1High-silica faujasite zeolite-tailored metal encapsulation for the low-temperature production of pentanoic biofuels显示文摘Zeolite-encapsulated metal nanoclusters are at the heart of bifunctional catalysts,which hold great potential for petrochemical conversion and the emerging sustainable biorefineries.Nevertheless,efficient encapsulation of metal nanoclusters into a high-silica zeolite Y in particular with good structural integrity still remains a significant challenge.Herein,we have constructed Ru nanoclusters(~1 nm)encapsulated inside a high-silica zeolite Y(SY)with a SiO_(2)/Al_(2)O_(3) ratio(SAR)of 10 via a cooperative strategy for direct zeolite synthesis and a consecutive impregnation for metal encapsulation.Compared with the benchmark Ru/H-USY and other analogues,the as-prepared Ru/H-SY markedly boosts the yields of pentanoic biofuels and stability in the direct hydrodeoxygenation of biomass-derived levulinate even at a mild temperature of 180℃,which are attributed to the notable stabilization of transition states by the enhanced acid accessibility and properly sized constraints of zeolite cavities owing to the good structural integrity.Wenhao Cui Yuanshuai Liu Pengfei Guo Zhijie Wu Liqun Kang Huawei Geng Shengqi Chu Linying Wang Dong Fan Zhenghao Jia Haifeng Qi Wenhao Luo Peng Tian Zhongmin Liu 2024Journal of Energy Chemistry2024,88,1:0
