  Polyacrylate-Assisted Size Control of Silver Nanoparticles and Their Catalytic Activity

  摘要：

  In this work, a simple one-step method of silver nanoparticle (NPs) preparation with controlled size is introduced. Silver NPs were prepared by reduction of [Ag(NH3)(2)](+) complex cation by D-maltose in the presence of low concentrations (1 x 10(-10) mol/L to 1 x 10(-7) mol/L) of high-molecular-weight poly(acrylic acid) (PAA). This modification of the reduction reaction results in managing of the prepared silver nanoparticles size in the range from 28 nm (the reaction system without PAA) to 77 nm (system with the highest used PAA concentration). The presence of poly(acrylic acid) influences both nucleation process and also the subsequent stage of nanoparticle growth. The rate of nuclei formation by homogeneous nucleation is affected by PAA due to the formation of the strong complex with silver ions which results in a prolongation of the initiation phase of the reduction process proportionally to PAA concentration. The formation of the adsorption layer of PAA on the surface of the emerging silver nuclei prevents the direct contact between silver ions and nuclei, which is necessary for continuation of the nuclei growth via heterogeneous catalytical mechanism. Because of this restriction, the silver nuclei grow up to their final size by the aggregation mechanism. The as-prepared silver NPs were tested as efficient catalysts for redox reactions. For this purpose, a model reaction, the reduction of organic dye by sodium borohydride was used. The mechanism of this reaction is discussed using the Langmuir-Hinshelwood model of heterogeneous catalysis.

  under visible-light irradiation (>400 nm). The results show clearly that the BiVO4 /Ag composite microspheres possess a much higher photocatalytic activity than pure BiVO4 microspheres and P25. In addition, Raman analyses show that the BiVO4 /Ag composite microspheres exhibit an excellent surface-enhanced Raman scattering (SERS) performance.
