Magnetically Induced Nanocatalysis for Intermittent Energy Storage: Review of the Current Status and Prospects

In Situ EXAFS-Based Nanothermometry of Heterodimer Nanocrystals under Induction Heating

“…However, the accuracy of this approach is limited by the measurement of the temperature of the bulk support environment, without considering the difference in temperature between the NCs and their local support environment. With only ILP values, it is difficult or nearly impossible to use these species in scenarios such as catalysis of thermally sensitive compounds or targeted cell death, where a thermal difference is a key aspect of the work. ,,,,,− Here, we have shown that the correlated Debye model can be used directly to calculate the temperature of the NCs, while the values of ILP can be used to extract the local support environment temperature. ,,, Experimentally, the ILP of the local support environment was directly observed with a thermal imaging camera, and the thermal difference between the local support environment and the NCs was directly compared for complete thermal understanding of the system. Therefore, this study is not only the first to use in situ EXAFS-based nanothermometry to extract thermal measurements in inductively heated systems but also the first to jointly use temperature-dependent EXAFS and the unapproximated correlated Debye model for the determination of temperature.…”

“…The determination of a temperature difference has implications in inductive catalysis, − hyperthermia treatments for the death of cancer cells, − and polymer sciences. , In catalysis, the ability to determine the temperature difference between the NCs and their support material under induction heating is a key step toward performing catalytic reactions on stability-limited reactants. Performing catalysis at room temperature without external heat sources, termed “cold catalysis”, is enabled through the thermal understanding of induction heating. ,,− Using NCs as localized sources of heat through induction paves the way to performing low-temperature reactions without compromising on activity and presents a valuable area of research to explore. The observation of a temperature difference between NCs and the local support environment of up to 73.60 °C significantly improves our thermal understanding of inductive heating in NCs and is a necessary step toward applications in cold catalysis.…”

Fe@SiO2@Ni: An Iron-Based Composite Material for Magnetically Induced Hydrogenation Reactions in Gas and Solution Phases

“…A typical application of this effect is induction cooking, which is present in many households. The increasing popularity of this technology is attributed to the three advantages brought by magnetic heating, namely, (i) contact-less heating, (ii) very high heating ramp, and (iii) energy efficiency of the process (with respect to conventional joule heating). − …”

Induction heating: an efficient methodology for the synthesis of functional core–shell nanoparticles

“…Magnetic nanoparticles (Mag-NPs) can produce high temperatures in short times and in localized spots via hysteresis losses when exposed to an alternating magnetic field (AMF). 1–3 They have found applications in different fields, such as catalysis, 1–3 medicine, 4 and industrial manufacturing, 5 where they offer remarkable advantages such as improved energy efficiency, precise localized heating and swift temperature control. However, synthetic implications of the induction heating phenomena (IH) remain almost unexplored at the nanoscale.…”

[1][2][3] They have found applications in different fields, such as catalysis, [1][2][3] medicine, 4 and industrial manufacturing, 5 where they offer Using magnetic nanoparticles as heating agents under an alternating magnetic field is a hot research topic due to the high efficiency of heat delivery on a localized spot that these materials enable. For applications, magnetic nanoparticles may need additional functionalization; we show here that magnetic induction allows the preparation of nanoparticles displaying a magnetic core and a shell of molybdenum, a metal difficult to obtain at the zerovalent state, FeNi 3 @Mo and Fe 2.2 C@Mo.…”
