摘要

采用一锅自燃烧法成功合成了掺杂Mn2+的ZnFe2O4纳米晶体。采用XRD、FT-IR、HR-SEM、TEM、EDX、BET、DRS、PL和VSM对合成的MnxZn1-xFe2O4纳米晶体进行了表征。结果表明:制备的尖晶石MnxZn1-xFe2O4纳米晶体结晶度高，尺寸分布均匀，形貌呈颗粒状;本研究结果表明，TiO2的加入增强了MnxZn1-xFe2O4的光催化活性。在确定尖晶石MnxZn1-xFe2O4具有光催化活性后，还对MnxZn1-xFe2O4 -TiO2混合氧化物催化剂进行了光催化降解4-氯酚的测试。

Magnetically Separable MnxZn1-xFe2O4; (0.0 ≤ x ≤ 0.5) Nanostructures: Structural, Morphological, Opto-Magnetic, and Photocatalytic Properties

Mn2+ doped ZnFe2O4 nanocrystals have been successfully synthesized by one-pot autocombustion method. The synthesized MnxZn1-xFe2O4 nanocrystals were characterized by XRD, FT-IR, HR-SEM, TEM, EDX, BET, DRS, PL, and VSM. The results indicated that the prepared spinel MnxZn1-xFe2O4 nanocrystals showed high crystallinity and uniform size distribution with particle-like morphologies. The present study leads to enhance the photocatalytic activity of MnxZn1-xFe2O4 with the addition of TiO2. Having established that spinel MnxZn1-xFe2O4 was photocatalytically active, the mixed oxide catalysts of MnxZn1-xFe2O4 -TiO2 were also tested for the photocatalytic degradation of 4-chlorophenol.
