Determination of the surface temperature of magnetically heated nanoparticles using a catalytic approach

“…Although the surface temperatures in those conditions remain unknown, there is experimental evidence of the presence of "hot-spots". Indeed, in previous works, 10,19 we have shown that the hydrodeoxygenation (HDO) of furfural or 2-hydroxymethylfurfural, a reaction typically carried out at high temperature (150-220 °C) and pressure (10-50 bar) in heterogeneous catalysis, 20 can be performed under apparently mild reaction conditions (3 bar of H2) and low catalyst loadings in mesitylene solution when catalyzed by Fe2.2C@Ru or by iron-nickel NPs enriched with Ni (FeNi3@Ni) using magnetic induction. 10,19 The intense local reflux that was observed in the surrounding of the NPs, as well as the catalytic results, suggested that the reaction occurred at a temperature well above the boiling point of the solvent (mesitylene, b.p 165 ºC).…”

Structural Design of Single‐Atom Catalysts for Enhancing Petrochemical Catalytic Reaction Process

“…However, several methods of SACs focus on low loading at present to avoid sintering due to their inherent thermal instability, and when the activation mechanism of reactants/intermediates requires bonding with multiple metal atoms, the ability of SACs to mediate catalytic reactions is limited, and the redispersion of metal NPs to improve the dispersion and atomic efficiency of metals has been studied. [ 123,124 ] Wang et al. [ 125 ] constructed Pt single atom coupled Pt clusters (Pt/TiO 2 ) by redispersing Pt nanoparticles in TiO 2 by CH 3 I/CO treatment, and the redispersed catalyst remained highly stable after Ar heat treatment or 250 °C H 2 /Ar reduction, and showed higher selectivity and activity in hydrodeoxidation reaction by generating surface oxygen, improving C─O cleavage ability without side reaction vacancies (Figure 11e).…”

Chain-length dependent organisation in mixtures of hydrogenous and fluorous ionic liquids

“…[3][4][5][6][7] SILPs are generally prepared by coating the surface of porous, solid supports such as silica with an IL film containing a catalyst, which can be either a homogeneous or nanoparticle system. [8][9][10][11][12][13][14][15][16] In both cases, the solvent environment around the active site(s) of the catalyst and the gas/liquid interface (where gaseous reagents are employed)…”
