Facile synthesis of Au/ZnO/RGO nanohybrids using 1,8-diamino-3,6-dioxaoctan as novel functional agent for photo-degradation water treatment

An ultra-low-cost and adjustable in-house electrospinning machine to produce PVA nanofiber

“…According to [14] , hydrothermal preparation was applied on Ag doping ZnO nanoparticles for semiconductor applications. Another research by [15] revealed that Au/ZnO/RGO nanohybrids using 1,8-diamino-3,6-dioxaoctan can be successfully prepared by hydrothermal as novel functional agent photo-degradation water treatment. In case of adsorbing heavy metals, a low-cost nano-powder adsorbent from the nature, beans peel, was succeeded to remove heavy metal Cd (II) from aqueous solution [16] .…”

“…14 containing four functional groups which include single bond area (4000–2500 cm −1 wavenumbers), triple bond area (2500–2000 cm −1 wavenumbers), double bond (2000–1500 cm −1 wavenumbers), and fingerprint area (<1500 cm −1 wavenumbers). The absorption peaks were clearly shown at 3296 cm −1 as O–H bonding resonance, 2940 cm −1 as CH 2 bonding resonance, 1720 cm −1 as C═O bonding resonance, 1425 cm −1 , 1322 cm −1 , 1247 cm −1 , 1090 cm −1 , 841 cm −1 , and 604 cm −1 as fingerprints resonances [13] , [14] , [15] . In this case, the product contains chemical PVA bonding free from impurities.…”

Structural studies of silica‐supported spinel magnesium ferrite nanorods for photocatalytic degradation of methyl orange

“…The complete degradation of methyl orange dye has been observed within 270 min by using MgFe 2 O 4 @ SiO 2 nanocomposite. The plausible mechanism [55,61] is as follows, Figure 9b depicts a kinetic plot of the methyl orange photo degradation reaction for various catalysts with respect to varying irradiation times. The control of experiments reveals that the concentration of methyl orange has been constant in the absence of photocatalysts in the presence of sunlight, suggesting that methyl orange dye is very stable photochemically.…”

“…[44] Muhammad Yakob [45] developed silica-supported magnesium ferrite nanomaterials that are nontoxic and biologically compatible with living organisms and are used as photocatalysts in the photocatalytic degradation of drugs [46] and methylene blue dyes. [47] The metal nanoparticles are used for photocatalytic degradation [48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63] and also for selective and aerobic oxidation of benzyl alcohol. [64,65] Herein, we report that the MgFe 2 O 4 @SiO 2 nanorods are synthesized by a simple co-precipitation method at room temperature.…”

Evaluation of the morphology and chelating agent excess in the design of luminescent metalorganic framework of europium thenoyltrifluoroacetone

“…There is a correlation between the coordination geometry and the dimensionality: size 1 Divisio ´n de Ciencias Ba ´sicas e Ingenierı ´a, Universidad Auto ´noma Metropolitana-Azcapotzalco, Col. Reynosa-Tamaulipas, Me ´xico or hardness of the metal center and electronic configuration affect the resulting topology of MOF. 2,3 Over the last years, MOFs have emerged as a new promising porous material in the areas of gas sorption and separation, 4 as platform for immobilizing molecular catalysts on conductive substrates, [5][6][7][8] water treatment, 9 storage, 10 antibacterial and antobiofilm 10 and light emitting diodes (LEDs). 11 Rare earth doped materials are very useful nowadays, because the characteristics that provide the lanthanides to the material can confer new applications as optoelectronics devices, fiber amplifiers, solid state laser, 12 solar cells, 13 and luminescence.…”
