In summary, we revealed a dome-shaped superconducting _T_c(P) in the R-I phase of ReO3 over a wide pressure range of 12–39 GPa, and the maximum _T_c ≈ 17.8 K sets a record of high-T_c among 5_d transition-metal oxides. The enhancement of N(E_F) originating from enhanced Re-O hybridizations and the phonon modes associated with close-packed oxygen sublattice are essential to the emergence of superconductivity. The present study demonstrates that the synergistic effect between extended 5_d orbitals of Re and the light element O mediates superconductivity in ReO3. The present work provides important clues for exploring new high-T_c superconductors in 5_d transition-metal-oxides via high-pressure study or heterostructure engineering and also offers a new route for designing high-_T_c superconductors in oxygen-rich systems.
