The great efforts have been devoted to fabricate excellent hydrogenation catalysts owing to the broad applications in industrial fields. However, the preparation processes of traditional hydrogenation catalysts are often complicated. Herein, mono-valence Pt^I@COF was synthesized as a catalyst for semi-hydrogenation of phenylacetylene for the first time. The easily prepared SO₃H-linked COF possesses a two-dimensional eclipsed layered-sheet structure, making its incorporation with metal ions feasible. The as-prepared Pt^I@COF composite exhibits excellent performance for semi-hydrogenation phenylacetylene with 93.5% conversion and 90.2% selectivity to styrene under mild reaction conditions (1 bar H₂, 25 °C) within 20 min. It's worth noting that the turnover frequency (TOF) value reaches at 3965 h^-1, which outperforms most of recently reported excellent Pt-based catalysts for this reaction.

由于在工业领域中的广泛应用，已致力于制造优异的氢化催化剂。但是，传统的加氢催化剂的制备过程通常很复杂。在此，第一次合成了单价的Pt ^I @COF作为苯乙炔半加氢的催化剂。易于制备的SO ₃ H-连接的COF具有二维的月蚀层状片状结构，使其与金属离子结合成为可能。所制得的Pt ^I @COF复合材料在温和的反应条件下（1 bar H _2）具有93.5％的转化率和90.2％的苯乙烯选择性，对半氢化苯乙炔表现出优异的性能。，25°C）在20分钟内。值得注意的是，周转频率（TOF）值达到3965 h ^-1，优于最近报道的大多数用于该反应的出色的基于Pt的催化剂。
