Facet-dependent activity of shape-controlled TiO2 supported Au nanoparticles for water-gas shift reaction†

The bifunctional role of noble metal/oxide interface in the activation of reactants is of vital importance in heterogeneous catalysis of water-gas shift (WGS) reaction. Herein, three types of shape-controlled TiO2...

Nonoxidative Coupling of Ethane with Gold loaded Photocatalysts

Direct and continuous conversion of ethane to yield n-butane and hydrogen at near room temperature (ca. 320 K) was examined with gold loaded gallium oxide and titanium dioxide photocatalysts without...

In-situ FTIR to unravel the bifunctional nature of aromatics hydrogenation synergy on zeolite / metal catalysts

Acid sites, in particular Brønsted sites, are often reported to enhance the catalytic performance of metal catalysts, like platinum, in hydrogenation. The significant boost in catalytic performance suggests a bifunctional...

Role of Quantum-size Effects on the Dehydrogenation of CH4 on 3d TMn Clusters: DFT Calculations Combined with Data Mining

In this work, we report a theoretical investigation of the role of quantum-size effects (QSE) on the dehydrogenation of methane (CH4) on 3d transition-metal clusters, TMn , where TM =...

Time-resolved in situ DRIFTS study on NH3–SCR of NO on CeO2/TiO2 catalyst

Ce–Ti catalysts were considered as promising replacement for V–Ti based catalysts for selective catalytic reduction (SCR) of nitrogen oxides (NO and NO2) with NH3. In this work, CeO2/TiO2 catalyst was...

Lanthanum-based double perovskite nanoscale motifs as support media for the methanol oxidation reaction

We have correlated the performance of double perovskite metal oxides as support media for the methanol oxidation reaction (MOR) with their intrinsic size, shape, and composition.

Phase Segregation via Etching-Induced Cation Migration in CoSx-ZnS Nanoarchitectures for Solar Hydrogen Evolution

Low charge carrier mobility limits the development of highly efficient semiconductor-based photocatalysis. Heterointerface engineering is a promising approach to spatially separate the photoexcited charge carriers and thus enhance photocatalytic activity....

Effect of CeO2 morphology on the catalytic properties of Au/CeO2 for base-free glucose oxidation

Catalytic selective oxidation of glucose into value-added gluconic acid is one of the sustainable routes for biomass utilization, for which the supported Au catalysts have been widely explored. Au/CeO2 was...

A S-scheme heterojunction constructed by α-Fe2O3 and In-doped carbon nitride for high-efficiency CO2 photoreduction

The conversion of CO2 to chemicals and fuels by photocatalysis provides a promising strategy to solve both energy crisis and environmental impacts, for which the development of high-activity photocatalysts is...
