The non-catalytic hydrosilylation reaction has much high activation energy due to large differences in the energy of HOMO-LUMO pairing and restriction of the orbital symmetry overlap. For Pt(0)-catalytic hydrosilylation, the electronic structure of Me₃SiH has been modified by the oxidative addition of Pt(0). It not only narrows down the energy differences between the bonding orbitals but also improves the orbital overlap symmetry, leading to the effective decrease of the activation energy. The trouble for the Pt(0)-catalytic hydrosilylation is the formation of the majority of the Pt-containing intermediates. Because they are fallen into the deep potential-energy, the reductive eliminations are energetically prohibitive, which is the essence of Pt-contamination. The reductive elimination can be achieved with the ligand exchange method, and the energy barrier can be tuned by suitable ligands.

由于HOMO-LUMO配对能量的巨大差异和轨道对称重叠的限制，非催化氢化硅烷化反应具有很高的活化能。对于 Pt(0)-催化氢化硅烷化，Me _{3的电子结构}SiH 已通过氧化添加 Pt(0) 进行了改性。它不仅缩小了键合轨道之间的能量差异，而且改善了轨道重叠对称性，导致活化能有效降低。Pt(0) 催化氢化硅烷化的问题是形成了大多数含 Pt 的中间体。因为它们落入深层势能中，所以还原消除在能量上是禁止的，这就是Pt污染的本质。可以通过配体交换方法实现还原消除，并且可以通过合适的配体来调节能垒。
