Description
Titanium dioxide (TiO2) is a photocatalytic material which has made its way into the European market for use within building materials (e.g. in photocatalytic cement). The air-cleaning and self-cleaning properties of TiO2 make it an attractive material for development. TiO2 has been widely studied to determine the mechanism by which it catalyzes reactions, but research into its use in photocatalytic cement has focused only on the percent pollutant removed and not the composition of the resulting gas. The current research focuses on examining the oxidation of methanol over the solid materials and the development of a methodology to study the formation of intermediates in the removal of the pollutant molecule. The initial methanol oxidation studies over the photocatalytic cement resulted in a reduction in the concentration of methanol and an increase in potential products. However, these studies identified several system challenges that led to a focus on the system design. It is recommended that future reactor systems optimize the transfer of material through the use of agitation and minimize the path length between the reactor cell and the FTIR gas cell. Furthermore, creating an air-tight system is paramount to the success of future studies.
