“…23 Due to its unique physical and chemical properties, hematite has many advantages such as nontoxicity, abundance, inexpensiveness and stability, and hence has been studied in wide variety of applications. [24][25][26][27][28][29][30][31] For oil and gas applications, recent studies have shown that hematite can be used as a highly active heterogeneous catalyst in the catalytic steam hydrocracking of petroleum residual oil. [32][33][34] In this paper, the application of hematite nanoparticles as catalyst in aquathermolysis was studied.…”

The potential usage of hematite nanoparticles as heterogeneous catalysts in aquathermolysis was investigated in this work. The desulfurization of thiophene was studied to investigate the catalytic activity of hematite in the aquathermolysis of heavy oil. It was found that reaction conditions, e.g., reaction time and temperature, ratio between thiophene and water, hematite nanoparticle size, catalyst concentration, and the presence of hydrogen donors, influenced the ability of hematite nanoparticles to decompose thiophene. Experimental results showed that thiophene conversion was increased with reaction time, temperature and catalyst concentration but decreased with thiophene/water ratio and particle size. Further analysis showed that the activity of the hematite nanocatalyst was also reduced in the presence of hydrogen donors. This is because hydrogen donors occupy the catalyst surface and block the catalytic sites. Furthermore, FTIR and XRD analyses revealed that thiophene underwent oxidative

“…Recent applications of magnetic NTs have mainly been focused in the biological field. Chen et al (2010Chen et al ( , 2011cChen et al ( , 2012b demonstrated drug loading and releasing capabilities of hematite, maghemite, and magnetite NTs fabricated using a template-assisted method combined with hydrothermal synthesis, as well as their biocompatibility. Magnetic NTs formed by magnetite NPs embedded in silica NTs were reported by Son et al (2005Son et al ( , 2006 as powerful imaging nanostructures for MRI and to track drug delivery controlled by an external magnetic field and hence directed to specific anatomical sites in vivo (Mitchell et al, 2002).…”

“…Other authors also demonstrated the synthesis and characterization of magnetic NTs as novel tunable MRI contrast agents (Bai et al, 2008;Zabow et al, 2009). The effects of magnetic NTs on the growth of cultured neurons were tested, and preliminary results showed promising applications of these nanostructures in the treatment of diseases in the nervous system (Chen et al, 2006(Chen et al, , 2012bXie et al, 2010Xie et al, , 2011. NTs of other materials like Fe 70 Pd 30 obtained by electrodeposition in porous templates were also functionalized and tested in drug-release assays (Rozman et al, 2012).…”
