| 摘 要： | 在表面活性剂PEG-400的存在下,通过室温下充分研磨K4P2O7·3H2O和Fe2(SO4)3的混合物使其进行固态反应,研磨结束后将反应混合物在60℃下保温4 h。然后用去离子水洗去混合物中的可溶性无机盐,最后在90℃下烘干,即得纳米晶KFeP2O7的前驱体。将前驱体煅烧可得到纳米晶KFeP2O7。煅烧产物通过X-射线粉末衍射(XRD)、傅里叶变换红外光谱(FT-IR)、扫描电子显微镜(SEM)和紫外-可见光谱(UV-vis)表征。结果表明,在750℃下煅烧2 h得到的产物为单斜晶系KFeP2O7。紫外-可见光谱分析显示,单斜KFeP2O7对紫外光具有强的吸收能力。 |

| Abstract: | The precursor of nanocrystalline KFeP2O7 was obtained by grinding fully K4P2O7·3H2O and Fe2(SO4)3 at room temperature in the presence of surfactant polyethylene glycol(PEG)-400,maintaining the mixture at 60 ℃ for 4 h,and then washing the mixture with deionized water to remove soluble inorganic salts,and at last drying at 90 ℃.The nanocrystalline KFeP2O7 was obtained by calcining the precursor.The calcined products were characterized using XRD,FTIR,SEM,and UV-vis spectra.The data showed that the calcined product obtained at 750 ℃ for 2 h was KFeP2O7 with monoclinic structure.The analysis of UV-vis showed that monoclinic KFeP2O7 had a strong absorption of ultraviolet light. |
