One-step hydrothermal synthesis of Sn-doped α-Fe2O3 nanoparticles for enhanced photocatalytic degradation of Congo red
文献摘要：
We report on the synthesis of Sn-doped hematite nanoparticles(Sn-α-Fe2O3 NPs)by the hydrothermal method.The prepared Sn-α-Fe2O3 NPs had a highly pure and well crystalline rhombohedral phase with an average particle size of 41.4 nm.The optical properties of as-synthesized α-Fe2O3 NPs show a higher bandgap energy(2.40-2.57 eV)than that of pure bulk α-Fe2O3(2.1 eV).By doping Sn into α-Fe2O3 NPs,the Sn-doped hematite was observed a redshift toward a long wavelength with in-creasing Sn concentration from 0％to 4.0％.The photocatalytic activity of Sn-doped α-Fe2O3 NPs was evaluated by Congo red(CR)dye degradation.The degradation efficiency of CR dye using Sn-α-Fe2O3 NPs catalyst is higher than that of pure α-Fe2O3 NPs.The highest degradation efficiency of CR dye was 97.8％using 2.5％Sn-doped α-Fe2O3 NPs catalyst under visible-light irradi-ation.These results suggest that the synthesized Sn-doped α-Fe2O3 nanoparticles might be a suitable approach to develop a photocatalytic degradation of toxic inorganic dye in wastewater.
