Preparation Functionalized Graphene Aerogels as Air Cleaner Filter

In order to improve indoor environment, new technologies for air purifying is needed to overcome the drawbacks of current air cleaners in the market. The combination of adsorption and photocatalysis is definitely a competitive and applicable way of air cleaning. The adsorbents could concentrate the pollutants around TiO2 to facilitate the photocatalytic reaction, while the photocatalytic oxidation serves as a regeneration way of the adsorbents. This study developed a hybrid material of graphene aerogels and titanium dioxide, which is named functionalized graphene. It is designed to be the key materials in an air cleaner. XRD, SEM, BET had been used to investigate its structural properties. (C) 2015 The Authors. Published by Elsevier Ltd.
