Abstract

The classical strong metal–support interaction between TiO2 and IB metals was demonstrated.

Pd Nanoparticles Supported on Triangle‐Shaped La2O2CO3 Nanosheets: A New Highly Efficient and Durable Catalyst for Selective Hydrogenation of Cinnamaldehyde to Hydrocinnamaldehyde

“…Previous reports found that physicochemical interactions generated by these associationsb etween the metal and the support can also influence catalyticp roperties, which have been linked to the strong metal-support interaction (SMSI). [20][21][22][23] Guo et al [24] altered the size regimes of the Ru depositsi nR u/CeO 2 assemblies and uncoveredt he relationship with the SMSI. Shen et al [25] reported that Cu/CeO 2 catalysts are highly active for the low-temperature water-gas shift reaction and revealed that the reaction occurs at the copper/ceria interfacial perimeter due to the SMSI.…”

Control of Catalytic Activity of Nano‐Au through Tailoring the Fermi Level of Support

“…High‐resolution transmission electron microscopy (HRTEM) of the nanoparticles suggest that the lattice spacing is about 0.230 nm, which can be attributed to the (111) plane of Au. Importantly, the Au nanoparticles over all the spinel supports are naked with no encapsulation caused by the classical SMSI . Statistics shows that the average sizes of Au nanocrystals supported on ZnCo 2 O 4 , ZnFe 0.5 Co 1.5 O 4 , ZnFeCoO 4 , ZnFe 1.5 Co 0.5 O 4 , and ZnFe 2 O 4 are 3.0 ± 0.7, 3.0 ± 0.8, 3.1 ± 0.7, 3.2 ± 0.7, and 3.4 ± 0.7 nm, respectively, indicating the negligible influence of the ZnFe x Co 2− x O 4 composition on the size distribution of nano Au.…”

Boosting Alkaline Hydrogen Evolution Electrocatalysis over Metallic Nickel Sites through Synergistic Coupling with Vanadium Sesquioxide

“…Metal–metal oxide catalysts have been widely recognized as an asset for reinforcing catalytic performances in chemical catalysis reactions . Following the strategy of synergistic interfaces in HER, many nanostructured interfaces have been developed, usually with one component based on an oxidized 3d transition metal as a water dissociation site to adsorb hydroxy groups and another component to adsorb hydrogen atoms and desorb hydrogen molecules .…”

“…[2] Metal-metalo xide catalysts have been widely recognized as an asset for reinforcing catalytic performances in chemical catalysis reactions. [8][9][10][11] Following the strategy of synergistic interfaces in HER, [12] many nanostructured interfacesh ave been developed,u sually with one component based on an oxidized 3d transition metal as aw ater dissociation site to adsorb hydroxy groups and another component to adsorb hydrogen atoms and desorbh ydrogen molecules. [13][14][15] With this in mind, we considered ways to design and synthesize various high-efficiency metal-metal oxide HER catalysts rationally and controllably.V anadium-based oxides are earth-abundant, inexpensive, and versatile in their electronic structures, and may be regarded as apromising candidatefor electrocatalysis promoters.…”
