离子液体调控合成AuPd纳米刺球及其催化性能
|
摘要
在室温水溶液中,采用离子液体[C_4im]Cl调控合成了AuPd纳米刺球。采用多种表征技术对产品的形貌和结构进行了分析。研究结果表明:所制备的AuPd纳米刺球由0.5～1.0μm的球形颗粒组成。颗粒表面较为粗糙,有许多纳米级颗粒组成的尖刺,具有明显的微纳分级结构。同时,AuPd刺球在有机染料亚甲基蓝的降解过程中表现出良好的催化活性,整个反应过程仅需150 s,反应速率常数为0.017 4 s~(-1),其催化活性是商用Pd/C催化剂的1.67倍。
The Au Pd nano-acanthospheres were controllably synthesized by the modulation of an ionic liquid[C_4 im]Cl in aqueous solution at room temperature. A variety of techniques were used to characterize and analyze the morphology and structures of the product. The results show that the prepared AuPd nanoacanthospheres are composed of spherical particles of 0. 5 ～ 1. 0 μm. The surface of the product is relatively rough,and there are many spikes composed of nanometer-sized particles with obvious micro-nano hierarchical structures. At the same time,the prepared Au Pd nano-acanthospheres show excellent catalytic activity for the degradation of organic dye methylene blue. The reaction is completely finished within only 150 s and the reaction rate constant is 0.017 4 s~(-1),which is 1.67 times higher than that of commercial Pd/C catalyst.
