Abstract

This study involves the preparation and catalytic properties of anatase titanium dioxide nanofibers (TiO2 NFs) supported gold nanoparticles (Au NPs) using a model reaction based on the reduction of 4-nitrophenol (NP) into 4-aminophenol (AP) by sodium borohydride (NaBH4). The fabrication of surfactant-free Au NPs was performed using pulsed laser ablation in liquid (PLAL) technique. The TiO2 NFs were fabricated by a combination of electrospinning and calcination process using a solution containing poly(vinyl pyrolidone)(PVP) and titanium isopropoxide. The adsorption efficiency of laser-generated surfactant-free Au NPs to TiO2 NF supports as a function of pH was analyzed. Our results show that the electrostatic interaction mainly controls the adsorption of the nanoparticles. Au NPs/TiO2 NFs composite exhibited good catalytic activity for the reduction of 4-NP to 4-AP. The unique combination of these materials leads to the development of highly efficient catalysts. Our heterostructured nanocatalysts possibly form an efficient path to fabricate various metal NP/metal-oxide supported catalysts. Thus the applications of PLAL-noble metal NPs can widely broaden.

本研究以硼氢化钠（NaBH4）将 4-硝基苯酚（NP）还原成 4-氨基苯酚（AP）为模型反应，探讨了锐钛型二氧化钛纳米纤维（TiO2 NFs）支撑金纳米粒子（Au NPs）的制备和催化特性。利用液体脉冲激光烧蚀（PLAL）技术制备了不含表面活性剂的金纳米粒子。利用含有聚乙烯吡咯烷酮（PVP）和异丙醇氧化钛的溶液，结合电纺丝和煅烧工艺制备了 TiO2 NFs。分析了激光生成的不含表面活性剂的 Au NPs 在 TiO2 NF 支持物上的吸附效率与 pH 值的函数关系。结果表明，静电作用主要控制了纳米粒子的吸附。Au NPs/TiO2 NFs 复合材料在将 4-NP 还原成 4-AP 的过程中表现出良好的催化活性。这些材料的独特组合开发出了高效催化剂。我们的异质结构纳米催化剂可能是制造各种金属 NP/金属氧化物支撑催化剂的有效途径。因此，PLAL-贵金属 NPs 的应用范围将得到广泛拓宽。
