N2 - Transition Metal Oxide (TMO) has emerged recently as a promising material for Oxygen Evolution Reaction (OER), especially for Perovskite Oxide due to its catalytic activity and abundance in nature. In this work, Barium Titanate Oxygen-deficiency (BTO) (BaTiO3-x) has been synthesized with a sol-gel method followed by a variation of sintering period to discover an effect to the formation of oxygen vacancies related to the optical bandgap. This review is started to proof the formation of barium titanate oxygen-deficiency with TGA and DSC to understand the thermal habit of BTO formation, then using FTIR and Raman to understand any remain organic compound and any kind of configuration BTO formed, and UV-Vis to understand the bandgap of BTO as a function to reduce the activation energy. The results showed that by varying the sintering period (0, 2, 4, and 8 hours) has made a significant difference to the formed BTO and also the optical bandgap.
