 3.2 eV was obtained by UV-Vis and high thermal stability was proven by TGA. Oxygen vacancies that assist in the degradation phenomenon were found in ZnONPs. Five percent of ZnONPs with the presence of 10 W UV light could effectively degrade 10 ppm MO in 5 h and MB in 3 h. Besides, high antioxidant properties and low toxicity demonstrated the ability of ZnONPs to be used as photocatalysts. In conclusion, ZnONPs can be further developed for pharmaceutical and industrial use.

“…Copper oxide nanoclusters (Cu x O) are a p-type semiconductor with high visible-light absorption and remarkable electrical properties [ 44 ]. Miyauchi et al [ 45 ] produced Cu x O (1 < x < 2) nanoclusters by combining Cu(I) and Cu(II) into and grafting them onto the surface of TiO 2 to obtain a Cu x O/TiO 2 photocatalyst, which presented high inactivation activity against bacteriophages under visible-light irradiation.…”

“…Fullerene can strongly absorb UV light and has a moderate absorption of visible light, and is thus expected as a new type of photocatalyst for disinfection. However, fullerenes are usually not used in their original form but are functionalized with different functional groups [ 44 ].…”

Infectious diseases caused by waterborne viruses have attracted researchers’ great attention. To ensure a safe water environment, it is important to advance water treatment and disinfection technology. Photocatalytic technology offers an efficient and practical approach for achieving this goal. This paper reviews the latest studies on visible-light composite catalysts for bacteriophage inactivation, with a main focus on three distinct categories: modified UV materials, direct visible-light materials and carbon-based materials. This review gives an insight into the progress in photocatalytic material development and offers a promising solution for bacteriophage inactivation.

“…However, some challenges still need to be overcome to ensure repeatability in the preparation of zinc oxide nanoparticles to enable the surface modification of these particles with organic compounds [20]. Also, zinc oxide may need to be combined with other material such as metals, semiconductors, and nanocarbons to overcome its limitations such as fast recombination of photogenerated electron-hole pairs, photocorrosion and need for UV light for activation in photocatalytic applications [72].…”

Zinc and its compounds, alloys and composites play an important role in the modern day world and find application in almost every aspect that can improve the quality of our lives. This ranges from supplements and pharmaceuticals that are meant to improve our health and wellbeing to additives meant to guard or reduce corrosion in metals. However, over the past several years, a new area of technology has been garnering a great deal of attention and has made use of zinc and its compounds. This is with reference to paper-based microfluidic technology that offers several advantages and that keeps expanding in the amount of applications it covers. In this paper, a review is offered for the applications that have used zinc or zinc compounds in paper-based microfluidic devices.
