Confining peroxide to make methanol In principle, hydrogen would be an efficient oxidant for the conversion of methane under mild conditions. practice, however, it is currently too expensive produce ahead time this purpose. Jin et al. report a catalyst system that generates and concentrates immediate reaction with methane. A hydrophobically coated zeolite keeps close gold palladium active site, where incoming then selectively oxidized methanol. Science , issue p. 193
To address the limitations of batch organic-aqueous biphasic catalysis, we develop a conceptually novel method termed Flow Pickering Emulsion, or FPE, to process reactions in continuous flow fashion. This involves compartmentalization bulk water into micron-sized droplets based on water-in-oil emulsion, which are packed column reactor. The compartmentalized can confine water-soluble catalysts, thus "immobilizing" catalyst reactor, while interstices between allow organic (oil) phase flow. Key...
The possible synergistic mechanisms of BPA degradation on YSCCSs.
Abstract A continuous flow cascade of multi-step catalytic reactions is a cutting-edge concept to revolutionize stepwise synthesis yet still challenging in practical applications. Herein, method for one-pot catalysis developed by combining Pickering emulsions with flow. Our involves co-localization different catalytically active sub-compartments within droplets emulsion yielding cell-like microreactors, which can be packed column reactor catalysis. As exemplified two chemo-enzymatic the...
We describe a novel method to prepare liquid–solid hybrid catalyst via interfacial growth of porous silica crust around Pickering emulsion droplets, which allowed us overcome the current limitations both homogeneous and heterogeneous catalysts. The inner micron-scaled liquid (for example, ionic liquids) pool resultant can host free molecular catalysts or enzymes create true catalysis environment. has excellent stability, makes it amenable packing directly in fixed-bed reactors for continuous...
Abstract CeO 2 doped with various rare earth (RE) ions (Sm, Y, La and Nd) having a broom‐like hierarchical structure was successfully prepared by template‐free hydrothermal method. The photooxidation performance of RE‐doped products significantly better than that pure , comparative experiments showed Sm‐doped (SC) has superior activity, resulting about 3.0‐times 8.5‐times higher activities bisphenol A (BPA) degradation acetaldehyde (CH 3 CHO) decomposition, respectively, those . Due to the...
The nucleation and growth of palladium clusters supported on anatase TiO2(101) surface has been studied using periodic supercell models density functional theory. most active site for single Pd adatom the perfect is bridge formed by two two-coordinated oxygen (2cO) atoms at step edge with highest adsorption energy 2.18 eV. On defective surface, effect vacancy not as strong that in Pt or Au deposition case. shift sites dimer growing to trimer observed. both surfaces, adsorbed Pd3 prefer form...
The bottom-up assembly of biomimetic multicompartmentalized microreactors for use in continuous flow catalysis remains a grand challenge because the structural instability or absence liquid microenvironments to host biocatalysts existing systems. Here, we address this using strategy that combines stepwise Pickering emulsification with interface-confined cross-linking. Our allows fabrication robust liquid-containing (MLMs), whose interior architectures can be exquisitely tuned fashion. With...
Based on the confinement of Pickering emulsion droplets, a novel method to “immobilize” IL catalysts has been developed successfully for continuous-flow cyanosilylation reaction.
Abstract Robust millimeter-sized spherical particles with controlled compositions and microstructures hold promises of important practical applications especially in relation to continuous flow cascade catalysis. However, the efficient fabrication methods for producing such remain scare. Here, we demonstrate a liquid marble approach fabricate robust mm-sized porous supraparticles (SPs) through bottom-up assembly silica nanoparticles presence strength additive or surface interactions, without...
Nitrogen and sulfur-co-doped ceria with a regular nanorod morphology was prepared by one-step calcination treatment. N S dopants can generate new impurity level states promote the photocatalytic performance of CeO 2 for VOCs degradation.
Abstract Although organic/aqueous biphasic catalysis reactions are widely used, it is difficult to effectively control their reaction process. Here we develop a solid particles‐stabilized emulsion (Pickering emulsion) strategy address this limitation. A challenging reaction, selective hydrogenation of benzene cyclohexene, was investigated as case. The developed Pickering system exhibited higher efficiency and selectivity than the conventional even under mild stirring. cyclohexene yield in...
First-principles density functional theory studies have been carried out to investigate the effects of perfect and defective anatase TiO2 supports on structural stabilities electronic properties PdmAgn(m + n = 2–5) bimetallic clusters. Our results showed that structures supported Pd–Ag clusters are distorted compared their in gas phase, which is caused by balance cluster inner-interaction metal-support interfacial interaction. In particular, Pd1Ag3 Pd1Ag4 prefer form three-dimensional both...
Usually, the one-step benzene hydroalkylation to produce cyclohexylbenzene (CHB) can proceed on metal-acid bifunctional catalysts. In this work, we developed a highly active mixed catalyst composed of Ru-based hydrogenation (Ru–Zn) and metal-free HBeta alkylation zeolite for efficient CHB under batch-operation or continuous-flow conditions. It was shown that partial generated cyclohexene (CHE) intermediate Ru–Zn subsequently with CHE produced zeolite. The as-combined Ru–Zn|HBeta showed an...
Abstract The hydrothermal method is widely applied in nanomaterials synthesis, and most of the influencing factors have already been taken into account. However, effect atmosphere solution on performance has underestimated for a long time. In this article, reaction solvents were saturated with three classical gases (argon, oxygen, carbon dioxide), then heated at 180 °C 24 h to obtain cerium dioxide (CeO 2 ) nanoparticles. properties types CeO are significantly different from that normal...
Enhancing or restoring enzyme functions under cell-free conditions with good stability is typically difficult to achieve in traditional systems since the inherent conformation structure of enzymes highly dependent on their surroundings. Here, we describe construction silica microreactors a biological-friendly aqueous environment for long-term continuous-flow enzymatic reactions. Based simple sol–gel growth process precursor around within enzyme-containing Pickering droplets, biomimetic...
