Hydrolysis of Sugars Using Magnetic Silica Nanoparticles with Sulfonic Acid Groups

Abstract

CoFe2O4-embedded silica nanoparticles containing sulfonic acid groups were found to be highly active solid acid catalysts for hydrolysis of disaccharides (sucrose and cellobiose) and polysaccharides (starch and cellulose) with facile magnetic separation.

Hydrolysis of cellulose by sulfonated magnetic reduced graphene oxide

“…Later, other magnetic solid acids such as CoFe 2 O 4 -embedded silica nanoparticles with -SO 3 H groups, Fe 3 O 4 @C-SO 3 H and PCM-SO 3 H were reported for cellulose hydrolysis in succession. [37][38][39] To provide more candidates for the hydrolysis of cellulosic materials, more high efficiency and stability magnetic solid acids need to be developed.…”

Lignosulfonate-based heterogeneous sulfonic acid catalyst for hydrolyzing glycosidic bonds of polysaccharides

“…Acid and enzyme are among the most common catalysts for hydrolyzing cellulose into glucose [10,11]. In recent years, recyclable solid acids for cellulose hydrolysis have attracted great attentions [12][13][14][15][16][17][18][19][20][21]. However, achieving high selectivity and activity still remains a challenging task.…”

Progress in the Development of Mesoporous Solid Acid and Base Catalysts for Converting Carbohydrates into Platform Chemicals

“…Magnetic sulfonic acidfunctionalized variants of mesoporous SBA-15 silicas in which magnetic Fe 3 O 4 nanoparticles were embedded in the ordered silica matrix have been explored for the hydrolysis of cellulose (Fig. 6.26 [ 121 ], which afforded a high performance for hydrolysis of disaccharides (sucrose and cellobiose) and polysaccharides (starch and cellulose).…”
