The traditional methods for creating oxygen vacancies in materials present several challenges and limitations, such as high preparation temperatures, limited vacancy generation, morphological destruction, which hinder the application of transition metal oxides field zinc–air batteries (ZABs). In order to address these we have introduced a pioneering lithium reduction strategy generating δ-MnO2@MXene composite materials. This stands out its simplicity implementation, applicability at room temperature, preservation material's structural integrity. research demonstrates that aqueous Ov-MnO2@MXene-5, with vacancies, exhibits an outstanding reaction (ORR) activity ORR half-wave potential reaching 0.787 V. DFT calculations demonstrated enhanced could be attributed adjustments electronic structure alterations adsorption bond lengths. These result from introduction turn promote electron transport catalytic activity. context batteries, cells Ov-MnO2@MXene-5 air cathode exhibit performance, featuring significantly improved maximum power density (198.3 mW cm–2) long-term cycling stability. Through innovative introducing this study has successfully electrochemical performance MnO2, overcoming limitations associated vacancies. Consequently, opens up new avenues directions nonprecious catalyst ZABs.
