Bioethanol Production from Unpretreated Cellulose under Neutral Selfsustainable Hydrolysis/Hydrogenolysis Conditions Promoted by the Heterogeneous Pd/Fe(3)O(4) Catalyst

[Image: see text] The direct conversion of untreated microcrystalline cellulose into C(2)–C(3) alcohols, through a one-pot process promoted by the heterogeneous bimetallic Pd/Fe(3)O(4) catalyst, is presented. The process is selfsustainable without the addition of external molecular hydrogen or acid/...

description [Image: see text] The direct conversion of untreated microcrystalline cellulose into C(2)–C(3) alcohols, through a one-pot process promoted by the heterogeneous bimetallic Pd/Fe(3)O(4) catalyst, is presented. The process is selfsustainable without the addition of external molecular hydrogen or acid/basic promoters and is mainly selective toward ethanol. At 240 °C, a complete cellulose conversion was reached after 12 h with an ethanol molar selectivity of 51% among liquid products. The synergistic effect played by water (which aids in the chemical pretreatment means of cellulose through the hydrolysis process) and the Pd/Fe(3)O(4) catalyst (which catalyzes the hydrogenolysis reaction driving the pattern of obtained products) is elucidated.
