摘要
Abstract It is a challenge to obtain ABO 3 perovskite oxides with favorable crystal phase and well‐defined porous structure via existing approaches. Here, we design an effective and versatile strategy to construct mesoporous ABO 3 perovskite oxides with functionalized nanocrystal frameworks and abundant oxygen vacancy sites via a resol‐assisted cationic coordinative co‐assembly approach. The as‐prepared oxygen vacancy‐rich mesoporous LaMnO 3 as heterogeneous catalyst exhibits remarkable catalytic activity and stability for hydrogenation of furfural to furfuryl alcohol, including over 99 % conversion and 96 % selectivity. Combined with density functional theory calculation, the catalytic mechanism is elucidated, revealing that porous LaMnO 3 nanocrystal framework is conducive to expose oxygen deficiency sites, which can facilitate the interaction between catalyst surface and catalytic substrate, leading to lower barrier in hydrogenation process.
