  Weakly bound capping agents on gold nanoparticles in catalysis: Surface poison?

  摘要：

  The influence of the concentration and nature of weakly bound capping agents on the catalytic activity and selectivity of gold nanoparticles is explored in the selective liquid phase oxidation of benzyl alcohol with oxygen and complemented with a detailed XPS analysis. Two nitrogen-based capping agents, dode-cylamine (DDA) and poly(vinyl-pyrrolidone) (PVP) and different gold catalysts (supported and unsupported gold nanoparticles, a reference gold catalyst with and without exposure to capping agents) have been used. The colloid nanoparticle-based catalyst exhibits a high activity at mild conditions (TOF = similar to 10(4) h(-1) at 353 K in air). The interaction of alumina support-nanoparticle induces the presence of cationic gold and more surface gold atoms and, hence, catalytic activity although capping agent is still present. The activity is the highest for the largest gold particles (similar to 6.4 nm), correlating with sites in larger surface planes.Weakly bound capping agents lower the accessibility to the active sites and may act as catalyst surface poison. Selecting the appropriate capping agent for the nanoparticles synthesis (weakly adsorbing on the particle and promoting polycrystallinity), nanoparticles with twinning defects and enhanced catalyst activity are produced, compensating the negative effect of diffusional hindrance. On the other hand, the selectivity to benzaldehyde at higher conversions is dominated by gold particle size, increasing with decreasing size, and independent of the presence of capping agents and twinning defects.

  The present invention provides a colorless, transparent polyimide composite film containing a polyimide (A) having a specific repeating unit, and an organic-treated layered silicate (B) obtained through treatment with an organic onium ion having a specific structure such that the organic-treated layered silicate (B) is dispersed in the polyimide (A); and as well a method for producing a colorless, transparent polyimide composite film, the method including forming a film-form mixture through extrusion or application, onto a support, of a three-component liquid mixture containing the polyimide (A), the organic-treated layered silicate (B), and an organic solvent (C) having a specific SP value; and subsequently removing the organic solvent (C) from the film-form mixture. The polyimide composite film of the present invention is a colorless, transparent film containing the polyimide (A) and the organic-treated layered silicate (B) which is very uniformly dispersed in the polyimide, exhibiting excellent heat resistance and mechanical properties, and exhibiting flexibility.
