Agricultural waste biomass-assisted nanostructures: Synthesis and application

Abstract

Metal oxide nanoporous materials and nanoparticles have main potential uses in several different fields such as nanoelectronics, biomedical science, renewable solar energy, drug-gene delivery, thermal insulation, and so on. On the other hand, it is vital for scientists to understand that agricultural waste biomass-assisted synthesis is less costly, environmentally friendly and renewable strategy, and therefore, agricultural wastes are ideal renewable resources for production of nanostructures as a substitute for toxic chemicals. This present review includes significant recent improvements concerning the synthesis of agricultural waste biomass-assisted metal oxide nanostructures and their application. The goal is to provide a vision for the use of non-extracted agricultural waste, especially lignocellulosic biomass an inexpensive, green, differentiated resource and policy for the synthesis of valuable nanoporous materials and nanoparticles.

Synthesis of Silver Nanoparticles Using Orange Peel Extract Prepared by Plasmochemical Extraction Method and Degradation of Methylene Blue under Solar Irradiation

“…As it can be seen, as the concentration of silver nitrate changes from 0.25 to 0.5 mmol/L, the intensity of the surface plasmon resonance (SPR) peak increases remarkably and the location of SPR peak. e increase in intensity suggests that more nanoparticles are formed [1][2][3][4][5][6][7][8][9][10][11][12][13][14][26][27][28].…”

“…It is known that the "green" synthesis of nanoparticles is based on the use of reducing agents present in the composition of biomaterials [7][8][9][10][11][12][13]. ese substances are characterized by their redox potential and are able to recover Advances in Materials Science and Engineering 5 cations of the dissociated metal salts.…”

“…Recently, as a further step towards the development of greener and more sustainable processes, attempts have been made to replace plant parts with agroindustrial wastes [9]. Overall, the use of agroindustrial wastes for the eco-friendly production of nanoparticles seems to be promising, but relatively few studies conducted on this topic make it difficult to draw definitive conclusions [10].…”

“…However, an analysis of the pertinent literature revealed actual issues and shortcomings limiting the advancement of green synthesis [1][2][3][4][5][6][7][8][9][10][11][12][13]. Significant issues have been associated with the source/type and concentration of plant extracts and waste materials.…”

Green synthesized titanium dioxide nanoparticles and their future applications in biomedicine, agriculture and industry

“…In the case of TiO 2 NPs, the precursor can be represented by titanium tetraisopropoxide (Landage et al, 2020), metatitanic acid (Alavi and Karimi, 2018), titanium oxysulfate (Subhapriya and Gomathipriya, 2018) or bulk forms of TiO 2 (He et al, 2017). If we go further, agrowastes or organic matter waste may represent a sustainable source of biomolecules for the green synthesis of NPs (Zamani et al, 2019). However, biological techniques remained at a laboratory scale mostly because the morphology of NPs is hard to be controlled.…”
