Abstract
(type = abstract)
Photocatalytic hydrogen production by water splitting has been widely studied as one of the promising solutions for energy and environment problems. Perovskite alkaline earth metal titanates are capable of splitting water and producing hydrogen due to their electrical, optical, catalytic properties. Calcium titanate is one of the promising semiconductors because of its wide band gap and its high stability against photo-corrosion in acidic and wet environments. This research focuses on the investigation of the photocatalytic activity for hydrogen generation using metallic silver loaded on calcium titanate in the presence of a sacrificial electronic donor, glycerol, and under UV and visible light. Nanocrystalline CaTiO3 showed photocatalytic activity under UV light due to charge transfer from the semiconductor to the metal, and this process was proved using photoluminescence spectroscopy. The characterizations of nanocrystalline calcium titanate were conducted using Raman, UV-vis diffuse reflectance, and photoluminescence spectroscopy. In this research, we have also investigated the capability of metallic silver deposited on mesoporous calcium titanate to decompose water and produce hydrogen under UV light without a sacrificial organic donor. Further, by using emission and synchronous photoluminescence spectroscopy, we studied the midgap states within the forbidden gap in the semiconductor, and the effect of humidification on these midgap states.
