hnsc: 金币+30, ★★★很有帮助, 我已从别的渠道找到Pd/C的测试条件,文献催化剂组分和含量和我完全一样,多谢 2015-11-17 21:45:15
Applied Catalysis B: Environmental, Volume 127, 30 October 2012, Pages 212-220
MWCNTs supported PtSb alloy nanoparticles,

The dispersion of Pt was calculated on the basis of CO adsorption. Sample (0.15 g) was first pretreated in hydrogen (50 cm3/min) at 150 °C for 1 h and purged with helium (50 cm3/min) for 1 h at the same temperature. And then, 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.
