Magnetically induced catalysis using magnetic nanoparticles (MagNPs) as heating agents is a new efficient method to perform reactions at high temperatures. However, the main limitation is the lack of stability of the catalysts operating in such harsh conditions. Normally, above 500 °C, significant sintering of MagNPs takes place. Here we present encapsulated magnetic FeCo and Co NPs in carbon ( and ) as an ultrastable heating material suitable for high-temperature magnetic catalysis. Indeed, or a mixture of decorated with Ni or Pt-Sn showed good stability in terms of temperature and catalytic performances. In addition, consistent conversions and selectivities regarding conventional heating were observed for CO methanation (Sabatier reaction), propane dehydrogenation (PDH), and propane dry reforming (PDR). Thus, the encapsulation of MagNPs in carbon constitutes a major advance in the development of stable catalysts for high-temperature magnetically induced catalysis.
使用磁性纳米颗粒（MagNPs）作为加热剂的磁诱导催化是一种在高温下进行反应的新型高效方法。然而，主要限制是在如此苛刻条件下运行的催化剂缺乏稳定性。通常，在500℃以上，MagNPs会发生显著烧结。在此，我们展示了碳包覆的磁性FeCo和Co纳米颗粒作为适用于高温磁催化的超稳定加热材料。实际上，用Ni或Pt-Sn修饰的 或其混合物在温度和催化性能方面表现出良好的稳定性。此外，对于CO甲烷化（萨巴蒂尔反应）、丙烷脱氢（PDH）和丙烷干重整（PDR），观察到与传统加热一致的转化率和选择性。因此，将MagNPs包覆在碳中是开发用于高温磁诱导催化的稳定催化剂的一项重大进展。
