In this paper, we investigate the plasmonic coupling effects on the localized surface plasmon resonances (LSPRs) of palladium nanoparticle chains. We show the transmission electron microscopy (TEM) images and the extinction cross-section spectra of near-contact palladium nanoparticle chains from monomer to pentamer. The extinction spectra of chains nanoparticles were measured by far-field polarization spectroscopy over a large spectral range (ultraviolet, visible and near-infrared) and compared with numerical calculations based on finite element method (FEM). For single palladium nanoparticle, the LSPR phenomenon appears in ultraviolet region. By addition of palladium nanoparticles to the chain, we observe a tunable red-shifting on the spectral position due to plasmonic coupling between palladium nanoparticles and a systematic spectral amplitude enhancement with the appearance of new modes of resonance.

In this paper, nesquehonite whiskers were synthesized by low-temperature aqueous solution method, and the impacts of reaction temperature, reaction time and surfactant dosage and other factors on the maximum whisker length and high aspect ratios of nesquehonite whiskers were also investigated. Results showed that under the conditions that the reaction temperature was 40 – 50 °C the reaction time was 50 – 60min and the amount of surfactant dosage was 1% (by mass), high aspect ratios nesquehonite whisker products can be synthesized. On this basis, growth mechanism of the nesquehonite whiskers was discussed.

Preliminary saturation of 2.6 nm palladium nanoparticles with hydrogen accelerates the reduction of Fe(CN)63− ions in aqueous solution three to four-fold. An analytical equation was derived describing the hydrogen saturation of palladium nanoparticles and the dependence of their catalytic activity on the hydrogen content in the metal. The specific rate constants of reduction do not depend on the content of palladium nanoparticles in the solution. A change in the temperature and pH or stirring of the solution do not affect the rate of catalytic reaction. Approaches to optimization of palladium-catalyzed reactions involving hydrogen are substantiated.
