Aqueous chemical synthesis of iron oxides magnetic nanoparticles of different morphology and mesostructure

The influence of H2O or/and O2 introduction during the low-temperature gas-phase sulfation of organic COS + CS2 on the conversion and deposition of sulfur-containing species in the sulfated CeO2-OS catalyst for NH3-SCR

“…According to IUPAC classification, the assynthesized catalysts exhibit type IV isotherms of N 2 adsorption-desorption, and the related capillary-condensation hysteresis loop corresponds to the H3 type, which is usually attributed to the pores formed from the accumulation of nanoparticles. 4,42 This is consistent with the results of SEM and TEM.…”
