مستخلص: Mixed metal oxyhalides are an exciting class of photocatalysts, capable of the sustainable generation of fuels and remediation of pollutants with solar energy. Bismuth oxyhalides of the types Bi 4 MO 8 X (M = Nb and Ta; X = Cl and Br) and Bi 2 AO 4 X (A = most lanthanides; X = Cl, Br, and I) have an electronic structure that imparts photostability, as their valence band maxima (VBM) are composed of O 2p orbitals rather than X n p orbitals that typify many other bismuth oxyhalides. Here, flux-based synthesis of intergrowth Bi 4 NbO 8 Cl-Bi 2 GdO 4 Cl is reported, testing the hypothesis that both intergrowth stoichiometry and M identity serve as levers toward tunable optoelectronic properties. X-ray scattering and atomically resolved electron microscopy verify intergrowth formation. Facile manipulation of the Bi 4 NbO 8 Cl-to-Bi 2 GdO 4 Cl ratio is achieved with the specific ratio influencing both the crystal and electronic structures of the intergrowths. This compositional flexibility and crystal structure engineering can be leveraged for photocatalytic applications, with comparisons to the previously reported Bi 4 TaO 8 Cl-Bi 2 GdO 4 Cl intergrowth revealing how subtle structural and compositional features can impact photocatalytic materials.
