3 mmol of Bi(NO3)3·5H2O was dissolved in 20 mL mixed solution of ethanol and glycerol (the volume ratio of ethanol to glycerol was 1:1) and stirred for 10 min. The morphology and element composition of the samples The morphology and element composition of the samples can be analyzed by...
0.728 g of Bi(NO3)3·5H2O and 0.144 g of citric acid were dissolved in 30 ml 1.6 M HNO3 solution with accompanying stirring for 30 min. The solution was adjusted pH Results and discussion In this study, the molar ratio of β-Bi2O3 and the Bismuth source was fixed firstly, the effec...
Such a hierarchical Bi2O3-Bi2S3 nanostructure can be employed as efficient electrode material for Li storage, due to the high surface areas, rich porosity and unique heterogeneous phase. The electrochemical results show that the heterostructure exhibits a high Coulombic efficiency (83.7%), stable ...
were dissolved in dilute nit ric acid to prepare a nitrate solution containing a total metal ion (B 3+ ,Y 3+ ) concentration of 0.1 mol/ L. In order to prevent agglomeration, 3 wt. % PEG4000 (polyethylene glycol of average molecular weight equal to 4000) ...
In a typical operation, 0.35 mmol cetyltrimethyl ammonium bromide (CTAB, Sinopharm Chemicals) and 1.0 mmol thioacetamide (TAA, Sinopharm Chemicals) was dissolved in 40 ml water by sonication for 15 min. Then to this solution a 0.5 mmol Bi(NO3)3?5H2O (in 5 ml of 0.4 M HNO3) was added...
[30]. The O 1sspectrum can also be deconvoluted into two peaks at 528 eV and 529.3 eV, which are ascribed to Bi–O in BiOBr and Bi–O in Bi2O3[31]. Finally, the slight shift to lower binding energy of the two peaks in the Br 3dspectrum at 66.6 eV and 68.7 eV ascribed to ...
The present invention discloses a magnetic visible Catalyst Preparation and Application of Fe3O4 @ Bi2O3-BiOBr-BiOI, the catalyst is prepared as follows: (1) the Bi (NO3) 3 · 5H2O dissolved in a mixture of ethylene glycol is stirred with ethanol solvent to form a solution; take out ...
[18]. Later, formazan crystals were solubilized in an aqueous solution of 20% SDS dissolved in 50% dimethylformamide. Briefly, 2 × 104cells were seeded in each well of a 96-well plate and treated the next day. After a 24 h exposure period, cells were added with filtered MTT solution ...
Melamine was directly polymerized at 500 °C for 4 h and 520 °C for 2 h in order to prepare g-C3N4. A stoichiometric quantity of Bi(NO3) and melamine was first dissolved in 10 mL CH3OH to synthesis the Bi2O3/g-C3N4nanocomposite. After stirring for two hours, the homogenous suspensio...
(468 nm) than bare Bi2O3 NPs, as can be seen in Fig.4a. This suggests the nanocomposite material has intimate mixing of the component materials likely contributes to the observed improvements in optical properties due to the synergistic effect than individual oxide components. Therefore, the ...
