采用双功能磺化活性炭负载铂（Pt/AC-SO3H）催化剂，以淀粉和纤维素糖等多糖为原料，在空气条件下，在393K的水介质中采用一锅法制备葡萄糖酸。将铂浸渍在活性炭（AC）上，并对所制备的Pt/AC进行磺化反应，制备了Pt/AC- so3h。它在热水溶液中甚至包括有机酸下都具有很高的耐水性。
Gluconic acid was produced from polysaccharides, such as starch and cellobiose, in water media at 393K 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.
