Black lead molybdate nanoparticles: Facile synthesis and photocatalytic properties responding to visible light

“…Typical PbMoO 4 nanoparticles synthesized in different medium have different light absorption in the visible range (400 ~ 800nm). The products synthesized in aqueous medium are white and show poorer absorption of visible light which is the same as most of the PbMoO 4 nanomaterials in the previous works [32][33][34][35][36][37]. But the as-obtained products in glycol medium show better absorption of visible light which is consistent with the black appearance.…”

“…They will react with the adsorbed oxygen in the solution for producing oxygen radicals and hydroxyl radical which has a strong degradation effect on organic dye molecules. Additionally, larger specific surface area will not only supply more active sites for the degradation reaction of organic compounds, but also effectively promote the separation efficiency of the electron-hole pairs [37,39] A c c e p t e d M a n u s c r i p t 16 and larger specific surface area.…”

“…: Pb-Bi-Mo-O system [27], Ag-PbMoO 4 composite [37], fullerene-modified PbMoO 4 [38], and carbon microspheres@PbMoO 4 core-shell structures [39], etc. It follows that PbMoO 4 nanomaterials are a kind of potential photocatalysts and very worthy of further investigating.…”

Visible-light driven photocatalytic degradation of rhodamine B by Ag/Bi2WO6 heterostructures

“…Under visible-light irradiation, photo-induced electron-hole pairs are generated in Bi 2 WO 6 due to surface plasmon resonance [12]. Due to the high Schottky barrier at the metalsemiconductor interface, the photo-induced electrons diffuse to Ag nanoparticles and combine with adsorbed oxygen to form superoxide radicals (O 2 À ) [11,13]. Concurrently, photogenerated holes on VB of Bi 2 WO 6 react with OH -or H 2 O to form OH radicals [14].…”

Synthesis, structure, and thermal stability of new scheelite-type Pb1−3x□xPr2x(MoO4)1−3x(WO4)3x ceramic materials

“…They have been used as laser host materials, Raman lasers, optical fibers, humidity sensors, magnetic and photoluminescence materials, and catalysts [1][2][3][4][5][6][7][8][9][10][11][12][13]. Among them, lead molybdate and lead tungstate are very attractive materials because of their applications as acousto-optical modulators, deflectors, ion conductors, and solid-state scintillators for a nuclear instrumental application [14][15][16][17][18][19][20][21][22].…”
