Flame Spray Pyrolysis Synthesis of Vo-Rich Nano-SrTiO_3-x.

ABSTRACT: Engineering of oxygen vacancies (Vo) in nanomaterials allows diligent control of their physicochemical properties. SrTiO₃ possesses the typical ABO₃ structure and has attracted considerable attention among the titanates due to its chemical stability and its high conduction band energy. This has resulted in its extensive use in photocatalytic energy-related processes, among others. Herein, we introduce the use of Flame Spray Pyrolysis (FSP); an industrial and scalable process to produce Vo-rich SrTiO₃ perovskites. We present two types of Anoxic Flame Spray Pyrolysis (A-FSP) technologies using CH₄ gas as a reducing source: Radial A-FSP (RA-FSP); and Axial A-FSP (AA-FSP). These are used for the control engineering of oxygen vacancies in the SrTiO
