CeO2 is a catalytic material of exceptional technological importance, and the precise role oxygen vacancies crucial to greater understanding these oxide materials. In this work, two ceria nanorod samples with different types distributions were synthesized. A direct relationship between concentration larger size vacancy clusters reducibility/reactivity nanosized was revealed. These results may be an important step in designing active sites at surface metal
Using bottom-up chemistry techniques, the composition, size, and shape in particular can now be controlled uniformly for each every nanocrystal (NC). Research into shape-controlled NCs have shown that catalytic properties of a material are sensitive not only to size but also as consequence well-defined facets. These findings great importance modern heterogeneous catalysis research. First, rational synthesis catalysts might achieved, since desired activity selectivity would acquired by simply...
Cerium oxide (CeO2) nanoparticles have been considered as excellent antioxidants and become a focus of numerous studies. However, the mechanism behind antioxidant role in complex biological system has not well-understood. In this work, direct evidence for hydroxyl radical (•OH) scavenging activity CeO2 was established by simple photometric vitro. When methyl violet (MV) reacted with radical, absorbance change indicated level. The presence protected MV competitively reacting •OH, so their...
To eliminate indoor formaldehyde (HCHO) pollution, Pd/CeO2 catalysts with different morphologies of ceria support were employed. The palladium nanoparticles loaded on {100}-faceted CeO2 nanocubes exhibited much higher activity than those {111}-faceted nanooctahedrons and nanorods (enclosed by {100} {111} facets). HCHO could be fully converted into CO2 over the at a GHSV 10 000 h–1 inlet concentration 600 ppm ambient temperature. prepared characterized series techniques. HRTEM, ICP-MS XRD...
CuO nanocrystals with different shapes, i.e. irregular nanoparticles, nanobelts and nanoplatelets, have been synthesized by controlling a few critical synthesis parameters to explore their catalytic properties. It was found that the rate of CO oxidation on nanoplatelets is over six times higher than nanoparticles about three at 110 °C. Based combined characterizations, such as BET, XRD, TEM, HRTEM temperature-programmed reduction, relationship between reactivity shape well predominantly...
Here we report for the first time that H2 bubbles generated by photocatalytic water splitting are effective in layer-by-layer exfoliation of MoS2 nanocrystals (NCs) into few layers. The as-obtained layers can be situ assembled with CdS nanosheets (NSs) van der Waals heterostructures (vdWHs) few-layered MoS2/CdS NSs which, turn, charge separation and transfer, leading to enhanced production activity. vdWHs exhibited a evolution rate 140 mmol g(CdS)−1 h−1 achieved an apparent quantum yield 66%...
Controllable synthesis of ultrasmall atomically ordered intermetallic nanoparticles is a challenging task, owing to the high temperature commonly required for formation phases. Here, metal-organic framework (MOF)-confined co-reduction strategy developed preparation sub-2 nm PdZn nanoparticles, by employing well-defined porous structures calcinated ZIF-8 (ZIF-8C) and an in situ therein. HAADF-STEM, HRTEM, EDS characterizations reveal homogeneous dispersion these within ZIF-8C frameworks. XRD,...
Introducing a second metal species into atomically dispersed metal-nitrogen-carbon (M-N-C) catalysts to construct diatomic sites (DASs) is an effective strategy elevate their activities and stabilities. However, the common pyrolysis-based method usually leads substantial uncertainty for formation of DASs, precise identification resulting DASs also rather difficult. In this regard, we developed two-step specific-adsorption (pyrolysis-free) constructed DAS catalyst featuring FeCo "molecular...
Abstract The state-of-the-art alkaline hydrogen evolution catalyst of united ruthenium single atoms and small nanoparticles has sparked considerable research interest. However, it remains a serious problem that primarily proceeds on the less active instead more efficient in catalyst, hence largely falling short its full activity potential. Here, we report by combining highly oxophilic cerium fully-exposed nanoclusters nitrogen functionalized carbon support, centers are facilely reversed to...
Ceria nanotubes with extended cavities can be obtained by a facile oxidation−coordination-assisted dissolution process of the partially oxidized one-dimensional Ce(OH)3. Moreover, ceria large and thin walls exhibit excellent reducibility high oxygen storage capacity, indicating they are potential novel catalytic materials.
Two types of monolith high-porosity supermacroporous polystyrene materials had been controlled synthesized from water-in-oil Pickering emulsions. The first type, closed-cell (up to 91%) (ca. 500 μm) (CPPs) was prepared by employing amphiphilic carbonaceous microspheres (CMs) as high internal phase emulsion stabilizer without any inorganic salts or further modifying the wettability particles. second hierarchical porous with highly interconnected macropores (IPPs), constructed emulsions...

Abstract Strengthening OH adsorption on electrocatalyst is crucial to promote the rate‐determining water dissociation step of alkaline hydrogen evolution reaction (HER), whereas too‐intensified will poison active sites instead. This dilemma remains one major challenges for improving electrocatalysts’ HER activities. Herein, a surprising finding that strongly adsorbed an ultrafine quinary PtCoCuNiZn nanoalloy can be facilely desorbed via unique gradient desorption pattern reported, which...
