The tailored chemical synthesis of binary and ternary alloy nanoparticles with a uniform elemental composition is presented. Their dual use as magnetic susceptors for induction heating and catalytic agent for steam reforming of methane to produce hydrogen at temperatures near and above 800 °C is demonstrated. The heating and catalytic performance of two chemically synthesized samples of CoNi and CuCoNi are compared and held against a traditional Ni‐based reforming catalyst. The structural, magnetic, and catalytic properties of the samples were characterized by X‐ray diffraction, elemental analysis, magnetometry, and reactivity measurements. For induction‐heated catalysts, the conversion rate of methane is limited by chemical reactivity, as opposed to the case of traditional externally heated reformers where heat transport limitations are the limiting factor. Catalyst production by the synthetic route allows controlled doping with miniscule concentrations of auxiliary metals.

专为高温感应加热蒸汽甲烷重整而设计的双功能钴镍纳米颗粒

提出了具有均匀元素组成的二元和三元合金纳米粒子的定制化学合成方法。证明了它们在感应加热和感应剂中的双重用途,它们在接近和高于800°C的温度下用作甲烷蒸汽重整以生产氢气的催化剂。的两个化学合成的样品的加热和催化性能的CoNi的CoNi将其与传统的镍基重整催化剂进行比较并进行比较。通过X射线衍射,元素分析,磁力测定和反应性测量来表征样品的结构,磁性和催化特性。对于感应加热的催化剂,甲烷的转化率受化学反应性的限制,这与传热限制是限制因素的传统外部加热重整器的情况相反。通过合成路线生产催化剂,可实现微量掺杂的辅助金属的受控掺杂。
