Abstract

A catalytic composite material containing highly conductive Super P carbon black and platinum nanoparticles has been prepared by the liquid-phase synthesis method and studied. An increase in electroactivity of Pt nanoparticles in the presence of highly conductive carbon black has been revealed in comparison with the reference sample, platinized carbon black E-teK, where the carbon material was Vulcan XC-72 carbon black. The nature of the carbon material has been shown to affect the catalytic activity of platinum nanoparticles. The value of the electrochemically active surface area of the developed catalytic material and the catalytic material based on the Etek catalyst has been determined by cyclic voltammetry to be 54 and 20 m²/g, respectively.

摘要

通过液相合成方法制备了含有高导电性Super P炭黑和铂纳米颗粒的催化复合材料，并进行了研究。与参考样品镀铂炭黑E-teK（碳材料为Vulcan XC-72炭黑）相比，在高导电炭黑存在下Pt纳米颗粒的电活性有所提高。已经显示碳材料的性质影响铂纳米颗粒的催化活性。通过循环伏安法测定，所开发的催化材料和基于Etek催化剂的催化材料的电化学活性表面积的值分别为54和20m ² / g。
