“…Earlier, Hwang et al (2004 found that the compounds with the -OH groups enhance tungsten oxide photochromism. Adachi et al (2012) confirmed this conclusion on the example of cellulose; photoreduction preferentially occurs for W 6? ions in the WO 3 matrix, which are bonded to the cellulose substrate via -OH hydrogen bonds.…”

Reversible photochromic hybrid organicinorganic films containing nanocrystalline cellulose as a matrix and tungsten oxide as a photochromic component (CNC/WO 3 ) were obtained via a simple and quick solvent casting method. The films were studied by scanning electron microscopy, together with element mapping, FT-IR spectroscopy and X-ray diffraction, confirming successful incorporation of WO 3 nanoparticles into a nanocellulose matrix.Thermal analysis data indicated that the modification of a nanocellulose matrix with WO 3 increases its thermal stability. The CNC/WO 3 films showed a quick coloration-bleaching transition with good reversibility within 20 min, without notable degradation of photochromic properties after 10 cycles. The synthetic method proposed allows for scalable preparation of highly efficient low-cost WO 3 -based photochromic materials.

Metal oxide can be prepared by mineralization process of biopolymers like cellulose, starch, alginate, chitosan, chitin, carrageenan, dextran, DNA, pectin, collagen, gelatin, silk, lignin and white-egg. The formation of corresponding hybrid composite [metal oxide@biopolymer] allows mastering the morphology, porosity, composition and structure of metal oxide and also gives access to [metal oxide@carbon] composite upon carbonization of the biopolymer We briefly review the recent advances in this fields in order to show the diversity of the approaches and their adaptations to produce material with potential applications in catalysis, energy and environment.
