Open AccessLow-temperature hydroformylation of ethylene by phosphorous stabilized Rh sites in a one-pot synthesized Rh-(O)-P-MFI zeolite
Zeolites containing Rh single sites stabilized by phosphorous were prepared through a one-pot synthesis method and are shown to have superior activity and selectivity for ethylene hydroformylation at low tempe...

Low-oxidation-state Ru sites stabilized in carbon-doped RuO2 with low-temperature CO2 activation to yield methane
The generation of methane fuel using surplus renewable energy with CO2 as the carbon source enables both the decarbonization and substitution of fossil fuel feedstocks. However, high temperatures are usually requ...

Tutorial: structural characterization of isolated metal atoms and subnanometric metal clusters in zeolites
The encapsulation of subnanometric metal entities (isolated metal atoms and metal clusters with a few atoms) in porous materials such as zeolites can be an effective strategy for the stabilization of those met...

Regioirregular and catalytic Mizoroki–Heck reactions
The palladium-catalysed cross-coupling reaction between alkenes and aryl halides (the Mizoroki–Heck reaction) is a powerful methodology to construct new carbon–carbon bonds. However, the success of this reacti...

Structural modulation and direct measurement of subnanometric bimetallic PtSn clusters confined in zeolites
Modulating the structures of subnanometric metal clusters at the atomic level is a great synthetic and characterization challenge in catalysis. Here, we show how the catalytic properties of subnanometric plati...

Regioselective generation and reactivity control of subnanometric platinum clusters in zeolites for high-temperature catalysis
Subnanometric metal species (single atoms and clusters) have been demonstrated to be unique compared with their nanoparticulate counterparts. However, the poor stabilization of subnanometric metal species towa...

CO Oxidation Activity of a Au/Ceria-Zirconia Catalyst Prepared by Deposition–Precipitation with Urea
The activation of a 2.6 wt% Au/Ce0.62Zr0.38O2 catalyst prepared by deposition–precipitation with urea is investigated. At 298 K, the activity for CO oxidation of the as-prepared sample is very low; it is signific...
