Through hydrogen reduction of metal precursors in supercritical CO2, Cu, and Pd, nanocrystals were deposited onto SiO2 nanowires to form different types of nanostructured materials, including nanocrystal-nanowire, spherical aggregation-nanowire, shell-nanowire composites, and "mesoporous" metals supported by the framework of nanowires. This supercritical fluid deposition technique is an attractive approach for modifying nanowires because of its generality and simplicity; the modified nanowires could be useful as catalysts and for further fabrication of multifunctional composites.
通过在超临界二氧化碳中对金属前驱体进行氢还原，将铜和钯纳米晶体沉积到二氧化硅纳米线上，以形成不同类型的纳米结构材料，包括纳米晶体 - 纳米线、球形聚集体 - 纳米线、壳 - 纳米线复合材料以及由纳米线框架支撑的“介孔”金属。这种超临界流体沉积技术因其通用性和简便性，是一种用于修饰纳米线的有吸引力的方法；修饰后的纳米线可用作催化剂以及进一步制造多功能复合材料。
