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.

用于高效生产戊酸生物燃料的沸石定制活性位点邻近

生物燃料生产可以减轻对化石资源的依赖，从而减轻二氧化碳的排放。加氢脱氧 (HDO) 是指一系列重要的生物精炼过程来生产生物燃料。在这里，被限制在沸石 Y 微孔内的分散良好的超小 Ru 金属纳米团簇（约 1 nm）提供了所需的活性位点亲密度，这显着提高了直接生产戊酸生物燃料的化学选择性，一- 纯乙酰丙酸乙酯的锅 HDO。提高催化剂稳定性的关键是添加 La，它通过防止催化过程中沸石晶格解构来维持有限的接近。我们已经建立并扩展了对催化生物质价值化中“亲密标准”的理解。
