| 英文摘要 | A green synthetic strategy to prepare monodisperse pt nanoparticles was reported. aminodextran acted as the reductive and protective agents, and pt nanoparticles were characterized by uv/vis spectroscopy (uv-vis), pt nanoparticles were conveniently obtained at one step. transmission electron microscopy (tem), fourier transform infrared spectroscopy (ft-ir), and x-ray photoelectron spectroscopy (xps). by changing the initial molar ratio of arninodextran to platinum precursor, pt nanoparticles with different size were obtained. amino groups of aminodextran could absorb on pt nanoparticles surfaces and serve as a very good stabilizer. however, dextran without amino groups could not effectively stabilize pt nanoparticles and aggregation of pt nanoparticles were obtained. catalytic activity of these pt nanoparticles for the electron-transfer reaction between hexacyanoferrate (iii) ions and thiosulfate ions was also studied, and they showed good catalytic efficiency.
