The kinetically modeled results show that Mandelcorn and Steacie overestimated the rate constant of reaction (4) whereas Garcia Dominguez and Trotman-Dickenson underestimated it, and that there could be significant uncertainty in the steady-state treated results of Holt and Kerr. Reanalysis of Garcia...
在PtGCN2.5（图4）催化剂上，Pt原子位于拐角位置，在加氢过程中，C2H2首先加氢生成C2H3因此，与加氢生成CHCH3相比，C2H3加氢生成C2H4在动力学上是有利的。此外，C2H4解吸在动力学上仍优于其加氢过程。因此，PtGCN2.5催化剂拐角处的主要路线是C2H4脱附路线。图5. Pt1/Cu催化剂的C2H4、C4H6的选择性和C2H4活性以...
