Effect of BallMilling Pretreatment of Cellulose on Its Photoreforming ...

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 ...
