Hydrogenation of α,β‐unsaturated aldehydes to unsaturated alcohols suffers a huge challenge in chemoselectivity. Herein, surface decoration by FeO_x is introduced to remarkably improve the selectivity of cinnamyl alcohol (COL) in cinnamaldehyde (CAL) hydrogenation on Pt/MoO_3−y. The enhanced acidity on Pt–FeO_x interfaces is beneficial for the chemisorption and activation of C=O bonds, promoting selective hydrogenation. The optimal catalysts with defined FeO_x decoration afford efficient and chemoselective CAL hydrogenation (91.3 % selectivity) under mild conditions (P_H2=1 MPa, T=30 °C). Moreover, such innovation is further extended to develop other efficient metal (Ir, Rh and Pd) catalysts, identifying a universal promotion to Pt‐group metals. This work is anticipated to inspire the rational design of high‐performance catalysts via effective surface/interface engineering.

氧化铁修饰的Pt / MoO3-y催化剂上肉桂醛的化学选择性加氢

α，β-不饱和醛加氢成不饱和醇在化学选择性方面面临巨大挑战。在此，引入了通过FeO _x进行的表面装饰，以显着提高肉桂醇（COL）在Pt / MoO _3-y上的肉桂醛（CAL）加氢中的选择性。Pt–FeO _x界面上增强的酸度有利于C = O键的化学吸附和活化，从而促进选择性氢化。具有确定的FeO _x修饰的最佳催化剂可在温和条件下（P _H2 = 1 MPa，T =30°C）。此外，这种创新进一步扩展到开发其他有效的金属（Ir，Rh和Pd）催化剂，确定了对Pt类金属的普遍推广。预期这项工作将通过有效的表面/界面工程激发高性能催化剂的合理设计。
