2-D Heterometallic Pb-Iodoargentate Framework [PbAg2I6]n with a Diskoid [Pb(18-crown-6)]2+ Linker and Cocatalyst for Synergistically Enhanced Photocatalytic Properties via g-C3N4 Doping

The heterometallic Pb-iodoargentate hybrid [Pb(18-crown-6)(PbAg₂I₆)]_n (1; 18-crown-6 = 1,4,7,10,13,16-hexaoxacyclooctadecane) was prepared via self-assembly of the tetrahedal AgI₄ and octahedral PbI₆ primary units using crown ether 18-crown-6 as an organic ligand in DMF solvent. The hybrid heterocomposite cocatalyst based on 1 and graphitic carbon nitride (g-C₃N₄) was prepared by a facile solvothermal method. In 1, the dimeric units Ag₂I₆ and Pb₂I₁₀ are joined via face sharing, leading to a ternary heterometallic 1-D [PbAg₂I₆^2-]_n chain containing novel Ag₂Pb₂I₄ cubes. The 1-D chains are joined by the discoid [Pb(18-crown-6)]²⁺ complex cations, forming the 2-D [Pb(18-crown-6)(PbAg₂I₆)]_n hybrid with the skeleton of [Pb₂Ag₂I₆]_n. Compound 1 shows photocatalytic activity in the degradation of MB at room temperature under visible-light irradiation. The photoelectric response measurement showed that the photocurrent of 1 increased from 1.41 to 2.43 μA/cm^-2 when g-C₃N₄ was loaded, indicating that the introduction of a certain amount of g-C₃N₄ on the surface of 1 improves the separation and migration rate of photoinduced electrons and holes. The 1/g-C₃N₄ composite showed much higher photocatalytic efficiency in comparison to pristine 1 and g-C₃N₄ for MB degradation, which suggests the synergistic effect between 1 and g-C₃N₄ toward visible-light-driven photocatalytic performance. Meanwhile, the 1/g-C₃N₄ composite exhibited good reusability and stability in the photocatalytic reaction. Free radical quenching experiments showed that the ^•O₂^- radical is the main reactive substance over catalyst 1, while h⁺, ^•OH, and ^•O₂^- species have synergistic effects over the 1/g-C₃N₄ composite catalyst in the process of photodegradation.

We report the synthesis of a series of AAg(m)I(n) single-crystals within 24 h, at room temperature, utilizing AgI nanoparticles (NPs) as the precursor. The AgI NPs impart high reactivity under mild conditions and favor the growth kinetics. 0D, 1D and 2D iodoargentate crystals can be obtained. This work represents the first application of NPs in the field of organo-metal-halide crystals and will inspire the design of other AM(m)X(n) crystals.
