Abstract
ABSTRACTA new type of eco-friendly CaWO4/CSH (calcium silicate hydrate) nanocomposite was firstly synthesized by the reaction of ammonium metatungstate and alkali-activated granulated blast furnace slag-based gelled material. The XRD and FESEM results showed that the CaWO4/CSH nanocomposite was composed of CaWO4 crystal phase and calcium silicate hydrate (CSH). The pore size distribution result indicated that the 5CaWO4/CSH nanocomposite held the highest mesopore volume percentage of 94.17%. The 5CaWO4/CSH nanocomposite exhibited the highest degradation rate of 90.29%. The photocatalytic degradation reaction of basic violet 5BN dye belonged to the second-order reaction kinetics. The excellent photocatalytic activity of 5CaWO4/CSH nanocomposite was attributed to the synergistic effect of the active phase of CaWO4 and the mesopore structure of CSH.
