求助氢化学吸附表征的问题?求教各位朋友一个氢化学吸附的问题,就是H2-uptake例如,文献Comparative study of bimetallic Pt-Sn catalysts supported on different supports for propane dehydrogenation中使用H2-uptake表征对比了以下几种 催化剂 The measurement was determined by the pulse chemisorption technique using a conventional setup equipped with a temperature controlled setup and TCD detector. The sample (0.2 g) was reduced in flowing H2 (5 mL/min) at 500? C for 2 h, then purged in N2 at 550? C for 1 h to remove the hydrogen. The catalysts were saturated by hydrogen pulses at 30, 300, and 450? C. The pulse size was 5 mL of a 5% H2–95% N2 mixture and the time between pulses was 3 min.现在的情况是,我根据实验方案,也得到了类似的实验结果但是,审稿人却给出了如下的答复“表3的氢吸附数据存在数量级上的差错,依据催化剂的组成,消耗氢气的摩尔数是催化剂中铂含量的10倍以上,与常识不符,可能是作者把氮氢 混合气 的体积错认为是氢气的消耗体积。”求教各位,这到底是不是我实验的问题?查看更多7个回答 . 2人已关注
