Abstract

Recent progress on preparation of TiO2/adsorbent nanocomposites (TNC) via wet chemical impregnation has been reviewed. The potential applications of TNC are growing continuously and the material is very likely to find its place in future applications of wastewater treatment. In a TNC preparation via wet chemical impregnation, electronic properties (i.e. amount of charger carrier and its lifetime) and morphological properties (i.e. particle size, surface area and crystal phase) of TiO2 in as-prepared resultants are sensitively dependent on the experimental conditions during the synthesis. Currently, one major limitation in this promising area is that visible-light capacity has yet to be introduced into TNC systems. It is envisaged that this could be realized via a single wet chemical procedure without significant increase of the process complexity.
