    • Nano-catalysts that have utility for forming nanostructures and manufacturing nanomaterials are described. In some embodiments the nano-catalyst is formed from a powder-based substrate material and is some embodiments the nano-catalyst is formed from a solid-based substrate material. In some embodiments the substrate material may include metal, ceramic, or silicon or another metalloid. The nano-catalysts typically have metal nanoparticles disposed adjacent the surface of the substrate material. Methods of forming the nano-catalysts are disclosed. The methods typically include functionalizing the surface of the substrate material with a chelating agent, such as a chemical having dissociated carboxyl functional groups (-COO), that provides an enhanced affinity for metal ions. The functionalized substrate surface may then be exposed to a chemical solution that contains metal ions. The metal ions are then bound to the substrate material and may then be reduced, such as by a stream of gas that includes hydrogen, to form metal nanoparticles adjacent the surface of the substrate.
    • 描述了用于形成纳米结构和制造纳米材料的纳米催化剂。 在一些实施方式中,纳米催化剂由粉末基底材料形成,并且在一些实施方式中,纳米催化剂由固体基底材料形成。 在一些实施例中,衬底材料可以包括金属,陶瓷或硅或另一种准金属。 纳米催化剂通常具有邻近基底材料表面设置的金属纳米颗粒。 公开了形成纳米催化剂的方法。 所述方法通常包括用螯合剂(例如具有解离的羧基官能团(-COO)的化学品)对基底材料的表面进行官能化,所述螯合剂对金属离子提供增强的亲和力。 然后可以将官能化的基材表面暴露于含有金属离子的化学溶液。 然后将金属离子结合到基底材料上,然后可以例如通过包含氢气的气流将其还原,以在基底表面附近形成金属纳米颗粒。
