Abstract Scope |
SrTiO3 is one of many photocatalysts capable of splitting water into hydrogen and oxygen in the presence of UV light. This is important because hydrogen is a possible green fuel source for the future. Molten salt synthesis of SrTiO3 from a BaTiO3 precursor has been observed to produce a SrTiO3 photocatalyst that is capable of splitting water more efficiently than SrTiO3 as purchased. The fundamental principles that allow for the observed improved efficiency are not yet known. The diffusion of atoms into and out of the titanate particles being treated gives rise to varied structure and composition radially out from the center of the catalyst particle to its surface. Therefore, this research hopes to study the interactions between the molten salt and the titanate and better understand the structure and composition of the particles is responsible for the observed improvement in water splitting ability. |
