Abstract

A easy-to-handle and bi-functional solid water-tolerant catalyst with the balance of Brønsted acid site ( BAS) and Lewis acid site (LAS) is crucial for the efficient conversion of glucose into 5-hydroxymethylfurfural (HMF). In the work, the AACH@γ-AlOOH (designated as N_y@γ-AlOOH) catalysts were synthesized through the in-situ AACH substitution of γ-AlOOH, where the AlO₆ octahedral units served as the wate - tolerant LAS with mild acid strength, while the unsaturated AlO₅ pentahedral units acted as the weak BAS, together forming Lewis - Brønsted acid pairs at molecular- level proximity. Glucose turnover and HMF selectivity were enhanced due to the rapid fructose transfer from LAS to the adjacent BAS for its dehydration to HMF, facilitating LAS liberation for another glucose turnover. Under an optimized catalyst N_4/11@γ-AlOOH, a high HMF yield of 73.8 % was obtained in biphasic system of 1-butanol / H₂O - NaCl (20 wt%) at 140 °C for 3 h.

期刊介绍： Applied Catalysis A: General publishes original papers on all aspects of catalysis of basic and practical interest to chemical scientists in both industrial and academic fields, with an emphasis onnew understanding of catalysts and catalytic reactions, new catalytic materials, new techniques, and new processes, especially those that have potential practical implications. Papers that report results of a thorough study or optimization of systems or processes that are well understood, widely studied, or minor variations of known ones are discouraged. Authors should include statements in a separate section "Justification for Publication" of how the manuscript fits the scope of the journal in the cover letter to the editors. Submissions without such justification will be rejected without review.
