Guanfeng Liang, Limin He, Prof. Masahiko Arai and Prof. Fengyu Zhao The Pt-Enriched PtNi Alloy Surface and its Excellent Catalytic Performance in Hydrolytic Hydrogenation of Cellulose ChemSusChem 7
Put a Pt on it: ZSM-5-supported PtNi alloy particles with Pt-enriched alloy surface are prepared and characterized. The Pt-enriched alloy surface enhances hydrogenation activity but suppresses hydrogenolysis activity, thus resulting in high yield of hexitols. The decoration with an alloy surface offers a new approach to prevent the rapid deactivation of Ni-based catalysts in hot-compressed water.
