Photocatalytic degradation of benzene over different morphology BiPO4: Revealing the significant contribution of high–energy facets and oxygen vacancies

Oxygen Vacant Semiconductor Photocatalysts

“…Thus, an outstanding photocatalytic degradation activity for gaseous benzene was achieved. [152] Different from the metal oxides whose VB is composed of O 2p orbital, the VB of bismuth-based semiconductors generally consists of O 2p and Bi 6s hybrid orbitals, always leading to a reduced band gap. Therefore, the OVs engineer on bismuthbased semiconductors is more prone to manipulate the band structure for better making use of solar energy.…”

One‐Step Solvothermal Synthesis of BiPO4/Bi2MoO6 Heterostructure with Oxygen Vacancies and Z‐Scheme System for Enhanced Photocatalytic Performance

“…As shown in the Mo 3d spectra (Figure c), two peaks located at 231.7 and 234.8 eV, are corresponding to 3d 5/2 and 3d 3/2 of Mo 6+ , respectively . The peak at 132.6 eV (Figure d) can be indexed to P 5+ of the PO 4 3− . Figure e shows the three typical peaks at 530.3, 532.4 and 535.0 eV, which can be ascribed to the lattice O in BiPO 4 , the lattice O in Bi 2 MoO 6 and the surface‐adsorbed O species, respectively.…”

BiPO4‐Derived 2D Nanosheets for Efficient Electrocatalytic Reduction of CO2 to Liquid Fuel

“…[13] Moreover, Xray photoelectron spectroscopy (XPS) analysis confirms the BiPO 4 -1 pre-catalyst is BiPO 4 ( Figure S4). [14] BiPO 4 is stable under ambient conditions but tends to reduce to metallic Bi during cathodic reduction. We loaded the as-prepared BiPO 4 samples onto carbon paper as the working electrodes.…”
