Recently, novel morphological nanocomposites have attracted increasing attention due to their unique features. In this work, a 3D hierarchical magnetic Fe@Pt/Ti(OH)(4) nanoarchitecture has been synthesized successfully. TEM images were used to confirm the success of each of the synthesis steps, and the reduction of 4-NP to 4-AP was employed to evaluate their catalytic performance. Their large surface area and nanorod structure guarantee their good catalytic performance. Furthermore, the as-prepared nanocapsule shows excellent anti-sintering properties for the physical barrier effects of Ti(OH)(4) nanorods. The sample calcined at 700 degrees C showed the highest catalytic activity in our work due to the decomposition of Ti(OH)(4). Finally, the synthesized Fe@Pt/Ti(OH)(4) nanocomposite could be easily recycled.
