摘要
利用室温液相还原法和低温水热法制备了立方状和球状氧化亚铜,通过X射线衍射、场发射扫描电子显微镜对合成产物进行了表征。以合成产物光催化降解偶氮染料甲基橙为模型,研究了不同形貌Cu2O的光催化性能,结果表明,球状氧化亚铜对甲基橙的脱色率达89.0%,球状氧化亚铜/Fenton复合体系中甲基橙的脱色率达98.2%。初步探讨了Cu2O粉体催化降解甲基橙的过程和机理。
Cu2O microcubes and nanospheres were prepared by solution-phase reducing method and hydrothermal treatment,respectively.The products were characterized via X-ray diffraction（XRD） and field emitted scanning electron microscopy（FESEM）.The photocatalytic activities of as-synthesized Cu2O microcubes and nanospheres toward methyl orange were studied.The decoloration rates of methyl orange in assynthesized Cu2O microcubes and nanospheres system was 77.4% and 89.0%,respectively.In the Cu2 O/Fenton composite system,the decoloration rate of methyl orange could reach 98.2%.In addition,a proposed photocatalytic degradation mechanism of Cu2O for methyl orange was provided.
