摘要

α，β-不饱和醛在金属氧化物催化剂上催化加氢制α，β-不饱和醇具有潜在的工业应用前景。在此，我们开发了一种Ni/f-Al2O3催化剂，该催化剂由原子分散的Niδ+ (2 < δ < 3)物质组成，在多孔的叶状Al2O3上，从糠醛（FFR）的CTH中获得了>； 97%的糠醇（FOL）收率，转换频率（TOF）为216 h−1。最重要的是，该催化剂可以循环使用至少6次而不明显失去活性。其优异的催化性能可归因于Ni/f-Al2O3表面丰富而稳定的Niδ+型酸碱对。

Construction of Atomically Dispersed Niδ+ Species on Leaf-like Al2O3 for Selective Transfer Hydrogenation of Furfural

Catalytic transfer hydrogenation (CTH) of α,β-unsaturated aldehydes to α,β-unsaturated alcohols over metal oxide catalysts is of potential for industrial application. Herein, we have developed a Ni/f-Al₂O₃ catalyst comprising atomically dispersed Ni^δ+ (2 < δ < 3) species on porous leaf-like Al₂O₃, over which a > 97% yield of furfuryl alcohol (FOL) from CTH of furfural (FFR) is obtained with a turnover frequency (TOF) of 216 h^− 1. Most importantly, the catalyst can be recycled at least 6 times without obvious loss of activity. Its superior catalytic performance can be attributed to the abundant and stable Ni^δ+-type acid-base pairs on the surface of Ni/f-Al₂O₃.

期刊介绍： Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
