Developments of modified magnetic nanoparticle -supported heteropolyacid catalytic performances in dibenzothiophene desulfurization

Journal: Iranian Journal of Catalysis 2017

Abbas Teimouri, Hossein Salavati Shahnaz Kazemi,

In this research, Keggin-type polyoxometalate, H5PMoV2O40 (denoted as PMoV) was immobilized on modified NiFe2O4 nanoparticles to produce a magnetically separable catalyst. This catalyst was characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), cycli...

Methanol crossover and selectivity of nafion/heteropolyacid/montmorillonite nanocomposite proton exchange membranes for DMFC applications

Journal: Iranian Journal of Chemical Engineering 2017

M. Azimi, S.J. Peighambardoust,

In this work, we prepared the nafion/montmorillonite/heteropolyacid nanocomposite membranes for direct methanol fuel cells (DMFCs). The analyses such as X-ray diffraction (XRD), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM) were conducted to characterize the filler dispersion and membrane structure in prepared nanocomposite membranes. XRD patterns of nafion-CsPW-MMT ...
