Photocatalytic water splitting and CO2 reduction offer sustainable solutions to energy environmental issues, but efficient semiconductor photocatalysts are still limited. Oxide with d0 and/or d10 metals often have wide bandgaps, incorporating d10ns2 can raise the valence band maximum (VBM) narrow bandgap. Here, we synthesized BiTi4GaO11 (BTGO), a new photocatalyst containing d106s2, d0, metals. Structural analysis via powder X-ray neutron diffraction confirmed BTGO crystallizes in space group Cmcm, Ga cooccupying all three Ti sites. Density functional theory calculations revealed that conduction minimum (CBM) of is primarily composed t2g - O 2p antibonding orbitals. Hybridization between Bi 6s orbitals leads formation orbitals, which further interact 6p form VBM. This interaction shifts VBM upward, narrows bandgap (Eg = 2.82 eV), enables visible-light absorption. Experimental results demonstrated efficiently catalyzes photocatalytic H2 production reduction. Furthermore, incorporation cocatalysts suppressed recombination photogenerated charge carriers, enhancing activity. work highlights importance electronic structure bonding understanding fundamental mechanisms photocatalysis.
