Abstract

The air pollution inside a building has become a big problem for a modern society that people spend most of their days inside. In this paper, We tried to resolve the problem by developing a photocatalysts highly active inside. A photocatalyst is in fact not suitable for indoor use because it only reacts under strong ultraviolet rays in general. Furthermore, the price of such photocatalysts is still highly expensive to adopt in massive quantity for an indoor finishing material even though it has been priced down from number of studies operated until present. In order to solve problems, the attempts to bring out the certain level of reactions even under weak level of ultraviolet rays by adding Ni and Zn, the transition elements were made in this examination. Moreover, KA100 that is fairly economical among commercialized products is used as a precursor to lower the price and improved the characteristics of photocatalysts through a simple process of heating. Therefore, the experiments were varied with different rates of adding Ni and Zn to KA100 and temperatures for the combination of a photocatalysts and transition elements.
