“…Investigation of Figure a demonstrates that the catalytic reduction of RhB was proceeded successfully and completed in 230 sec. Indeed, the NaBH 4 alone had a little effect on the decolorization and absorbance band of RhB (Figure b) . This result indicated that MgBC displayed a key role in the reduction RhB.…”

The present paper describes the preparation of magnetic hollow biocomposites (MgBC) from Lycopodium clavatum (LC) pollens by using microwave chemistry and investigates their catalytic activities on the model reaction of Rhodamine B (RhB), which is a representative environmental organic pollutant, in the presence sodium borohydride. The fabricated MgBC displayed unique microstructure with a narrow size distribution of 28±0.45 μm and surface, which was decorated with reticulate web‐like micro ridges surrounded by pores and Fe3O4 nanoparticles (a spherical form with an average size of about 8.54±2.74 nm). The produced MgBCs exhibited high efficiency and excellent catalytic reduction performance for RhB (100 % removed within 230 sec), which could be ascribed to unique structure and high surface area of the Fe3O4 doped bio‐composite. Furthermore, the MgBCs recycled five times using an external magnet without a major loss of catalytic efficiency. Therefore, MgBC can be used as effective and suitable recycled catalysts for practical applications.

“…Some of these synthetic methods may have some drawbacks, namely the use of potentially hazardous reducing/capping agents (e.g., hydrazine and poly- N -vinylpyrrolidone) and toxic solvents. Additionally, the conventional physicochemical procedures entail time consuming, expensive/special equipment requiring high energy, pressure, and temperature, culminating in the formation of toxic byproducts/wastes and hazardous materials [ 6 , 43 , 44 ]. Therefore, the design of greener and sustainable synthetic routes is preferred since they are safe, environmentally salubrious, and often cost-effective [ 45 , 46 , 47 , 48 , 49 ].…”

Nanoparticles (NPs) and multifunctional nano-sized materials have significant applications in diverse fields, namely catalysis, sensors, optics, solar energy conversion, cancer therapy/diagnosis, and bioimaging. Trimetallic NPs have found unique catalytic, active food packaging, biomedical, antimicrobial, and sensing applications; they preserve an ever-superior level of catalytic activities and selectivity compared to monometallic and bimetallic nanomaterials. Due to these important applications, a variety of preparation routes, including hydrothermal, microemulsion, selective catalytic reduction, co-precipitation, and microwave-assisted methodologies have been reported for the syntheses of these nanomaterials. As the fabrication of nanomaterials using physicochemical methods often have hazardous and toxic impacts on the environment, there is a vital need to design innovative and well-organized eco-friendly, sustainable, and greener synthetic protocols for their assembly, by applying safer, renewable, and inexpensive materials. In this review, noteworthy recent advancements relating to the applications of trimetallic NPs and nanocomposites comprising these NPs are underscored as well as their eco-friendly and sustainable synthetic preparative options.

View full text Add to dashboard Cite

Recent developments in nanotechnology has increased the market value of nanoproducts in various industries. This has increased concerns associated with potential toxicity of nanoproducts to humans and the environments. Even though, green and biosynthesized nanoparticles are considered to be less toxic than chemically synthesized nanoparticles, they still possess some level of toxicity. Conventional toxicity assessments via human cells, live animals such as rat, frog or rabbit have several drawbacks including ethical issue and challenges involving the maintenance and development of cell cultures. Zebrafish (Danio rerio) is a transparent vertebrate fish that can reproduce rapidly. Its larvae develop in 5 days up to 3-5 cm long. It also possesses about 69% similar genetic profile, molecular mechanism, cell development and organ physiology as humans. Hence, it has the potential to be utilized as an alternative to humans or live animal models for initial drug screening and toxicity tests. European Union, USFDA and ICH have approved the use of zebrafish for toxicological evaluation of pharmaceutical products including nanomedicines. The article presents for the potential of zebrafish in preclinical evaluation of the toxicity of nanomaterials. It also discusses other potential applications, including medical imaging and environmental toxicity.
