| Description | Journal: Iop Conference Series: Materials Science and Engineering The photocatalytic degradation of methylene blue (MB) of the geopolymer paste with addition nanoparticles titanium dioxide $(TiO_{2}$) was investigated under illumination of sunlight radiation. In this work, $TiO_{2}$-based geopolymer paste was prepare by dry mixing of Class F fly ash (FA) and different amount of $nano-TiO_{2}$ (0, 2.5, 5.0, 10.0 & 15.0 wt%). Then, the alkali activator, which is combination of sodium hydroxide solution with sodium silicate was added to the dry mix $FA-TiO_{2}$ with ratio of 2.5. All the sample was cured at room temperature and aged for 28 days. The photocatalytic behaviour of $nano-TiO_{2}$ was evaluated and compared through photocatalytic testing and surface degradation testing by measuring the photodegradation of MB under sunlight rays. The experimental results revealed that the addition of $nano-TiO_{2}$ to the geopolymer paste shows excellent result on photocatalytic degradation of MB after exposure to sunlight up to 150 minutes. |
