Preparation and spectral characterization of nanoFe. TEM images of nanoFe prepared by the reduction of FeSO4·7H2O using NaBH4 in 0.5% CMC solution. A, B NanoFe in reaction mixture solution. C, D NanoFe redispersed in 0.5% CMC solution after magnetic separation under ultrasound. E Powder XRD spectrum, F Raman spectra, G XPS Survey spectrum, and H Fe 2p3/2 and 2p1/2 spectrum of nanoFe. I Hydrogen bubbles were produced by weak hydrolysis of nanoFe in anaerobic water. J Photograph of the samples: a nanoFe in reaction mixture solution, b nanoFe in water after magnetic separation, c nanoFe redispersed in 0.5% CMC solution after magnetic separation under ultrasound
