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 ...
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...
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) ...
(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 ...
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 ...

To obtain NiCo2O4, 2 mmol NiCl2·6H2O, 4 mmol CoCl2·6H2O, 1 mmol cetyltrimethylammonium bromide (CTAB), and 18 mmol urea were dissolved in 60 mL deionized water, forming a homogeneous pink solution. Next, the solution was placed on Teflon coated stainless steel and maintained at a temp...
The stoichiometry of phase-pure pyrochlores was determined via inductively coupled plasma optical emission spectroscopy (PerkinElmer ICP-OES, Optima DV 2000) using triplicate samples (0.1 g dissolved in 250 ml of 5% HNO3 and HF). The thermal stability of phase-pure BMT pyrochlores was investigated ...
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...
