More Greasy, more selective: amine-capped Pt(3)Co nanocatalysts were synthesized and used for the hydrogenation of cinnamaldehyde (CAL). Capping the catalysts with amines that contain long carbon chains results in an ordered surface "array", in which high selectivity towards C=O hydrogenation can be achieved because the C=C bond in CAL does not interact with the surface. The longer the carbon chains in the amine, the higher the selectivity.
更多的油脂，更多的选择性：胺封端的 Pt(3)Co 纳米催化剂被合成并用于肉桂醛（CAL）的加氢。用含有长碳链的胺封端催化剂会导致表面有序“排列”，从而可以实现对 C=O 加氢的高选择性，因为 CAL 中的 C=C 键不会与表面相互作用。胺中的碳链越长，选择性越高。
