Synthesis of Iron Oxide Nanoparticles using Borohydride Reduction
Iron oxide (Fe2O3) nanoparticles were synthesized by a simple approach using sodium borohydride (NaBH4) and Iron chloride hexahydrate (FeCl3.6H2O). Their physicochemical properties were characterized by high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and electron dispersive spectroscopy (EDS). XRD pattern showed that the iron...

متن کاملEnzymatic reduction of iron oxide by fungi.
The occurrence of the iron-reducing phenomenon among some common fungi was studied. Results indicated that (i) the reduction of ferric iron to the ferrous state by fungi seems to be restricted to nitrate reductase-inducible strains such as Actinomucor repens, Alternaria tenuis, Fusarium oxysporum, and F. solani and (ii) the amount of dissolved ferrous iron may be reduced progressively by increa...
متن کاملNanosized iron oxide colloids strongly enhance microbial iron reduction.
Microbial iron reduction is considered to be a significant subsurface process. The rate-limiting bioavailability of the insoluble iron oxyhydroxides, however, is a topic for debate. Surface area and mineral structure are recognized as crucial parameters for microbial reduction rates of bulk, macroaggregate iron minerals. However, a significant fraction of iron oxide minerals in the subsurface i...
