The catalytic wet air oxidation (CWAO) of cationic red GTL over the Fe2O3-CeO2-Bi2O3/γ-Al2O3 catalyst was investigated under mild operating conditions in a batch reactor. The catalyst was prepared by wet impregnation, and characterized by N2 adsorptiondesorption (BET measurement), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The effect of the reaction conditions (catalyst...

Doped Bi-based oxides were investigated as potential anode materials for direct hydrocarbon solid oxide fuel cells ~SOFCs! at intermediate temperatures. (Bi2O3)0.85(Ta2O5)0.15 met this criterion most successfully. A fraction of Bi2O3 in this material was reduced to BiO and Bi metal under fuel conditions, which yielded high conductivities ~,1 S cm! based on oxide ions and electrons above 500°C. ...

Bouquet-like hierarchical Bi2O3 photocatalyst materials with high-density surface oxygen vacancy are synthesized via a hydrothermal method by the synergetic control of NaOH and a polyvinyl alcohol (PVA) stabilizer. The OH(-) ion addition led to the formation of more relaxed PVA macromolecular clusters, as a result, a thinner PVA film was formed, the species adsorbed on the surface of the produc...

Porous Bi2O3–Bi2S3 composite sheets were constructed through a combinational methodology of chemical bath deposition and hydrothermal reaction. The Na2S precursor concentration in the solution was varied to understand correlation between vulcanization degree structure evolution porous sheets. control etching rate Bi2O3 sheet template regrowth Bi2S3 crystallites via suitable sulfide during react...

This work aimed to investigate the impact of Lead-fluoride based glasses via theoretical and simulation techniques on mechanical radiation shielding parameters. Accordingly, Bi2O3 was blended with TeO2–B2O3–PbF2 by using melt-quenching method. Using Fluka Monte Carlo code, properties have measured. Moreover, Comparatively higher density PbF80 = 6.163 g/cm3 80 mol % Bi2O3, greater µ, µm Zeff low...

Objective: This work is mainly focused to determine the antibacterial activity of green synthesized Bi2O3 nanoparticles against bacterial strains, Staphylococcus aureus and Escherichia coli using resazurin as indicator.
 Methods: Bismuth oxide were from precursor bismuth nitrate [Bi (NO3)3.5H20] by trachyspermum ammi (ajwain) seed extract. To carry out these works, NPs undergone characteri...

Upgrading of atmospheric CO2 into high-value-added acetate using renewable electricity via electrocatalysis solely remains a great challenge. Here, inspired by microbial synthesis biocatalysts, we present coupled system to produce from bridging inorganic with through formate intermediates. A 3D Bi2O3@CF integrated electrode an ice-sugar gourd shape was fabricated straightforward hydrothermal st...

Bismuth oxide kinetically stabilized by doping with a metastable structure of disordered fluorite ?-Bi2O3 has unique conductivity. Oxygen selective membranes at intermediate temperatures ~550?C, on the base cermet ?-Bi2O3/Ag, have highest potential for air separation and can be used to produce oxygen distributed multigeneration burning fossil carbon fuels. When searching optimal composition ?-B...
