FORMATION OF A POLYMER-PROTECTED PLATINUM SOL - A NEW UNDERSTANDING OF THE PARAMETERS CONTROLLING MORPHOLOGY
The formation of platinum sols (〈d〉 = 1.5-4 nm) in a methanol-water mixture by methanol reduction of ionic platinum in the presence of steric stabilizer poly(vinylpyrrolidone) has been studied by transmission electron microscopy and UV-visible spectrophotometry. A high concentration of chloride ions...
