2023年8月1日 · TEM images revealed the formation of Bi 2 O 3 nanoparticles with an average size of 5.0 nm and an interplanar distance d120, characteristic of cubic Bi 2 O 3. EDX analyses showed the presence of Bi, O and S precursor chemical elements of Bi 2 O 3 and Bi 2 S 3 NCs. SAED patterns showed the formation of the cubic crystalline structure of Bi 2 O 3 ...

3 天之前 · The S-scheme Bi2O3/MnS heterojunction is fabricated by loading Bi2O3 onto the MnS surface by solvothermal method. The XRD detection demonstrates that the crystalline structure of MnS remains unaltered after loading Bi2O3. SEM and TEM tests revealed that Bi2O3 is uniformly loaded on the MnS surface and tightly bound to it, forming an S-scheme heterojunction. The heterojunction both boosts the ...

2022年9月30日 · In this research, Na 3 Ni 2 BiO 6 was exfoliated with acid and water to obtain β -Bi 2 O 3 nanosheets less than 10 nm in height and over 1 µ m in lateral size. Our results open the possibility for further exploring β -Bi 2 O 3 nanosheets to determine whether their properties change from the bulk to the nanoscale.
