Tailoring nano-catalysts: turning gold nanoparticles on bulk metal oxides to inverse nano-metal oxides on large gold particles.
Highly active/stable inverse catalysts of nano-oxides on large gold particles are designed and tailored. For the gas-phase oxidation of alcohols as a model reaction, the experimental and theoretical results verify that the catalyst activity depends on the gold-oxide interface, and the anti-sintering feature of such an inverse structure endows the catalyst with high stability.
متن کاملSolid acid catalysts based on supported tungsten oxides
Supported WOx clusters are active and stable catalysts for isomerization, dehydration, and cracking reactions. Brønsted acid sites form on WOx clusters when a lower valent element replaces W6+ or when W6+ centers reduce slightly during catalytic reactions. WOx clusters of intermediate size provide the balance between reducibility and accessibility required to maximize the number of surface H+ s...
متن کاملPolylactic acid (PLA)
This website provides an excellent overview of PLA as a polymer, its properties, and manufacture. This web article describes the production of lactic acid from biomass by microbial fermentation coupled to a poly-merization process to make PLA. The article is a bit dated and its industrial projections are now seen to be a bit over-optimistic. NatureWorks is the company that started large-scale p...
متن کاملMetal Fluorides, Metal Chlorides and Halogenated Metal Oxides as Lewis Acidic Heterogeneous Catalysts. Providing Some Context for Nanostructured Metal Fluorides.
Aspects of the chemistry of selected metal fluorides, which are pertinent to their real or potential use as Lewis acidic, heterogeneous catalysts, are reviewed. Particular attention is paid to β-aluminum trifluoride, aluminum chlorofluoride and aluminas γ and η, whose surfaces become partially fluorinated or chlorinated, through pre-treatment with halogenating reagents or during a catalytic rea...
متن کاملEffect of Clay Network Formation on Flame Retardancy of Polyethylene terephthalate/montmorillonite Nanocomposites
Considering the importance of determining potential hazards and factors that can cause anunexpected fire and due to the important role of nanotechnology to achieve more effectiveproperties, this paper presents our experiments on preparing nanocomposites based onPoly(ethylene terephthalate)(PET) and montmorillonite (MMT) as organoclay via meltblending with different clay loadings to investigate ...
