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

• The sulfonated MCNAs are prepared for hydrolyses of polysaccharides in crop stalks.
• The sulfonated MCNAs show excellent magnetic properties and stability.
• The sulfonated MCNAs exhibit comparable catalytic activity to H2SO4.

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.

The sulfonated magnetic carbon nanotube arrays prepared and used as the magnetic solid acid catalysts for the hydrolyses of polysaccharides in crop stalks, exhibit much 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.Figure optionsDownload as PowerPoint slide
