Under the current situation of the exhausting non-renewable resources such as coal, oil and natural gas, many efforts have been directed at extending the utilization of renewable resources for new energy and new materials [1,2]. Cellulose, natural polymer from the cell wall of green plants with the formula of (C6 H10 O5 )n , is the most abundant renewable resources on earth [3,4]. It exists not only in various plants, but also in some organisms such as bacteria and animals. The unique chemical and physical properties of cellulose make it being a biomass resource for many decades, and will still be an indispensable raw material for papermaking, food, and additives in optical and pharmaceutical industries [5].
