The Synthesis Of Functionalized-Silica/Carbon Catalysts From Rice Husk For The Conversion Of Hexose Sugar Into Methyl Levulinate And 5-Hydroxymethylfurfural

Recently, silica/carbon composite material has received much attention in heterogeneous catalysis due to its unique hybrid properties. However, the difficulties in designing green synthetic methods remain challenging. In this study, varied proportion of silica/carbon heterogeneous catalyst was prepa...
