One pot solution combustion synthesis of highly mesoporous hematite for photocatalysis

Utilization of Iron Ore Tailing for the Preparation of ?-Fe2O3 nanoparticles

“…The band gap energy was calculated according to the Tauc's equation (αhν) 1/n =A(hν-E g ), where, α is the absorption coefficient, hν is the incident photon energy, A is a constant, E g is the band gap energy and n is the exponent (n=2 or 1/2 for indirect or direct transition). The intercept of the straight line at (αhν) 2 =0 in the plot (αhν) 2 versus hν (Fig.5 inset), gave the value of E g correspondence to 2.03 eV, which was consistent with the reported value (E g =1.9-2.2 eV) [13] .…”

Magnetic iron nanoparticles prepared by solution combustion synthesis and hydrogen reduction

“…In view of these advantages, a large number of efforts have been made to prepare iron oxides by SCS [24][25][26][27]. Despite of such fascinating research results, to our knowledge, no research on hydrogen reduction of iron oxides by SCS has been reported.…”

Review of Recent Studies on Solution Combustion Synthesis of Nanostructured Catalysts

“…The SCS synthesized hematite was tailored by the suitable fuel to oxidizer ratio ( Φ = 0.3) and found to possess a highly mesoporous structure with specific surface area of 103 m 2 g −1 and an average size of about 20 nm. Its photocatalytic activity was evaluated toward the degradation of the methylene blue pollutant in water at ambient temperature and it was ascertained that the synthesized mesoporous hematite could be a favorable visible light photocatalyst for organics decomposition …”
