文摘

Liquid-phase ketonization of acetic acid over three catalysts of Ru on different titania supports (anatase, rutile and P25) demonstrates the outstanding effect of the support hydrophobicity on the catalyst stability. The catalyst of Ru supported on rutile (the most hydrophobic support studied) presents the highest ketonization activity and stability. Partially hydrophobic materials can facilitate the high temperature reactions in aqueous environments for biomass conversion, environmental remediation, artificial photosynthesis and green chemistry.
