生物燃料生产可以减轻对化石资源的依赖，从而减少二氧化碳排放。加氢脱氧（HDO）是指生产生物燃料的一系列重要的生物精炼过程。在这里，良好分散和超小Ru金属纳米团簇（约。1 nm），限制在沸石Y的微孔内，提供了所需的活性位点紧密性，这显著提高了在纯乙酰丙酸乙酯的直接一锅HDO中生产戊酸生物燃料的化学选择性。提高催化剂稳定性的关键是添加La，其通过防止催化过程中沸石晶格解构来维持受限邻近。我们已经建立并扩展了对催化生物质定价中的"亲密标准"的理解。这些发现带来了新的理解，HDO反应在有限的接近网站，导致潜在的应用戊酸生物燃料在生物质转化。
Biofuel production can alleviate reliance on fossil resources and thus carbon dioxide emission. Hydrodeoxygenation (HDO) refers collectively to a series of important biorefinery processes to produce biofuels. Here, well-dispersed and ultra-small Ru metal nanoclusters (ca. 1 nm), confined within the micropores of zeolite Y, provide the required active site intimacy, which significantly boosts the chemoselectivity towards the production of pentanoic biofuels in the direct, one-pot HDO of neat ethyl levulinate. Crucial for improving catalyst stability is the addition of La, which upholds the confined proximity by preventing zeolite lattice deconstruction during catalysis. We have established and extended an understanding of the "intimacy criterion" in catalytic biomass valorization. These findings bring new understanding of HDO reactions over confined proximity sites, leading to potential application for pentanoic biofuels in biomass conversion.
