金属分散度的测量？ 有人问过这个问题！可以检索一下！我转抄一下！氢气吸附一般适用于镍\钴等,但是不适合于贵金属及铜, 因为后者易发生氢溢流, 误差很大!贵金属多采用co吸附！catalysis communications, volume 10, issue 12, 25 june 2009, pages 1586-1590applied catalysis b: environmental, volume 127, 30 october 2012, pages 212-220铜的分散度测定最有效的是n2o氧化，fe的分散度估计很难，因为它很难被还原到金属态！n2o氧化测铜的分散度很技术成熟、也最为全世界的研究者认可！journal of catalysis, volume 296, december 2012, pages 1-11fuel, volume 96, june 2012, pages 419-425applied catalysis a: general, volume 403, issues 1–2, 22 august 2011, pages 173-182applied catalysis b: environmental, volume 101, issues 3–4, 14 january 2011, pages 431-440（hottes 25 papers of the journal）室温下氢的吸附在镍上多数都是不可逆的，关键是co吸附在pt上，有大量可逆吸附！所以测定的技巧需要锻炼！所以文献中常有这样的话the catalyst was cooled to room temperature and co pulses were injected from a calibrated on-line sampling valve. co adsorption was assumed to be completed after three successive peaks showed the same peak areas. a co/pt stoichiometry of 1 was used for calculations.catalysis communications, volume 10, issue 12, 25 june 2009, pages 1586-1590applied catalysis b: environmental, volume 127, 30 october 2012, pages 212-220， 查看更多
