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

Abstract

The construction of heterojunction between semiconductor is an effective technology to enhance its photocatalytic activity using solar energy. In this paper, a series of BiPO 4 /Bi 2 MoO 6 heterostructures with different mole ratio of Mo:P were successfully synthesized via one-pot solvothermal method. Photocatalytic activity of all samples were investigated by degrading methylene blue (MB) under visible light. Among the catalysts, BMoP-1-3 sample with oxygen vacancy has excellent photocatalytic activity due to improving its light harvesting and charge separation by establishment of Z-scheme system heterostructure, which is 1.65 and 1.22 times that of pure BiPO 4 and Bi 2 MoO 6 , respectively.

Designing Nanosheet Heterostructures of CuO Grown on Bi2MoO6 as a Photoelectrochemical Biosensor for Detecting Alpha‐Fetoprotein

“…The O 1s peaks centered at 529.7 eV, 531.7 eV, and 533.2 eV in Figure 1d are attributed to oxygen [30] . The Mo 3d XPS spectrum of the 5 %‐BM‐160 sample showed two strong peaks at 231.7 and 234.9 eV (see Figure 1e), which were assigned to Mo 3d 5/2 and Mo 3d 3/2 of Mo 6+ [31] . The ability of this material to absorb visible light was tested using UV‐Vis DRS (see Figure S1).…”

CuO, BM, and CuO/BM-5 % demonstrated very strong visible light absorption: CuO in the 200-800 nm range, while BM and CuO/BM-5 % absorbed only from 400-700 nm range.…”

New Aptamer/MoS2/Ni-Fe LDH Photoelectric Sensor for Bisphenol A Determination

“…More BPA encouraged the development of aptamer–BPA complexes, which reduced the photocurrent. The BPA concentration can be measured by monitoring the decrease of photocurrent density ( Scheme 1 ) [ 37 , 41 ]. The above characteristics indicate that the MoS 2 /LDH-5% PEC aptasensor can be used to detect BPA.…”

Bismuth-Based Z-Scheme Heterojunction Photocatalysts for Remediation of Contaminated Water

“…A series of BiPO 4 /Bi 2 MoO 6 Z-scheme heterostructures were successfully synthesized by a one-pot solvothermal method. 91 A solution combustion method is a chemical synthesis method of nanostructured materials. It is an exothermic reaction mechanism in which the precursor and solvents are mixed at the molecular level to form a solid-phase product.…”
