摘　　要：以AgNO_(3)和无水Na_(2)CO_(3)为原料,以去离子水作为溶剂,利用共沉淀法合成了一种能吸收可见光的Ag_(2)CO_(3)半导体材料。借助傅里叶变换红外光谱(FT-IR)、紫外可见漫反射吸收光谱(UV-Vis DRS)、X射线衍射(XRD)等对Ag_(2)CO_(3)材料进行了表征分析。在模拟太阳光条件下研究了Ag_(2)CO_(3)材料对亚甲基蓝(MB)、罗丹明B(RhB)、甲基橙(MO)等常见有机染料的催化降解行为。结果表明所合成的Ag_(2)CO_(3)材料对亚甲基蓝(MB)、罗丹明B(RhB)、甲基橙(MO)等常见有机染料在60 min内其降解率分别达到了99.58%、95.51%、90.79%,是一种高效的可见光催化降解材料。Ag_(2)CO_(3)semiconductor material which could absorb visible light was synthesized using AgNO_(3)and anhydrous Na_(2)CO_(3)as raw materials and deionized water as solvent.Fourier transform infrared spectroscopy(FT-IR),UN-vis and X-ray diffraction(XRD)were used to characterize Ag_(2)CO_(3).The catalytic degradation performance of Ag_(2)CO_(3)for methyl blue(MB),rhodamine B(RhB),methyl orange(MO)and other common organic dyes was studied under simulated sunlight conditions.The results show that the degradation rate of Ag_(2)CO_(3)to methylene blue(MB),rhodesine B(RhB),methyl orange(MO)and other common organic dyes reached 99.58%,95.51%and 90.79%,respectively,within 60min.
