Cowlesite is a Calcium Aluminum silicate CaAl2Si3O106H2O which formed under the hydrothermal conditions of low temperature (1800C) and pressure (1.013250bar). Cowlesite minerals are known for their peculiar occurrence. Synthesis of Cowlesite mineral was carried by suitable stoichiometric composition. Hydrothermal synthesized Cowlesite mineral was characterized by XRD, SEM, and EDAX. It crystallized in the orthorhombic system and a lattice parameter a=23.22Å, b=30.58Å, c=25.01Å, Volume of Unit cell=17758.79Å3, α=β=γ=900. EDAX results show the elemental concentration of raw material which was used.
In this study, Zn-doped calcium silicate (Zn-WO) materials were successfully synthesized. As precursors, Ca (OH)2, SiO2, and ZnO were utilized, then the hydrothermal experiment was conducted for 6 hours at 1050°C. In this work, the behavior of two groups of raw materials exposed to isobaric and different temperature circumstances is described. The synthesized sample was examined using XRD, SEM, EDAX, Raman, BET, and UV-Vis spectroscopic techniques to understand the adsorbent's physicochemical characteristics, and the adsorbent's performance was evaluated. The energy band gap of 2.70 eV and 2.62 eV with the surface area calculated by BET of 92.4 m2/g and 112.6 m2/g for Zn-WO-1 and Zn-WO-2 respectively were found in this research. After 150 minutes of Zn-WO-1 and Zn-WO-2, the maximum amount of degradation by absorption under dark and sunlight photocatalytic activity compared with the two synthesized samples, 88.4% and 92.3% of methylene blue and 80.9% and 85.3% of methyl orange, took place.
