中文摘要the organic sol method for preparing ultrafine transition metal colloid particles reported for the first time by bonnemann et al. [h. bonnemann, w brijoux, r. brinkmann, e. dinjus, t. jou beta en, b. korall, angew. chem. int. ed. engl., 30 (1991) 1312] has been improved in this paper. the improved organic sol method uses sncl2 as the reductant and methanol as the organic solvent. thus, this method is very simple and inexpensive. it was found that the average size of the pt particles in the pt/c catalysts can be controlled by adjusting the evaporating temperature of the solvent. therefore, the pt/c catalysts prepared by the same method are suitable for evaluating the size effect of the pt particles on electrocatalytic performance for methanol oxidation. the results of the x-ray diffraction (xrd) and transmission electron microscopy (tem) showed that when the evaporating temperatures of the solvent are 65, 60, 50, 40, and 30 degrees c, the average sizes of the pt particles in the pt/c catalysts prepared are: 2.2, 3.2, 3.8, 4.3, and 4.8 nm, respectively. the x-ray photoelectron spectroscopic (xps) results demonstrated that the small pt particles are easily oxidized and the decomposition/adsorption of methanol cannot proceed on the surfaces of pt oxides.
