Lignocellulosic biomass is becoming a viable alternative or complementary source for obtaining petroleum-derived products such as fuels, polymers and fine chemicals, among others. Nevertheless, the successful upgrading of lignocellulosics requires the design of efficient and robust catalysts, where sulfonated mesoporous silica materials may be an ideal choice for exploration. Herein, we have conducted the upgrading of several mono-, di- and polysaccharides such as xylose, fructose, glucose, sucrose and cellulose to valuable platform chemicals using a novel catalyst comprising sulfonated dendritic mesoporous silica nanospheres. Additionally, a thorough comparative study was conducted encompassing arrays of sulfonated silicas as catalysts with the aim of relating their activities and appreciating the features which could be responsible for their activity.

磺化树枝状介孔二氧化硅纳米球：无金属的路易斯酸催化剂，用于碳水化合物的提质

木质纤维素生物质正成为获得石油衍生产品（例如燃料，聚合物和精细化学品等）的可行替代或补充来源。然而，木质纤维素的成功升级需要设计高效且坚固的催化剂，其中磺化的中孔二氧化硅材料可能是勘探的理想选择。在这里，我们已经使用包含磺化的树枝状介孔二氧化硅纳米球的新型催化剂，将几种单糖，二糖和多糖（如木糖，果糖，葡萄糖，蔗糖和纤维素）升级为有价值的平台化学品。另外，
