| 摘要 | Herein, MoO3 nanowires (Fe-MoO3 NWs) along the [110] direction were successfully synthesized in the presence of Fe3+ cations. The Fe-MoO3 NWs present a large specific surface area of 174.7 m(2) g(-1) and rich surface -OH groups, and the possible formation mechanism of such a structure is due to the adsorption of Fe3+ cations toward non-(110) planes of MoO3 in solution with pH greater than its isoelectric point. The obtained Fe-MoO3 NWs show excellent and highly selective adsorption capacity toward quasi-phenothiazine dyes (methylene blue, toluidine blue, azure I, and acridine orange). The dye removal rate could reach 99% in 3 min, and the maximum adsorption capacity is up to 144.3 mg g(-1) and the adsorption is up to 28.86 mg g(-1) per minute, which is 11 times greater than that of pure MoO3 and far greater than that of the recently reported MoO3 nanostructures. This excellent selective adsorption performance of Fe-MoO3 NWs was mainly attributed to the enhanced chemical adsorption of quasi-phenothiazine dyes by rich surface -OH groups and Fe species through hydrogen bond and coordination bond adsorption with N and S, respectively, which was confirmed by adsorption isotherms and adsorption kinetics. These results suggest the potential application of Fe-MoO3 NWs in the field of water pollution treatment. |
