Green synthesis of Fe0 nanoparticles using Eucalyptus grandis leaf extract: Characterization and application for dye degradation by a (Photo)Fenton-like process

A facile in situ interfacial construction strategy of hierarchically distributed mixed-metal layered hydroxide/cellulose membranes towards efficient wastewater purification

“…Synchronously, the photo-Fenton performance of the catalytic membrane in multi-scenario environments was investigated by the degradation of organic pollutants under a solar simulator xenon lamp with an intensity of one sun (1 kW m −2 ). In more detail, the degradation efficiency was calculated using eqn (3): 11,17 where C 0 and C t are the initial concentration and the residual concentration at t of pollutants in the solar-driven water evaporation/photo-Fenton system, respectively.…”

“…Nevertheless, their metal-based hydroxides are still restricted to the nanoscale structure, which makes them easy to aggregate into clumps, thus leading to poor light utilization and recycling efficiency. 10,11 To overcome this shortcoming, some researchers employed loading strategies to enrich the hydroxides onto the polymer framework, thus realizing the uniform dispersion of nanoscale catalysts in the matrix. For instance, Choong et al 12 employed a co-precipitation method to load Mg-Fe LDHs onto polyacrylamide and polyvinyl alcohol frameworks, achieving an efficient removal of As(III) and As(V), and Hibino et al 13 prepared composite granules by incorporating Mg-Al layered double hydroxides into a polymeric gel, so as to remove the SO 4 2− ions in wastewater.…”

Synthesis of CoFe2O4 through Wet Ferritization Method Using an Aqueous Extract of Eucalyptus Leaves

“…Literature data mention that the IR spectra recorded for different types of eucalyptus extract revealed the functional groups which could be the responsible candidates for the obtained nanoparticles [28][29][30][31].…”

“…Previous studies revealed the use of eucalyptus extract, which is easy to obtain and sustainable, in the synthesis of metal nanoparticles such as Ag, Zn, Fe [25,27,28] and metal oxide TiO 2 , ZnO, La 2 O 3 [29][30][31]. These nanoparticles could be good candidates for biomedical, ecological, and agricultural applications.…”

Silver Nanoparticles for Waste Water Management

“…Extracellular methods have commonly been preferred to avoid the difficulty of extracting intracellular AgNPs for down-streaming processing. Biological methods are more environmentally friendly and cost-effective than physical/chemically synthesised methods [31,32]. AgNP characterisation has been used to analyse the properties, but the most basic characterisation method for qualitative analysis is to show the visualisation of colour changes [33].…”
