摘要: 将飞秒激光聚焦于双金属甲苯离子前驱体溶液,在衬底上还原出可任意精细图案化的金银微纳结构.研究了不同比例离子前驱体溶液对加工的微纳结构中金银比例的影响.所得双金属微纳结构保留了金属材料的性质,在定点催化中表现出很好的催化效果.
英文摘要: Gold-silver( Au-Ag) alloy nanostructures were fabricated on substrate by the highly intense femtosecond laser pulses through a wet photochemical reduction without introducing additional reducing agent. The nanostructures can not only retain the characteristic of metallic materials,but also realize the assembling pattern of arbitrary subtle shape. The formation of Au-Ag alloy nanostructures was confirmed by energy dispersive X-ray( EDX) diffraction,indicating the fabricated nanostructures were different in the ratio of gold to silver for different molar ratios in the solution. The composite metal material was applied for catalysis of hydrogen peroxide and an ideal result was achieved.
