摘要：

Gluconic acid was produced from polysaccharides, such as starch and cellobiose, in water media at 393 K under air by a one-pot process using a bifunctional sulfonated activated-carbon supported platinum (Pt/AC-SO3H) catalyst. Pt/AC-SO3H was prepared by the impregnation of platinum on activated-carbon (AC) and the sulfonation of the prepared Pt/AC. It was highly water-tolerant under hot aqueous solutions even including organic acids. (C) 2010 Elsevier B.V. All rights reserved.
