Abstract
Nanoparticulate photocatalysts are a highly studied topic in the field of heterogeneous catalysis. In particular, titanium dioxide nanoparticles are considered a promising candidate for many photocatalytic and photoelectric applications. However, the size, surface structure, and crystalline morphological control of these particles is a pressing issue in the field due to the electronic structures dependence on these properties. This project analyzes the optimal synthetic conditions to generate brookite phase nanoparticles using the hydrothermal method. This project also analyzes the utilization of mineralizers to control for surface structure and particle size. The particles crystalline shape and surface structure were analyzed using powder X-ray Diffraction and Scanning Electron Microscopy. Overall, a repeatable hydrothermal method with a mono dispersion of size and control on surface structure was developed. Also in terms of mineralizer utilization, it appears that higher concentrations of mineralizer gave rise to similar morphologies as the control while lower mineralizer concentrations generated a wider variety of surface structures and sizes.
