Sol-gel and precipitation reaction methods were used to synthesize Un-doped and Fe-doped SnO/CoO nanocomposites under UV light; the synthesized nanocomposites were applied for the photocatalytic degradation of metronidazole antibiotic. The developed photo catalyst was well characterized using energy dispersive X-ray spectrometer (EDX), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), field emission scanning electron microscopy (FE-SEM), UV-Visible and photoluminescence (PL) spectroscopy. Effective parameters such as pH, photocatalyst dose and contact time was optimized and well investigated. From the obtained facts it is clear that the 98.3% of MTZ was degraded with in 15min, pH6 and 0.1g catalyst when the Fe molar ratio was 1:1 at %. As compared to results obtained from un-doped SnO/CoO nanocomposites Fe doped SnO/CoO nanocomposites possess greater photocatalytic efficiency.
采用溶胶 - 凝胶法和沉淀反应法在紫外光下合成了未掺杂和铁掺杂的SnO/CoO纳米复合材料；将合成的纳米复合材料用于甲硝唑抗生素的光催化降解。利用能量色散X射线光谱仪（EDX）、X射线衍射（XRD）、振动样品磁强计（VSM）、场发射扫描电子显微镜（FE-SEM）、紫外 - 可见光谱和光致发光（PL）光谱对所制备的光催化剂进行了充分表征。对诸如pH值、光催化剂剂量和接触时间等有效参数进行了优化并深入研究。从所得结果可以清楚地看出，当铁的摩尔比为1:1%时，在pH6、0.1g催化剂的条件下，15分钟内98.3%的甲硝唑被降解。与未掺杂的SnO/CoO纳米复合材料的结果相比，铁掺杂的SnO/CoO纳米复合材料具有更高的光催化效率。
