In the alpha-FeOOH/gamma-Fe2O3 photo-Fenton process,gamma-Fe2O3 could act as an electron trap and inhibit the reaction between photogenerated electrons and H2O2. Consequently, the production of HO center dot was reduced, whereas more holes were separated and the production of center dot O-...
Besides, in gamma-Fe2O3/alpha-MnO2/PS reaction system, about 92.79% of Rhodamine B could be removed within 30 min. The result proves that when the gamma-Fe2O3 content is 12.5%, gamma-Fe2O3/alpha-MnO2 nanocomposite exhibits superior activation performance. gamma-Fe2O3/alpha-MnO2/PS ...
The alpha-Fe2O3 changes to Fe3O4 during sodium extraction, while the gamma-Fe2O3 remains unaltered upon cycling. The gamma-Fe2O3 shows high electrochemical performance regarding cycle life and discharge capacity than alpha-Fe2O3 (considering up to 80 cycles). The discharge capacity of ...
This work reports on Fe2O3 and ZnO materials for lactate quantification. In the synthesis, the bi-phase γ-/α-Fe2O3 and γ-/α-Fe2O3/ZnO nanoparticles (NPs) were obtained for their application in a lactate colorimetric sensor. The crystalline phases of

CuO/alpha-Fe2O3/gamma-Al2O3 exhibited superior photocatalytic efficacy as compared to CuO/gamma-Al(2)O(3 )and alpha-Fe2O3/gamma-Al2O3 binary and pure oxides of gamma-Al2O3, CuO and alpha-Fe2O3. The marvelous photocatalytic activity of CuO/alpha-Fe2O3/gamma-Al2O3 ternary ...
Especially, the porous alpha-gamma Fe2O3 nanotubes produced by two-step AB MLD from iron tert-butoxide and ethylene glycol exhibit the highest photocatalytic activity, which is more than a 6.5-fold and 20-fold improvement compared with the nonporous pure alpha-Fe2O3 nanotubes and commercial ...
