Synthesis of basic bismuth(III) oxalate by precipitation from nitrate solutions

High purity β-Bi2O3preparation by thermal decomposition of tartrates

“…This work continues our previous research on the preparation of bismuth compounds with optically active and inactive isomers of oxyacids [25]. This direction in bismuth chemistry is poorly studied.…”

Thermal transformations of bismuth (III) tartrates

“…Thus, in the thermal decomposition of tartrates of alkaline-earth [30] and rareearth elements [31] the formation of metal oxalates as intermediate products with their subsequent transformation into carbonates and corresponding oxides was indicated. In our study of oxidative thermolysis process of the bismuth tartrate, based on the XRD data, the formation of bismuth oxalate with the proposed composition BiC2O4(OH) [32]…”

Carbon Dioxide Anion Radicals Assisted Highly Efficient Photocatalytic H2O2 Production over Bi(C2O4)OH

“…30 This originated from the self-oxidation of C 2 O 4 2− and then the release of CO 2 , leading to the carbonation of the materials. 31 In the Raman spectra (Figure 2d), the band intensity corresponding to the vibrations of Bi−O, C−C, and COO − all increased after the reaction in OA solution, 29 while decreasing after the reaction in the absence of OA. Given that Bi 0 was generated on the photocatalysts surface after light irradiation, as demonstrated by UV−vis DRS, the surfaceenhanced Raman scattering (SERS) could be taken into account.…”

“…Fourier transform infrared (FT-IR) spectroscopy was employed to study the change in function groups in the materials (Figure 2c). When Bi(C 2 O 4 )OH reacted with OA, the intensity of C 2 O 4 2− related peaks 29 remained unchanged. The peaks at 503 and 446 cm −1 were identified as the stretching vibration of the Bi−O bonds.…”

“…The peaks at 503 and 446 cm −1 were identified as the stretching vibration of the Bi−O bonds. 29 Whereas when Bi(C 2 O 4 )OH reacted in deionized water, all of the peak intensity obviously diminished, and a new sharp peak at 845 cm −1 appeared, implicating the formation of carbonate groups (CO 3…”
