Bamboo carbon-based solid acid was prepared via sulfuric acid impregnation

carbonization and sulfonation with cellulose-rich bamboo powder as feedstock

and its application in cellulose hydrolysis was studied. Firstly

the results obtained by TG of raw and modified bamboo powders and their main components showed that sulfuric acid had significant effects on breaking the chemical bonds in bamboo power to promote the pyrolysis and carbonization processes at lower temperature. The systematically research was conducted on the impregnation ratio

impregnation concentration

carbonization temperature and sulfonation temperature

which strongly affected the catalytic properties of bamboo carbon-based solid acid. Then

the optimal preparation conditions were obtained. Finally

the bamboo carbon-based solid acid was characterized by XRD

BET

FT-IR and SEM. These results indicated that the bamboo carbon-based solid catalyst had a favourable textile structure and considerable sulfonic acid content

showing that the sulfonic acid content was related to the number of active hydrogen on the aromatic carbon.
