“…One is the breakdown stage of the cross-linking in carbon skeleton of cellulose matrix, and the other is the decomposition into small molecules. It could be explained by the catalytic properties of ZnO micro/nanoparticles, which accelerated breakdown of the cross-linking in carbon skeleton of cellulose matrix [41,42]. Notably, there was remaining undecomposed constituent in the CZ film at 1000°C and it was supposed to be ZnO inorganic micro/nanoparticles.…”

Semiconductor photocatalysts play a major role in photocatalytic process. Zinc oxide (ZnO) is supposed to be a preferred photocatalyst due to its high photosensitivity, mechanical-thermal stability, tunable morphology and non-toxicity. To enhance the photocatalytic activity of ZnO, cellulose/ZnO composite films (CZ films) with snowflake-like ZnO micro/nanoparticles immobilized in cellulose matrix were prepared by a simple dissolution and regeneration of cellulose and subsequently one-step hydrothermal synthesis of ZnO. The immobilization of ZnO was conducive to overcoming the shortcomings of aggregation easily and reclamation difficulty of scattered nanopowders. The obtained CZ films exhibited excellent photocatalytic efficiency (85.3%) to degrade methylene blue with minor amount of ZnO photocatalyst (\6 mg). The experimental results show that a photocatalytic process involving absorptiondegradation-desorption was proposed. Notably, the synergistic effects between cellulose film and the supported ZnO via absorption and desorption processes were important to enhance the photocatalytic efficiency. This work provided an effective method to support ZnO photocatalyst and improve the photocatalytic efficiency via a functional substrate.Mengya Xu and He Wang have contributed equally.

“…In addition, Bagheri et al adopted the ionic liquid 1-butyl-3-methylimidazolium chloride ([C 4 mim]Cl) for the preparation of the cellulose/ZnO nanocomposite by the microwave irradiation. [64] It was found that [C 4 mim]Cl acted as the solvent for the dissolution of cellulose and at the same time as reaction medium for the formation of ZnO nanoparticles. As described above, undoubtedly, the microwave-assisted ionic-liquid method is a rapid and effective approach for the synthesis of cellulose-based nanocomposites.…”

In recent years, the microwave-assisted ionic-liquid method has been accepted as a promising methodology for the preparation of nanomaterials and cellulose-based nanocomposites. Applications of this method in the preparation of cellulose-based nanocomposites comply with the major principles of green chemistry, that is, they use an environmentally friendly method in environmentally preferable solvents to make use of renewable materials. This minireview focuses on the recent development of the synthesis of nanomaterials and cellulose-based nanocomposites by means of the microwave-assisted ionic-liquid method. We first discuss the preparation of nanomaterials including noble metals, metal oxides, complex metal oxides, metal sulfides, and other nanomaterials by means of this method. Then we provide an overview of the synthesis of cellulose-based nanocomposites by using this method. The emphasis is on the synthesis, microstructure, and properties of nanostructured materials obtained through this methodology. Our recent research on nanomaterials and cellulose-based nanocomposites by this rapid method is summarized. In addition, the formation mechanisms involved in the microwave-assisted ionic-liquid synthesis of nanostructured materials are discussed briefly. Finally, the future perspectives of this methodology in the synthesis of nanostructured materials are proposed.

Cellulose is a linear polysaccharide and one of the world's most abundant biopolymers. It is one of the renewable biopolymers being studied to reduce the dependence on non-renewable mineral oil based products. Cellulose can be used in different kinds of composites, including the recent nanocomposites.The production of nanoscale cellulose fibers and their use in polymer composites gained increasing attention due to their interesting properties and potential applications. This review paper is trying to cover studies done to use various forms of cellulose as reinforcement for different polymers, as matrix, as reinforcement and matrix for the same nanocomposite and as a component in polyblend nanocomposites beside other polymers.
