SAPO-5 zeolite supported RuMn was a highly efficient catalyst for the aqueous-phase selective hydrodeoxygenation of guaiacol to cyclohexanol. The optimal catalyst achieved a high cyclohexanol yield of 93.7% at full guaiacol conversion under mild conditions, with a high TOF of 920 h -1 . Moreover, the catalyst displayed remarkable performance for the hydrogenation of phenol to cyclohexanol, where a 100% yield of cyclohexanol was obtained at a phenol-to-Ru molar ratio of about 17900. In particular, the catalyst exhibited excellent recyclability and could be recycled for 20 times without obvious activity loss. The as-prepared RuMn/SAPO-5 catalyst exhibited higher performance than most of the reported Ru-based catalysts.
