Ba1 Ti4 O8

Ba₁Ti₄O₈ is a barium titanate-based ceramic semiconductor belonging to the perovskite family of oxides, characterized by a layered titanate structure with variable oxidation states. This compound is primarily investigated in research contexts for photocatalytic and electrochemical applications, where its semiconductor bandgap and crystal structure enable light-driven catalysis and ion transport. It represents an alternative to simpler binary titanates (like TiO₂) where barium incorporation can modulate electronic properties, band alignment, and defect chemistry for enhanced performance in energy conversion and environmental remediation.
