Check Digit Verification of cas no

The CAS Registry Mumber 12048-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,4 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12048-50:
(7*1)+(6*2)+(5*0)+(4*4)+(3*8)+(2*5)+(1*0)=69
69 % 10 = 9
So 12048-50-9 is a valid CAS Registry Number.

Preparation and Photoconductivity of Films of Bi2O3-MO3 (M equals Mo, or W) Obtained by Rapid Quenching.

Sekiya,Tsuzuki,Torii

, p. 601 - 608 (1986)

The Bi//2O//3-MO//3 films (M equals Mo or W) were prepared by a rapid quenching technique using a twin-roller type equipment. The quenched films containing from 2. 5 to 5 mol% MO//3 or WO//3 precipitated only a tetragonal phase. By further increase of these oxide additives, a cubic phase ( delta -phase) was formed coexisting with the tetragonal one. The lowest content of the additives to form singly the delta -phase was 12. 5% for MoO//3// and 10% for WO//3 respectively. The quenched films were characterized by a high photoconductivity. The highest photoconductivity appeared when a beam of about 500 nm in wavelength was irradiated on the film. The photoconduction was observed in all films containing less than 12. 5% additives.

Monoclinic dibismuth tetraoxide (m-Bi2O4) for piezocatalysis: new use for neglected materials

Liu, Fengling,Chen, Haoxuan,Xu, Chenmin,Wang, Linlin,Qiu, Pengxiang,Gao, Shuo,Zhu, Jiawei,Zhang, Shuai,Guo, Zhaobing

, p. 2740 - 2743 (2021)

Piezocatalysis is a promising approach for environmental pollutant removal. Monoclinic dibismuth tetraoxide (m-Bi2O4) was first applied to piezocatalyze organics under ultrasonic vibration. The built-in electric field with ultrasonic stress drives the separation of holes and electrons inm-Bi2O4. Its excellent piezocatalytic activity, reusability and chemical stability makem-Bi2O4a new candidate of piezocatalysis.

B4O7, the first defined binary bismuth(III,V) oxide

Begemann,Jansen

, p. 123 - 135 (1989)

The thermal decomposition of both amorphous and crystalline bismuth (III, V) oxide hydrates has been investigated by applying a high oxygen pressure p02 up to 400 MPa, and the products were characterized by X-ray powder techniques. Two of the obtained pure bismuth(III, V) oxide phases derive from the CaF2-type structure with the unit cell dimensions a = 553.90(5) pm and a = 547.54(3) pm. The X-ray diffraction studies do not indicate any significant homogeneity range with respect to the oxygen content. Bi4O7, which is reported for the first time, only forms at high oxygen pressures. The X-ray powder diffraction diagram indicates a triclinic pyrochlore structure.

Preparation of bismuth oxides with mixed valence from hydrated sodium bismuth oxide

Kinomura, Nobukazu,Kumada, Nobuhiro

, p. 129 - 134 (1995)

Hydrothermal treatment up to 200°C of the hydrated sodium bismuth oxide, NaBiO3·nH2O, resulted in the formation of some bismuth oxides. The major phase is α-Bi2O3 above 190°C, a bismuth oxide with mixed valence around 160°C and monoclinic Bi2O4 around 140°C. Monoclinic Bi2O4 is a new bismuth oxide with mixed valence, Bi3+Bi5+O4, isostructural with β-Sb2O4. Its lattice parameters are a = 12.2668(2), b = 5.1180(1), c = 5.5670(1)angstrom and β = 107.838(1)° in the monoclinic system. Both bismuth oxides containing Bi5+ change to α-Bi2O3 on heating in air at 600°C, accompanied by weight loss caused by reduction of Bi5+ to Bi3+, monoclinic Bi2O4 via an intermediate phase during the course of pyrolysis.

The boosted photocatalytic activity over perylene diimide modified Bi2O4 hybrid photocatalyst with internal electric field

Zhang, Xiaoli,Shi, Lei,Yao, Lizhu,Cui, Lishuang

, (2021/10/12)

In this paper, an organic-inorganic perylene diimide modified Bi2O4 (PDI/Bi2O4) composite photocatalyst was successfully prepared. Its apparent morphology, chemical structure, element composition and chemical state were measured through XRD, XPS, TEM and DRS. It is observed that because of formed an internal electric field, PDI nanorods are well attached to the surface of Bi2O4 nanorods, and a compact interfacial contact is formed, which greatly accelerates the migration rate of photogenerated carriers. When the PDI/Bi2O4 composite photocatalyst was used to degrade Rhodamine B, the reaction rate was 0.169 min-1, which was 7.3 folds more than Bi2O4, and could maintain 80% after three times recycling experiments. Then, combined with the electronic band structure of PDI and Bi2O4, type Ⅱ photocatalytic mechanism is speculated.
