Polymer-supported nanocomposites for environmental application: A review

Photocatalytic Decolorization Study of Methyl Orange by TiO₂–Chitosan Nanocomposites

“…The resulted materials are usually quite rigid, expensive and not environmentally friendly. The recent research demonstrated that biomaterials are considered as a good choice for supporting inorganic materials such as metal oxide photocatalyst, resulting in organic/inorganic hybrid and nanocomposites [10][11]. Chitosan has been reported to be one of biomaterials deemed suitable and excellent bio-matrix for the synthesis of nanosized particles or quantum dots of various inorganic photocatalysts.…”

Bimetallic Oxide Nanohybrid Synthesized from Diatom Frustules for the Removal of Selenium from Water

“…Along with the active sorbent(s), the support plays an important role. Properties like thermal, mechanical, and chemical aid in structuring of the active ingredient [24]. Consequently, composite or hybrid structures are promising materials for water treatment.…”

“…The search for more efficient water treatment media has led to the development of nanostructured adsorbents where metals, metal oxides, and ion-exchange medium are immobilized on supports that promote nanostructuring [24]. Along with the active sorbent(s), the support plays an important role.…”

Design and performance evaluation of the functional coating for air purification under indoor conditions

“…The practical use of photocatalysis seems to be far less developed than the scientific interest, as reflected by the large number of scientific publications in comparison with the limited number of products that appear in the market [7]. Several building materials have been used as carriers for the application of photocatalytic materials, for example concrete [3,10], mortar [4,11], clays [12], polymers [9,13,14], etc. It can be concluded that the application of photocatalytic materials is more beneficial while applied as a top layer rather than in the whole volume of the product, where most of the photocatalytic materials are hindered, not exposed to the environment and thus, not effective.…”

“…Based on the formation processes of the resulting composites, they could be generally divided into two categories: direct incorporation and in-situ synthesis [13]. Most of the in-situ techniques do not find the use in coatings with TiO 2 http://dx.doi.org/10.1016/j.apcatb.2014.12.012 0926-3373/© 2014 Elsevier B.V. All rights reserved.…”
