| 摘 要： | 采用盐酸、柠檬酸为竞争吸附剂,通过在一定范围内调节竞争吸附剂浓度可以得到Pt蛋壳型、蛋白型、蛋黄型、均匀型分布催化剂。通过对制备的各种Pt分布催化剂的氢氧滴定表征(TPT),证明合金Pt与合金Sn存在关联,为Pt-Sn/Al2O3催化剂中存在PtSn合金提供了依据。

| Abstract: | The catalysts with different Pt distribution types,such as eggshell type,egg white type,egg yolk type and uniform type,could be prepared by using hydrochloric acid or citric acid as a competitive adsorbent and regulating its concentration within a certain range.Adopted H2-O2 titration method to characterize the catalysts with different Pt distributions,the results showed that there is a correlation between Pt alloys and Sn alloys,which proved that Platinum-tin alloys existing in Pt-Sn/Al2O3 catalysts. |
