Ball milling has emerged as a powerful tool over the past few years for effecting chemical reactions by mechanical energy.Allowing a variety of reactions to occur at ambient temperatures and in solvent-free conditions, ball milling presents a greener route for many chemical processes.
This study demonstrated that liquid-nitrogen-assisted ball milling lnbm is an eective way to pretreat cellulose for increasing its conversion to value-added chemicals such as glucose and formic acid.Compared with cellulose treated with traditional single ball-milling treatment bm, lnbm-pretreated cellulose was more easily converted.
