Effective catalytic conversion of cellulose pyrolysis into D-Allose via Al1-Fe5 nano-catalysts

This research has made significant advancements in the field of high-value bio-oil production, specifically focusing on the synthesis of the rare sugar D-Allose. Notably, synthesizing D-Allose through cellulose pyrolysis has long been challenging due to its high synthetic difficulty, which has limited related studies. By employing a one-pot synthesis approach using Al x -Fe y nano-catalysts prepared through a unique cellulose pretreatment method, this experiment successfully achieved efficient generation of D-Allose during rapid pyrolysis. Systematic experimentation demonstrated that at 330 °C with the Al 1 -Fe 5 nano-catalyst, the yield of D-Allose from cellulose pyrolysis reached an impressive 50.69 %, accompanied by a detection of 14.35 % furfural in the bio-oil. This breakthrough not only significantly contributes to the high-value utilization of bio-oil but also provides robust support for further development in this area. Simultaneously, the success of this research extends beyond high-value bio-oil utilization and makes a substantial impact on both the scientific community and industry.
