Application of molecular dynamic energy of kaolin clay as photocatalysts

Photocatalysts generated from biomaterials have the advantage of being environmentally friendly, offering a beneficial role in the photocatalysis of water splitting. To overcome the absorption of photocatalysts in a certain light wavelength range, this study utilizes kaolin clay as a photocatalyst. This study estimated the molecular dynamic energy and molecular interaction of the kaolin clay and greywater photocatalyst by Hyperchem Software. In the simulation process, it is assumed that gray water was filtered into clean water (H2O). From the performed simulations, kaolin clay provides a significant role as a photocatalyst, evidenced when the amount of water was constantly maintained; if the number of kaolin molecules increases, the molecular dynamic energy tends to significantly increase by 52.5646 kcal/mol to 172,913 kcal/mol. However, when the number of kaolin clay molecules was constantly maintained and the number of water molecules increased, the molecular dynamic energy did not significantly increase, indicating that during the photocatalytic process, the appropriate ratio of kaolin clay and water is required to produce the maximum photocatalytic reaction.
