“…Besides α‐TiO 2 , SnO 2 is another typical oxide with rutile structure. It is also a n ‐type semiconductor with big band gap, extensively applied in gas semiconductor sensors, batteries, and catalysts . With increasing interest in morphology dependent performance of various inorganic materials, studies on morphologically optimized SnO 2 synthesis and correlation between structure and performance have been extensively reported.…”

Surface/interfacial catalysis on a series of oxide substrates and metal/oxide interfaces has been reviewed. Special attention has been paid to those systems in which the oxide substrates are structurally defined with certain exposed facets, and the metal assembling is well controlled with desired particle size and narrow particle size distribution. The distinct catalytic behaviors over the selected systems have been discussed in line with their specific surface/interfacial structure features as well as other surface properties. The tactics and cations how to build up the novel metal/oxide interfacial structures are provided, and the guideline for extended reaction exploration is also suggested. Success in structure and performance control on these important systems is highly valuable for designing more selective and efficient catalyst in practical applications.

“…The target temperature is reached within few seconds and the energy is directly transferred inside the material without the need for heating the whole reactor system. This technology appeared first as an engineer solution for fast heating catalytic reactors, making use either of the walls of the reactor [10][11][12] or from heating elements embedded inside, such as iron balls or ferrite microparticles. [1,13,14] We have demonstrated the possibility to magnetically induce CO 2 methanation in a continuous-flow reactor using core-shell NPs consisting of Ni or Ru coated iron carbide cores displaying high heating properties.…”

“…[22] The quasi instantaneous nature of magnetic heating seems well-adapted to the storage of intermittent energy, a promising solution being CO 2 methanation. [23][24][25] A large variety of catalysts has been investigated (Ni, Ru, Fe, Rh), [12,13] but Ni based catalysts are the most largely employed because of their high performance and low cost. [23] It has however previously been proposed through DFT calculations that Fe-Ni catalysts are more active than monometallic catalysts for CO 2 methanation since they combine good CO adsorption and CO dissociation.…”

Induction heating of magnetic nanoparticles (NPs) is a method to activate heterogeneous catalytic reactions. It requires nano‐objects displaying high heating power and excellent catalytic activity. Here, using a surface engineering approach, bimetallic NPs are used for magnetically induced CO2 methanation, acting both as heating agent and catalyst. The organometallic synthesis of Fe30Ni70 NPs displaying high heating powers at low magnetic field amplitudes is described. The NPs are active but only slightly selective for CH4 after deposition on SiRAlOx owing to an iron‐rich shell (25 mL min−1, 25 mT, 300 kHz, conversion 71 %, methane selectivity 65 %). Proper surface engineering consisting of depositing a thin Ni layer leads to Fe30Ni70@Ni NPs displaying a very high activity for CO2 hydrogenation and a full selectivity. A quantitative yield in methane is obtained at low magnetic field and mild conditions (25 mL min−1, 19 mT, 300 kHz, conversion 100 %, methane selectivity 100 %).

Iron oxide (Fe2O3) or copper oxide (CuO) was loaded on a monolithic porous α-Al2O3 support, which was placed inside the coaxial electrodes of plasma reactor. The IPA decomposition efficiency itself hardly depended on the presence and type of metal oxides because the rate of plasma-induced decomposition was so fast, but the behavior of byproduct formation was largely affected by them. The concentrations of the unwanted byproducts, including acetone, formaldehyde, acetaldehyde, methane, carbon monoxide, etc., were in order of Fe2O3/α-Al2O3 < CuO/α-Al2O3 < α-Al2O3 from low to high. Under the condition (flow rate: 1 L min -1 ; IPA concentration: 5,000 ppm; O2 content: 10%; discharge power: 47 W), the selectivity towards CO2 was about 40, 80 and 95% for α-Al2O3, CuO/α-Al2O3 and Fe2O3/α-Al2O3, respectively, indicating that Fe2O3/α-Al2O3 is the most effective for plasma-catalytic oxidation of IPA. Unlike plasma-alone processes in which tar-like products formed from volatile organic compounds are deposited, the present plasma-catalyst hybrid system did not exhibit such a phenomenon, thus retaining the original catalytic activity.
