Abstract

The properties of a new catalytic Pt/N-graphene system in the gas-phase reaction of formic acid decomposition for the production of pure hydrogen were studied. Graphene powders undoped and doped with nitrogen atoms were used as carbon supports. Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscopy (TEM), and the chemisorption of CO were used to characterize the synthesized catalysts. It was found that the activity of the catalysts increased upon graphene doping with nitrogen atoms and with increasing the platinum concentration from 0.2 to 1 wt %; the catalyst selectivity in the test reaction was as high as 96–99%.

Pt/N-石墨烯上甲酸的分解

摘要

研究了一种新的催化 Pt/N-石墨烯体系在甲酸分解气相反应生产纯氢中的性能。未掺杂和掺杂有氮原子的石墨烯粉末用作碳载体。拉曼光谱、X 射线光电子能谱 (XPS)、高分辨率透射电子显微镜 (TEM) 和 CO 的化学吸附用​​于表征合成的催化剂。结果表明，石墨烯掺杂氮原子和铂浓度从 0.2% 增加到 1% 时，催化剂的活性增加；测试反应中的催化剂选择性高达 96-99%。
