Here, a sustainable esterification strategy of cellulose was developed to efficiently synthesize cellulose oleate (COE) by ball milling to endow cellulose with thermoplasticity. In this strategy, a low dosage of oleic acid (6 mol per anhydroglucose) and no solvent were used to achieve the goal during the ballmilling process. According to ...

Photoreforming of cellulose is a promising route for sustainable H2 production. Herein, ballmilling (BM, with varied treatment times of h) was employed to pretreat microcrystalline cellulose (MCC) to improve its activity in photoreforming over a Pt/TiO2 catalyst. It was found that BM treatment reduced the particle size, crystallinity index (CrI), and degree of polymerization (DP) of ...
