This MQP investigated a method for fixing TiO2 onto glass beads for use in a photocatalytic reactor. It was found that the apparent rate constant for the degradation of methylene blue using a single layer of the glass beads was 0.003 min-1 and that the apparent rate constant for three to four layers of the beads was 0.0065 min-1. This indicates the possibility of UV transmissibility through the beads and suggests that they may be a better substrate for the photocatalyst than other available substrates. The rate constants determined in this MQP were comparable to those found by others. These results indicate that glass beads are a very effective substrate for fixing a photocatalyst.
