Adsorption of Cd²⁺ions on plant mediated SnO₂nanoparticles

Green synthesis and characterization of tin dioxide nanoparticles for photocatalytic and antimicrobial studies

“…All these diffraction bands are found similar with the peaks listed in JCPDS card 01-077-0450 attributed to the tetragonal crystal system of SnO 2 NPs. The crystallite size calculated by Debye Scherer's equation is 15.63 nm, whereas, 1.16% imperfection was found in the crystal (Haq et al 2016).…”

“…Numerous procedures have been reported for the synthesis of SnO 2 NPs including sol-gel, hydrothermal, co-precipitation, solvothermal, chemical vapor deposition and carbothermal reduction process (Leite et al 2002, Fujihara et al 2004, Liu et al 2005, Qiao et al 2014, Bhagwat et al 2015, Nadaf and Venkatesh 2016. However, the use of plant materials for the synthesis of nanomaterials is more advantageous due to its easy handling, environment friendly and economical nature (Haq et al 2016).…”

Enzyme production ofd-gluconic acid and glucose oxidase: successful tales of cascade reactions

“…19,38 Among the Aspergillus species, remarkable attention has been given to A. niger over the last 60 years. [46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65] Despite the great success of glucose oxidase production from Aspergillus and Penicillium species, efforts to find other glucose oxidase sources are being developed, including other glucose oxidaseproducing fungi, e.g., Cladosporium neopsychrotolerans 66 and Mucor circinelloides; 67 other Aspergillus species, e.g., A. tubingensis, 29 A. terreus, 68 A. oryzae, 69 A. carbonarius, 70 and A. nidulans; 71 and some glucose oxidase-producing bacteria. 72 The demand for glucose oxidase is increasing due to its growing applications in different industrial sectors.…”

“…The recombinant Y. lipolytica strain produced up to 280 and 145 U L −1 of extracellular and intracellular glucose oxidase, respectively, from A. niger after 7 days in YPD medium. In other approaches, mutagenesis of A. niger by UV irradiation 47 and chemical mutagens 83 generated mutated strains that produced around two-fold and threefold more glucose oxidase than their parental wild strains, respectively.…”

Europium doping effect on 3D flower-like SnO2 nanostructures: morphological changes, photocatalytic performance and fluorescence detection of heavy metal ion contamination in drinking water

“…Among them tin oxide (SnO 2 ), an n-type semiconductor with a wide direct band-gap (3.6 eV), has attracted extensive attraction due to its wide potential applications in photocatalysis, 8 photodetectors, 9 gas sensors, 10 rechargeable batteries 11 and heavy metal ion detection. 12 Usually, the morphologies of nanosized metal oxide materials have an effect on their applications. 13 Therefore, it is important to construct well controlled morphologies which possess high surface to volume ratio and have good performance and high reactivity.…”
