“…The reusability was evaluated for the best catalyst, being excellent as it showed a degradation of 92.98% in the third cycle. The preparation of ZnAl-chloride hydrotalcite (Zn/Al = 2) and its interaction with the antibiotics tetracycline and oxytetracycline was considered by Bouaziz et al (2018).…”

Nano-Materials as Photocatalysts for Degradation of Environmental Pollutants

View full text Add to dashboard Cite

The presence of pharmaceutical compounds in natural water is an increasing problem as these compounds have environmental effects even at low concentrations. Adsorption has been largely used for the removal of pollutants, in the last years advanced oxidation processes (AOPs) have gained attention, as they may lead to the complete degradation of the pollutants. Several solids have been used as photocatalysts, from TiO2, by far the most used, to some families of other materials. In the present chapter, a review on the use of hydrotalcite-like compounds, also known as Layered Double Hydroxides (LDHs), as catalysts for the photodegradation of pharmaceutical pollutants is presented.

“…A different scenario has been elicited as it concerns antibiotics loading. Model antibiotics such as tetracycline and oxytetracyline [239] were shown not to be intercalated into LDHs, but more likely to be adsorbed on their external surface and released according to a Fickian diffusion model. The LDHs adsorbed antibiotics are still active towards E. coli and S. epidermis, showing a decrease of efficacy in comparison to the free molecules.…”

Layered double hydroxides (LDHs) are an emergent class of biocompatible inorganic lamellar nanomaterials that have attracted significant research interest owing to their high surface-to-volume ratio, the capability to accumulate specific molecules, and the timely release to targets. Their unique properties have been employed for applications in organic catalysis, photocatalysis, sensors, drug delivery, and cell biology. Given the widespread contemporary interest in these topics, time-to-time it urges to review the recent progresses. This review aims to summarize the most recent cutting-edge reports appearing in the last years. It firstly focuses on the application of LDHs as catalysts in relevant chemical reactions and as photocatalysts for organic molecule degradation, water splitting reaction, CO2 conversion, and reduction. Subsequently, the emerging role of these materials in biological applications is discussed, specifically focusing on their use as biosensors, DNA, RNA, and drug delivery, finally elucidating their suitability as contrast agents and for cellular differentiation. Concluding remarks and future prospects deal with future applications of LDHs, encouraging researches in better understanding the fundamental mechanisms involved in catalytic and photocatalytic processes, and the molecular pathways that are activated by the interaction of LDHs with cells in terms of both uptake mechanisms and nanotoxicology effects.

“…The idea behind their synthesis is to use the combination of two different nanomaterials within the nanometer range for designing new materials, with unprecedented flexibility and improved chemical as well as physical properties. The nanocomposites have shown potential applications in various fields like catalysis, [4][5][6] biosensors, [7][8][9] energy storage, [10][11][12] antibacterial, [13][14][15] etc. due to their distinctive optical, mechanical, thermal, and electrical properties.…”

Efficient Degradation of Methylene Blue Dye and Antibacterial Performance of Shape Controlled RuO₂ Nanocomposites

et al. 2021

Arising global health problems have drawn significant interest in the researcher's community to fabricate multifunctional nanocomposites that could directly or indirectly treat polluted water. Herein, a simple but cost‐effective method is proposed for the fabrication of flower‐shaped RuO2 NPs (nanoparticles) on SWCNTs (single‐walled carbon nanotubes). The synthesized composite acts as a one‐stop solution for eliminating harmful dyes and pathogens from potable water. The structural, morphological, and chemical compositions of RuO2/SWCNT were carefully investigated and the observations revealed that crystalline RuO2 NPs possessing quantum dot range sizes were homogeneously decorated on the inner as well as exterior cavities of activated SWCNTs. The nanocomposite proved as an efficient photocatalyst against MB (methylene blue) dye and colourless phenol. The photocatalytic degradation efficiencies of RuO2, SWCNT, and RuO2/SWCNT is 57%, 21%, and 92.6% respectively against MB dye. Colourless phenol degradation and scavenging studies were performed to rule out the photosensitization effect and examine the role of active species during photodegradation respectively. Moreover, when the residual remains of the composite after degradation experiments were used as an antibacterial agent, it proved most lethal against E. coli and L. monocytogenes with 13.7±0.45 and 12.5±0.15 mm diameter of ZOI respectively at rather low doses (0.07 mg/mL). Finally, the synthesized composite could reduce the industrial cost of application and also influence the engineering and logical fabrication of nanocomposites for their reusability and multifunctional proficiencies.
