Abstract null null We designed a Ni-exsolved perovskite catalyst for the high-temperature water-gas shift reaction. The perovskite particle has the formula of La0.9Fe0.95Ni0.05O3 and has metal nanoparticles (NPs) exsolved on its surface after reduction treatment. XRD, SEM, HR-TEM and XPS analyses were used to confirm the existence of the exsolved Ni metal NPs. This catalyst provided higher CO conversion and H2 yield, and exceptionally better catalytic stability than the commercial catalyst. Temp...

Abstract null null The synthesis of aromatic ketimines via hydroamination of phenylacetylenes (PAs) with anilines (ANs) has been accomplished in high yields and with excellent regio- and stereo-selectivity using gold nanoparticles (AuNPs) embedded in crystalline syndiotactic polystyrene-cis-1,4-polybutadiene (sPSB) multiblock copolymer matrix. The performances of the AuNPs-sPSB catalyst exceed those of the other commercial gold catalysts as a result of the physical chemical properties of the nan...

Abstract Photocarriers and reactants are two crucial factors in photocatalytic reactions, the divergence between them severely limits the photocatalytic performance. Herein, we proposed a light-controlled method to converge photocarriers and reactants to the same location. Based on energy band engineering, we adjust the wavelength of the irradiated light to selectively grow cocatalyst in the desired position in a semiconductor. The pinpointed growth of the cocatalyst serves as a bridge between t...

Abstract null null For supported metal catalysts, the underlying support not only disperses and stabilizes metal particles, but also modulates their electronic structures remarkably, and even directly participates in catalytic reactions. Here we report that Pd nanoparticles (NPs) supported on oxygen-functionalized carbon black (Pd/O-C) show an unexpected inverse trend of selectivity on Pd particle size in chemoselective hydrogenation of para-chloronitrobenzene (p-CNB), compared to those on carbo...

Abstract null null This study shows remarkably different features between the oxidation of secondary and primary C3-C5 alcohols. The oxidation of primary alcohols is controlled by the oxidative removal of blocking adsorbates, such as CO, formed after the dissociative adsorption of alcohol molecules. Conversely, secondary alcohols do not undergo dissociative adsorption and therefore their oxidation is purely controlled by the energetics of the elementary reaction steps. In this respect, a differe...

Abstract null null The use of shape-controlled nanomaterials represents an elegant way to improve the performance of many electrochemical reactions. However, two main aspects must be still optimised: decreasing particle size and increasing their activity. This study shows that the deposition of Pd on different small (3–5 nm) supported Pt materials (displaying a preferential structure containing ~40% of Pt{1 0 0} terraces) leads to a great enhancement in the electrocatalytic activity towards the ...

Abstract null null Transition metal carbides and nitrides (TMCs and TMNs) have attracted much attention due to their unique physical and chemical properties brought by the incorporation of interstitial carbon and nitrogen into the crystal lattice of the parent metals. Recent advances in utilizing TMCs and TMNs have revealed their intriguing catalytic properties in many industrially important reactions, including heteroatom removal, CO2 activation, alcohol reforming, and water-gas shift reactions...

Abstract null null A new bismuth molybdate, obtained by means of microwave-assisted hydrothermal synthesis, is described by the chemical formula: β(L)-Bi2Mo2O9, in accordance with its low crystallization temperature and transition to β-Bi2Mo2O9 at 532°C. Its structure, solved ab initio using powder diffraction data, crystallizes in the monoclinic system (space group P21/c), with a = 8.11413(5), b = 8.54445(5), c = 13.43623(6) A, and β = 123.5085(2)°. This phase has been tested as a catalyst for ...

Abstract In this manuscript, we investigated in detail one of the critical parameters that governs the reactivity of the carbonylic group towards hydrogenation and hydrodeoxygenation: the effect of the side chain of aldehydes. We observed that the presence of a π-electron conjugation on the side chain strongly affects the conversion of aldehydes to alcohols and hydrocarbons under the reaction conditions studied. In particular, the presence of a strong π-electron conjugation, such as the aromatic...

Abstract Selective and stable production of C2 oxygenates from syngas is enabled by a phosphate-passivated mordenite catalyst used in tandem with a commercial Cu/ZnO/AlMgOx catalyst. Unmodified mordenite used in this arrangement is accompanied by substantial hydrocarbon formation and carbon deposition. Therefore, phosphate groups are used to remove or significantly reduce Bronsted acidity in mordenite by capping aluminum sites. Such groups are stable to calcination and catalyst regeneration. Tri...
