The Cover Feature shows a highly efficient and stable Ru/ZSM-5 catalyst for levulinic acid hydrogenation in water, which can be recycled at least 10 times (conv.>95%, yield>85%). In their Full Paper, B. Zhang et al. demonstrate that the excellent stability is a result of the higher content of tetrahedrally-coordinated Al and the preferable pore connectivity in well-crystallized ZSM-5. The tetrahedral-coordinated framework Al proved extremely helpful for the formation of strong metal–support interactions, which suppressed Ru aggregation and leaching in the acidic environment. Besides, the low pore volume and connectivity in ZSM-5 significantly inhibited the formation of carbonaceous residues on the surface and channels. More information can be found in the Full Paper by B. Zhang et al. on page 3646 in Issue 19, 2017 (DOI: 10.1002/cctc.201700664).
