Novel pure α-, β-, and mixed-phase α/β-Bi2O3 photocatalysts for enhanced organic dye degradation under both visible light and solar irradiation

Fuel‐dependent, shape‐selective, distinct blue and green photoluminescence from α‐Bi2O3 and β‐Bi2O3 synthesised using microwave combustion

“…The O1s peak at 529.2 eV can be attributed to Bi 2 O 3 [15]. The peaks at 530.4 and 530.7 eV suggest the presence of adsorbed oxygen [15,46]. The O1s peak at 531.5 eV can be attributed to the adsorbed -OH species on the surface [24].…”

Sunlight driven isotropic β-Bi2O3 with high charge-carrier mobility for the efficient degradation of bisphenol A and phenol

“…23–27 Hollow and porous microspheres of β-Bi 2 O 3 were obtained through a template-free hydrothermal method, a template-free solvothermal method, a hydrothermal synthesis method with subsequent calcination, and a thermal decomposition approach. 28–32 Nanosheets of β-Bi 2 O 3 were acquired by a hydrothermal–calcination method and a precipitation–calcination method. 33–37 Moreover, nanoparticles, nanowires, elliptical shapes, cubic shapes, dumbbell-like shapes, and flower-like shapes of β-Bi 2 O 3 were also acquired via different synthesis methods.…”

High concentration of methyl orange elimination by targeted construction of an α-Bi2O3/Ph–CC–Cu Z-scheme

“…4(D). The peaks at 164.9 and 159.7 eV in the spectrum are a result of the Bi4f 5/2 and Bi4f 7/2 orbitals of Bi 3+ in α-Bi 2 O 3 , 21 indicating the existence of α-Bi 2 O 3 in 10% α-Bi 2 O 3 /Ph–CC–Cu hybrid.…”
