Constructing a novel hierarchical β-Ag2MoO4/BiVO4 photocatalyst with Z-scheme heterojunction utilizing Ag as an electron mediator

Preparation and study of Z-type heterojunction composite photocatalytic material with Ag2MoO4 modified rosette-like Bi2WO6 with Ag-SPR promoting effect

“…It can be seen that the BWO spectrum is completely matched with the standard diffraction card PDF#73-2020, and there was no impurity peak, which indicates that the BWO prepared by the experiment is the pure orthorhombic crystal structure with the unit cell parameter a = 0.5457 nm, b = 0.5436 nm and c = 1.6427 nm. In addition, all the diffraction peaks of AMO are in good agreement with the standard diffraction card PDF#08-0473 [20,28], and no other irrelevant diffraction peaks are found. This implies the synthesis of pure cubic AMO with the unit cell parameter a = b = c = 0.9313 nm.…”

“…The low light absorption range and poor photocatalytic performance lead to its rare application in the eld of photocatalysis [18]. Like most silver-based photocatalytic materials, the surface silver ions of the AMO material will be reduced to metallic silver due to light corrosion under the sunlight [19,20].…”

“…It is noted that when electronhole pairs recombine, a certain uorescence intensity will be produced. The stronger the uorescence intensity of the sample is, the higher the recombination e ciency of electron-hole pairs [20]. In short, the stronger uorescence intensity implies lower photocatalytic performance of the sample [41,42].…”

Triple-Channel Charge Transfer over W18O49/Au/g-C3N4 Z-Scheme Photocatalysts for Achieving Broad-Spectrum Solar Hydrogen Production

“…On the other hand, solid-state electron mediators not only promote Z -scheme charge transfer but also avoid undesired backward reactions; hence, they are considered as the ideal choice of mediators. Various types of solid-state electron mediators have been tested previously, including Au, Ag, Cu, and reduced graphene oxide (RGO) . Among these, Au is particularly efficient at facilitating charge-transfer dynamics, with additional merits associated with the localized surface plasmon resonance (LSPR) effects …”

Fabrication of a Novel AgBr/Ag2MoO4@InVO4 Composite with Excellent Visible Light Photocatalytic Property for Antibacterial Use

“…Many researchers combined them with other substances to learn their strengths and make up for their shortcomings, and then they prepared photocatalysts with better performance for various studies. Chen et al [23] fabricated a new β-Ag 2 MoO 4 /BiVO 4 heterojunction photocatalyst by a simple precipitation method at room temperature. The degradation rates for rhodamine B (RhB) of pure β-Ag 2 MoO 4 and BiVO 4 were not good, but the as-created β-Ag 2 MoO 4 /BiVO 4 photocatalyst had about 92.6% RhB degradation rate.…”
