One-Pot Protocol for Au-Based Hybrid Magnetic Nanostructures via a Noble-Metal-lnduced Reduction Process

摘要

In the past decades, catalysts based on Au nanoparticles have attracted considerable attention. However, because of the limited reserves of Au materials, it is urgent to reduce their usage. As we know, complex nanoobjects containing two or more different materials in the same nanoparticle can not only combine properties of the individual constituents but also show unique and superior properties different from ordinary materials. Therefore, hybrid nanocrystals consisting of Au and non-noble metals (particularly inexpensive first-row transition metals) may offer opportunities for reducing Au usage and the overall cost of catalysts.
