“…Indeed, using the knowledge of complex nanomaterials synthesis, we have been able to design magnetic nanoparticles (Mag-NPs) with exceptional heating power able to trigger different catalytic reactions, over a broad range of temperatures (200 to 700 °C), either in solid–gas catalysis or in solution. Ferromagnetic particles of iron carbide, ,− iron cobalt, , iron-nickel, , or nickel-cobalt ,,, display different magnetic properties and Curie temperatures and hence can address different reactions. In some cases, a shell composed of Cu, Ni, , Ru, or Pt has been added to obtain better catalytic performances.…”

Recently, magnetically induced catalytic CO2 hydrogenation has gained attention due to its high energy efficiency and better heat management of exothermic processes compared to thermal heating. Ferromagnetic nanoparticles combining heating and catalytic properties are shown to be efficient, but the complex synthesis procedure limits their potential as industrial products. In this work, commercially available iron (Fe) wool was chemically modified by a sol–gel coating of a silica (SiO2) layer followed by nickel (Ni) particle deposition and employed as a catalyst for magnetically induced gas-phase CO2 hydrogenation reaction. The composite material was thoroughly characterized by combined X-ray photoelectron spectroscopy (XPS), focused ion beam scanning electron microscopy (FIB-SEM), and magnetic and specific absorption rate (SAR) measurements as well as its catalytic activity. This material shows an enhanced catalytic activity (higher CO2 conversion and CH4 selectivity) compared to Ni-only-coated iron wool, which could be attributed to the stabilization of the composite catalyst. Adding a Siralox filler in the catalytic bed further improves CO2 conversion, CH4 selectivity, and catalyst stability. Furthermore, this composite catalyst is demonstrated to be active for solution-phase model hydrogenation and hydrodeoxygenation reactions, thus anticipating its potential for a broader range of catalytic applications in organic chemistry.

This comprehensive review explores the potential of radio‐frequency (RF) induction heating in chemical reactions, explicitly focusing on magnetically induced catalysis using magnetic nanoparticles (NPs). We trace the recent historical progress of induction heating and highlight the advancements in liquid and gas‐phase reactions, particularly in its integration with heterogeneous catalysis. The review finds that induction heating profoundly impacts reaction kinetics, and selectivity, and can even reduce overpotentials in electrocatalytic processes. A final outlook unveils the challenges and opportunities associated with aspects such as fundamental research and reactor design, with a particular focus on expanding its use to higher pressures and necessary optimizations to improve energy efficiency. Moreover, it highlights the pressing need for standardized reporting in induction‐heated catalysis. The study underscores the significance of this brand‐new field in developing efficient and sustainable catalytic processes, which are essential for meeting the growing demand for clean energy and sustainable chemical production.

The advantages of ammonia as a hydrogen carrier have led to proposals for on-site hydrogen production through its decomposition. Rapid cold start of ammonia decomposition is crucial for applications such as ammonia-powered vehicles, but conventional heating methods are challenged by the high decomposition temperature of ammonia. In this study, we successfully achieved the rapid cold start of ammonia decomposition using Co nanoparticle catalysts driven by magnetic induction heating, demonstrating excellent catalytic performance and stability. The magnetic induction heating-driven ammonia decomposition system was integrated with a hydrogen fuel cell, proving its ability to achieve the cold start of ammonia decomposition within 10 s, as demonstrated by comparative experiments using 75% H 2 -25% N 2 from a gas cylinder as the control. This study provides a deeper understanding of hysteresis heating catalysis, promoting the practical use of ammonia as a hydrogen carrier for rapid hydrogen production in the energy industry.
