Enhanced photocatalytic activity of TiO2/Ca12Al14O33 in NO removal

Abstract
TiO2 supported on Ca12Al14O33 (Mayenite) was synthesized and investigated for use as a photocatalytic concrete material. TiO2/Mayenite (TiO2/M) catalysts were prepared with varying TiO2 loading amounts (1-20 wt%). The
photocatalytic activity of the catalysts was measured using the ISO standard NO removal test. TiO2/M catalysts exhibited significantly enhanced photocatalytic activities compared to pure TiO2, with the NO removal efficiency increasing
as TiO2 loading increased up to 10 wt% and then decreasing with further loading of TiO2. The NO removal rate of the
TiO2/M catalyst, which contained 10 wt% TiO2, was 8.72 mol (equivalent to 350 mol/m2
∙h). X-ray photoelectron
spectroscopy (XPS) analysis suggested that oxygen on the TiO2/M catalysts with low TiO2 loading exists in the form of
Ti-OH rather than TiO2. This study focuses on the formation of Ti-OH on the catalyst surface, which is promoted by
the unique crystal structure of Mayenite that supplies oxygen ions and electrons to the TiO2 layer. The NO removal
efficiency of the catalysts was found to be dependent on the interaction between TiO2 and Mayenite. Overall, this study
demonstrates the potential of TiO2/Mayenite for use as a highly effective photocatalytic concrete material, with the
unique properties of the Mayenite support playing a critical role in enhancing the photocatalytic activity of the catalyst
