Wool-coiled MoSrOS bimetal oxysulfide catalysts were synthesized by a simple method. The catalysts were characterized by different instruments. The MoSrOS reduction activities were also investigated by the reduction of Cr(VI), Rhodamine-B (RhB), Methyl orange (MO), Methylene blue (MB) and 4-nitrophenol (4-NP). The results showed that 100 mL (20 ppm) of 4-NP was completely reduced into 4-aminophenol (4-AP) in 20 min. Moreover, 100 mL (20 ppm) of MB, 100 mL (50 ppm) of RhB, 100 mL (50 ppm) of MO and 100 mL (50 ppm) of Cr(VI) were completely reduced within 6, 20, 40, and 30 min, respectively, by MoSrOS-2 bimetal oxysulfide catalyst. Hence, the wool-coiled MoSrOS bimetal oxysulfide catalysts could be used in the detoxification of toxic organic and inorganic pollutants.

用于催化还原有毒有机污染物和重金属离子的羊毛卷双金属氧硫化物 MoSrOS 催化剂合成
通过简单的方法合成了羊毛卷曲的MoSrOS双金属氧硫化物催化剂。催化剂用不同的仪器表征。还通过还原 Cr(VI)、若丹明-B (RhB)、甲基橙 (MO)、亚甲蓝 (MB) 和 4-硝基苯酚 (4-NP) 来研究 MoSrOS 的还原活性。结果表明,100 mL (20 ppm) 4-NP 在 20 分钟内完全还原为 4-氨基苯酚 (4-AP)。此外,100 mL (20 ppm) MB、100 mL (50 ppm) RhB、100 mL (50 ppm) MO 和 100 mL (50 ppm) Cr(VI) 在 6、20、40、和 30 分钟,分别由 MoSrOS-2 双金属氧硫化物催化剂。因此,羊毛卷状MoSrOS双金属氧硫化物催化剂可用于有毒有机和无机污染物的解毒。
