We report a facile synthesis of MXene/bismuth ferrite (TiCT @ BiFeO) nanocomposites using hydrazine hydrate induced with the hydrothermal method. Preparation of the composite with hydrazine hydrate prevents the formation of BiFeO inside the matrix. The 25 wt % loading of BiFeO acts as spacers for the multilayer restacking of MXene flakes by retaining the (002) plane. This promotes large dc conductivity with interfacial and defect dipole polarization mechanisms inside the composite material. The thinner M-H loop also indicates the minimal magnetic loss inside the composites. The facile synthesis strategy provides outstanding properties in TiCT @ BiFeO composites as two-dimensional multiferroic materials.
我们报道了一种使用水合肼诱导水热法简便合成MXene/铋铁氧体(TiCT@BiFeO)纳米复合材料的方法。用水合肼制备复合材料可防止基体内部形成BiFeO。25 wt%负载的BiFeO通过保留(002)面作为MXene薄片多层重新堆叠的间隔物。这通过复合材料内部的界面和缺陷偶极极化机制促进了大的直流电导率。更薄的M-H回线也表明复合材料内部的磁损耗最小。这种简便的合成策略为作为二维多铁性材料的TiCT@BiFeO复合材料提供了优异的性能。
