As an efficient non-precious metal catalyst, FeCo alloy was widely used in various catalytic reactions. Owing to the organic pollution in ecosystem, it has attracted much attention in heterogeneous Fenton reaction. Unfortunately, their application was restricted by slow process and high leaching. To overcome these shortcomings simultaneously, herein, [email protected] graphitized carbon (NGC) core/shell composite was synthesized via one-step annealing Prussian blue analogue. In microwave assisted Fenton reaction (MAFR), malachite green (MG) degradation time was only 2.5 min, and the rate constant was 2.0 min⁻¹, about 20 times higher than heterogeneous Fenton reaction. Synergistic index was 3.88, meaning extra 288% of removal efficiency was yield in peroxymonosulfate (PMS)[email protected] system. The effect of microwave-activation was divided into thermal effect and non-thermal effect. SO₄^·− produced through thermal effect occupied 73% ± 8% of total number. The contribution of thermal effect was estimated to be 65% ± 7% for MG removal. Non-thermal effect was clarified by hotspots effect theory. Due to protection of NGC shell, Co^3+/2+ leaching in composite was only one-tenth of pure FeCo. [email protected] composite could be rapidly recycled due to ferromagnetic behavior with saturation magnetization of 98.7 emu/g. 89.3% of degradation efficiency was maintained after the 5^th cycle.

作为一种有效的非贵金属催化剂，FeCo合金广泛用于各种催化反应中。由于生态系统中的有机污染，它在非均相芬顿反应中引起了广泛的关注。不幸的是，它们的应用受到缓慢的过程和高浸出的限制。为了同时克服这些缺点，本文中，通过一步退火普鲁士蓝类似物合成了[电子邮件保护的]石墨化碳（NGC）核/壳复合材料。在微波辅助的Fenton反应（MAFR）中，孔雀石绿（MG）的降解时间仅为2.5分钟，速率常数为2.0分钟^-1比异质Fenton反应高约20倍 协同指数为3.88，这意味着过氧化一硫酸盐（PMS）[电子邮件保护]系统的去除效率可提高288％。微波活化的作用分为热作用和非热作用。通过热效应产生的SO ₄ ^·−占总数的73％±8％。MG去除的热效应贡献估计为65％±7％。热点效应理论阐明了非热效应。由于NGC壳的保护，复合物中Co ^{3 + / 2 +的}浸出仅为纯FeCo的十分之一。[受电子邮件保护的]复合材料由于铁磁性能而可以快速回收利用，其饱和磁化强度为98.7 emu / g。5次后保持89.3％的降解效率^第一个周期。
