一般来说，大多数具有多孔结构的碳基空心球的制备方法是所谓的硬模板法。在本文中，我们提出了一种无模板的方法来制备多壳结构的氧化镁/铂中空球。所制备的镁铂空心球具有高度的孔道和自支撑结构，其比表面积高达16.7m2g−1。此外，我们的研究表明，所制备的多壳层镁铂中空球对甲醇的氧化反应具有较高的电催化活性和长期稳定性。
In general, most carbon-based hollow spheres with porous structures are prepared using the so-called hard-template method. In this paper, we present a template-free strategy for the fabrication of multiple-shell MgO/Pt hollow spheres. The as-prepared MgO/Pt spheres have a highly porous and self-supporting structure with a high surface area of 16.7 m2 g−1. Moreover, our research indicates that the as-prepared multiple-shell MgO/Pt hollow spheres exhibit enhanced electrocatalytic activity and long-term stability towards the oxidation reaction of methanol.
