Abstract Pd‐based nanosheet materials have emerged as efficient catalysts for monobasic and polyhydric alcohol oxidation reactions. However, most reported synthetic methods of nanosheets (NSs) are nonuniversal surfactant‐involved, leading to residue‐covered surfaces with drastically damaged electrocatalytic properties. Herein, a universal, surfactant‐free, simple one‐pot route is developed the precise synthesis kind novel self‐standing Pd–M (M = Ag, Pb, Au, Ga, Cu, Pt, etc.) NSs...
Palladium nanoparticles covered with liquid-crystal molecules were prepared by UV irradiation of an alcohol solution palladium(II) acetate in the presence molecules. The Pd have average diameter 2.5 nm. A twisted nematic (TN) device (LCD) was fabricated doping another kind In this sign dielectric anisotropy (Δε) molecules, which cover nanoparticles, is opposite to that work as host (Δε>0). TN-LCD cell research exhibits a frequency modulation response applied alternative voltage wave form.
Ag-Pd bimetallic nanoparticles were prepared directly in ultrathin TiO(2)-gel films by a stepwise ion-exchange/reduction approach. Ion-exchange sites created using Mg(2+) ions as template. Ag(+) ion was then incorporated exchange, and converted into metallic low-temperature H(2) plasma, regenerating ion-exchange sites. The same procedure carried out for Pd(2+) ion, producing Pd-on-Ag nanoparticles, TEM observation plasmon resonance absorption indicate. By contrast, reversed metal...
