“…Synthetic analogs of the grandreefite structure are observed also among selenates ([Pb2F2]SeO4 [34] and [Ln2O2]SeO4, Ln = La, Pr, Nd [35]) and chromates ([La2O2]CrO4 [32]). The same structure was also established for [Bi2O2]SO4 [36] and some rare-earth oxysulfates [Ln2O2]SO4 (La [29], Sm [30] and Eu [31]). In the meantime, a different atomic arrangement was suggested for [Nd2O2]SO4 [37].…”

“…2021664. [36], indexing the powder patters was not straightforward as two sets of Miller indices are possible for the strongest reflections yielding two alternative unit cells which led to close residuals upon LeBail full-pattern decomposition. The correct ones, listed in Table 1, were chosen based on results of Rietveld analysis wherein the derived atomic arrangements (with the structure of [Eu 2 O 2 ]SO 4 [31] taken as the initial model) were chemically sensible.…”

“…Structurally related architectures occur when the interlayer gallery hosts various molecular anions (linear triatomic [20,21], trigonal [22][23][24][25][26], or tetrahedral [27][28][29][30][31][32][33][34][35][36][37][38] (Figure 1a-h). There are three possible orientations of tetrahedral anions between the litharge slabs (Figure 1d-f) two of which are represented in nature by the mineral grandreefite [Pb 2 F 2 ]SO 4 [27] and a slag phase [Ba 2 F 2 ]S 2 O 3 [28].…”

During the last decades, layered structures have attracted particular and increasing interest due to the multitude of outstanding properties exhibited by their representatives. Particularly common among their archetypes, with a significant number of mineral and synthetic species structural derivatives, is that of litharge. In the current paper, we report the structural studies of two later rare-earth oxysulfates, [Ln2O2]SO4 (Ln = Dy, Ho), which belong indeed to the grandreefite family, and a novel compound [Bi2CuO3]SO4, which belongs to a new structure type and demonstrates the second example of Cu2+ incorporation into litharge-type slabs. Crystals of [Bi2CuO3]SO4 were obtained under high-pressure/high-temperature (HP/HT) conditions, whereas polycrystalline samples of [Ln2O2]SO4 (Ln = Dy, Ho) compounds were prepared via an exchange solid-state reaction. The crystal structure of [Bi2CuO3]SO4 is based on alternation of continuous [Bi2CuO3]2+ layers of edge-sharing OBi2Cu2 and OBi3Cu tetrahedra and sheets of sulfate groups. Cu2+ cations are in cis position in O5Bi2Cu2 and O6Bi2Cu2 oxocentered tetrahedra in litharge slab. The crystal structure of [Ln2O2]SO4 (Ln = Dy, Ho) is completely analogous to those of grandreefite and oxysulfates of La, Sm, Eu, and Bi.

“…Bismuth oxysulfate (Bi 2 O 2 SO 4 , BOS) owns a layered structure similar to BOC, and is stacked by [Bi 2 O 2 ] 2+ layer and [SO 4 ] 2− layer. [ 21 ] However, its transformation under CO 2 RR conditions is rarely reported. Herein, we have synthesized the BOS nanoparticles (NPs) as a pre‐catalyst to achieve reconstructed BOC R nanosheets (NSs) for CO 2 RR by electrochemical in situ anion exchange.…”

Electrochemical reduction of CO2 (CO2RR) into value‐added products is a promising strategy to reduce energy consumption and solve environmental issues. Formic acid/formate is one of the high‐value, easy‐to‐collect, and economically viable products. Herein, the reconstructed Bi2O2CO3 nanosheets (BOCR NSs) are synthesized by an in situ electrochemical anion exchange strategy from Bi2O2SO4 as a pre‐catalyst. The BOCR NSs achieve a high formate Faradaic efficiency (FEformate) of 95.7% at −1.1 V versus reversible hydrogen electrode (vs. RHE), and maintain FEformate above 90% in a wide potential range from −0.8 to −1.5 V in H‐cell. The in situ spectroscopic studies reveal that the obtained BOCR NSs undergo the anion exchange from Bi2O2SO4 to Bi2O2CO3 and further promote the self‐reduction to metallic Bi to construct Bi/BiO active site to facilitate the formation of OCHO* intermediate. This result demonstrates anion exchange strategy can be used to rational design high performance of the catalysts toward CO2RR.
