Sulfonated magnetic carbon nanotube arrays as effective solid acid catalysts for the hydrolyses of polysaccharides in crop stalks

摘要

The sulfonated magnetic carbon nanotube arrays (MCNAs) were synthesized and characterized by electron microscopy and microanalysis technique and employed as magnetic solid acid catalysts for the hydrolyses of polysaccharides in crop stalks into sugars in present work. The results indicate that the as-prepared sulfonated MCNAs exhibited high activity and selectivity, excellent magnetic property and stability, showing a good potential application for effective hydrolyses of polysaccharides in crop stalks in the future.
