Ionic liquids as a class of promising solvents have attracted much attention in recent years. Cellulose is the most abundant bio-renewable resource in the world and would be the most promising feedstock for industry in the future. Dissolution of cellulose in ionic liquids combines two major green chemistry principles, using environmentally preferable solvents and bio-renewable feedstocks, and has opened a novel platform for the green utilization of cellulose materials. The progress in dissolution of cellulose with ionic liquids and its application for the preparation of regenerated cellulose composites, cellulose derivatives, and bio-ethanol are reviewed. More scrutinized studies on the fundamentals, such as the mechanism of dissolution and degradation of cellulose macromolecules, transformation of cellulose crystalline structure, and the homogeneous chemical modification of cellulose with solid reagents, have to be further investigated to develop new bio-polymers and prosper the industry.
