Asymmetric α/β-Ga <sub>2</sub> O <sub>3</sub> hetero-phase junction for enhanced piezoelectric catalysis
This communication describes the design of a highly active prismatic Ga<sub>2</sub>O<sub>3</sub> piezocatalyst. A unique α/β-Ga<sub>2</sub>O<sub>3</sub> hetero-phase junction was formed by the temperature-induced transformation between the α phase and β phase of Ga<sub>2</sub>O<sub>3</sub>, which could break the coordination symmetry and simultaneously change the energy band structure, leading to a boosted displacement current and electron transfer under ultrasonic vibration.
