Cellulosic biomass is the largest source of renewable organic carbon on our planet. Cellulose accounts for 40–50 wt % of this lignocellulose, and it is a feedstock for industrially important chemicals and fuels. The first step in cellulose conversion involves its depolymerization to glucose or to its hydrogenated product sorbitol. The hydrolysis of cellulose to glucose by homogeneous mineral acids was the subject of research for almost a century. However, homogeneous acids have significant drawbacks and are neither economical nor environmentally friendly. In 2006, our group reported for the first time the ability of heterogeneous catalysts to depolymerize cellulose through hydrolytic hydrogenation to produce sorbitol. Later, we reported the hydrolysis of cellulose to glucose using carbon catalyst containing weakly acidic functional groups. Understanding the reaction between cellulose and heterogeneous catalyst is a challenge as the reaction occurs between a solid substrate and a solid catalyst.

非均相催化剂上的纤维素解聚

纤维素生物质是地球上可再生有机碳的最大来源。纤维素占该木质纤维素的40–50 wt％，它是工业上重要的化学品和燃料的原料。纤维素转化的第一步涉及其解聚为葡萄糖或其氢化产物山梨糖醇。均质无机酸将纤维素水解为葡萄糖一直是近一个世纪的研究主题。然而，均相酸具有明显的缺点并且既不经济也不对环境友好。在2006年，我们小组首次报告了非均相催化剂通过水解加氢产生山梨糖醇来解聚纤维素的能力。后来，我们报道了使用含有弱酸性官能团的碳催化剂将纤维素水解为葡萄糖。
