摘要：

Detailed analyses have been performed for the structure of monoalkyl-monocationic surfactant stabilizing on the microscopic three-dimensional surface of the platinum nanoparticles in water, prepared by visible light-irradiation of aqueous solutions of surfactants and platinum salt, and having specific catalytic properties. C-13 NMR spectra of these colloidal dispersions in heavy water show that the surfactants stabilize the platinum nanoparticles by the hydrophobic interaction between the platinum surface and surfactant molecules, which deforms the micelle structure.
