Evaluating the ability of separation and adsorption of SO2 by nano-CuO-Fe2O3/TiO2 in high concentrations and moderate temperatures

Adsorption of NOxwith NH3on γ-Al2O3and Its Effects on the Adsorption of As2O3Based on DFT

“…Liu et al developed novel microparticles consisting of Fe 3 O 4 and Fe 2 O 3 and found that, with the oxidation of SO 2 by O 2 , the conversion of Fe 3+ to Fe 2+ was accounted for the increment of arsenic adsorption capacity . Esfandiarpour et al synthesized nano-CuO-Fe 2 O 3 /TiO 2 particles as adsorbents and revealed that this kind of synthesized particles showed an excellent As 2 O 3 adsorption capacity even when the concentration of SO 2 was as high as 30,000 ppm . Abrahamsson et al explored NO x adsorption on the surfaces of ATiO 3 (A = Ca, Sr, and Ba) via DFT analysis and found out that NO adsorbed weakly on all facets, while NO 2 could selectively adsorb over AO-terminated surfaces strongly .…”
