【Abstract】 A new method for the preparation of Pt/carbonaceous resin catalyst with high degree of metal dispersion and high mechanical strength is described in this paper.The results abtained by using this catalyst for the microd.eterminatioll of organic oxygen in coulometrlc method are satisfactory. Besides, the characteristics of catal lyst, the distribution of Pt particles and surface micloscopic shape on this catalyst were studied preliminarily.更多还原
