Development of TiO-CaCO Based Composites as an Affordable Building Material for the Photocatalytic Abatement of Hazardous NO from the Environment.

This study explores the depollution activity of a photocatalytic cementitious composite comprising various compositions of n-TiO and CaCO. The photocatalytic activity of the CaCO-TiO composite material is assessed for the aqueous photodegradation efficiency of MB dye solution and NO under UV light exposure. The catalyst CaCO-TiO exhibits the importance of an optimal balance between CaCO and n-TiO for the highest NO removal of 60% and MB dye removal of 74.

Facile and Simple Post Treatment Ball Milling Strategy for the Production of Low-Cost TiO Composites with Enhanced Photocatalytic Performance and Applicability to Construction Materials.

A facile and cost-effective approach assisted by ball milling (BM) of commercial titanium dioxide (TiO), has been utilized to develop cheaper and efficient construction materials. At least three of the commercial and cheaper TiO samples (BA01-01, BA01-01+ and R996, designated as A1, A4 and R1, respectively) were selected and subjected to BM treatment to enhance their photocatalytic efficiencies, if possible. It was noted, that the samples A1, A4 and R1 were typical composites of TiO and calcium carbonate (CaCO) and contained varying proportions of anatase, and rutile phases of TiO and CaCO.
