Grey SrCu2O2 with vacancy and pore structure: Dual organic degradation properties and first-principles calculations
A novel SrCu□O□ photocatalyst containing Cu vacancy and O vacancy was synthesized for the first time based on solid-phase sintering. The crystal structure, elemental composition, microscopic morphology, optical properties and energy band structure of the samples were characterized and analyzed in detail. The vacancies in the material were determined by ICP-MS and EPR, first-principles calculations showed that the introduction of vacancies extends the forbidden band of the photocatalytic to the visible band. The photocatalytic performance of SrCu□O□ was evaluated by degrading MB and TC HCI. Our results show that SrCu□O□ enhances the degradation performance of organic compounds due to rich vacancies that promote electron-hole pair separation and improve photogenerated carrier separation efficiency. Vacancy-containing metal oxide catalysts have broad application value in environmental remediation.
