Influence of hydrothermal synthesis conditions on size, morphology and colloidal properties of Hematite nanoparticles

Effect of Morphologically Controlled Hematite Nanoparticles on the Properties of Fly Ash Blended Cement

“…Summarized results of crystal size and particle size are shown for comparison in Figure 4 . Results confirmed that surfactants significantly influence the shape and size of the nanoparticles, in accord with the findings of Jing et al [ 33 ] and Colombo et al [ 34 ].…”

“…However, it was reported that during the hydrothermal synthesis, hydrolysis of DMF leads to an acidic solution [39]. The acidic environment put a limit to particle size during nanoparticle synthesis [40], which is key for monodispersive nanocube formation. Furthermore, undercoordinated surface Fe atoms will lead more acidic point of zero charge for hematite surfaces [41],…”

Synthesis and Applications of Hematite α-Fe2O3 : a Review

“…These nanostructures are benefitting various applications because of their unique structural, optical, and electrical behaviors. The α-Fe2O3 nanostructures are nanorod arrays, as shown in Figure 1 [6], hematite-shaped flowers, micro cubes [7], nanowires [8], nanotubes [9], nanoflakes [10], [11], nanoparticles [12], [2], and nanorod arrays [13], [14]. The applications of its nanostructure reach many utilities such as electrochemical photo water separation, gas sensors, photocatalytic, and lithium-ion batteries.…”

“…Particle size increases with reaction time. The reaction time of more than 6 hours gives the maximum particle size at acidic pH, which provides a better condition for growth step with the dehydration process [12]. Other researchers also carried out a similar method where Zn+ controlled the formation of α-Fe2O3 microcubes with a constant diameter of 250 nm, and the morphological results showed regular structure [15].…”
