Chementator: This graphene-based catalyst speeds cellulose saccrification, without H2SO4 waste  

| By Edited by Gerald Ondrey

In order to make ethanol from cellulose, the polysaccharide must first be broken down into sugars (saccharrified) that can be fermented. Normally, this hydrolysis reaction is catalyzed by sulfuric acid or enzymes. However, H2SO4 -based hydrolysis generates…
