Abstract:

With the aim of solving the agglomeration of traditional nano-sized photocatalysts particles that leads to low catalytic activity and recycling difficulty, it is imperative to promote the scalable application of advanced photocatalytic technology using cellulose based hybrid photocatalysts with high active site exposure, high dispersion and long-term stability. This review summarizes the recent progress in worldwide research on cellulose-based organic-inorganic photocatalysts nanohybrids. In terms of different cellulose forms, the fabrication and preparation principle of nanocellulose, cellulose-based membrane, cellulose-based aerogel and their application in the fields of water treatment are discussed. The prospect of cellulose based photocatalytic materials and the existing scientific questions and limitations are proposed. It is anticipated that this review can be used as a reference for preparation and industrialization of cellulose-based functional materials, especially in areas of environmental remediation.

Key words: cellulose-based functional material, environmental remediation, organic-inorganic nanohybrid, advanced oxidation technology, dyeing and printing wastewater treatment
