Room temperature synthesis and photocatalytic property of AgO/Ag2Mo2O7 heterojunction nanowires

Ag@Activated Carbon Felt Composite as Electrode for Supercapacitors and a Study of Three Different Aqueous Electrolytes

“…Those located at 368.1 and 374.1 eV correspond to metallic silver phase, 20 and those at 367.2 and 372.0 eV correspond to silver oxide phase. 28,29 This result demonstrates the coexistence of two different silver formations on the surface on the Ag@ACF. Taking into account that XPS resolution is limited to few nm deeper in the sample surface, these species exist on the surface of the analyzed material.…”

“…From the fit of O 1s emission line (Figure 3b), the peaks at 530.9 and 532.6 eV were assigned to AgO species 28 and C=O bond 30 respectively. Three peaks of the C 1s XPS spectrum are located at 284.7, 285.7 and 287.8 eV (Figure 3c), corresponding to the C-C, C-O and C=O bonds respectively.…”

Rodlike AgI/Ag2Mo2O7 Heterojunctions with Enhanced Visible-Light-Driven Photocatalytic Activity

“…Two distinct peaks at 232.1 and 235.3 eV (corresponding to Mo 6+ ) are seen in the Mo 3d high-resolution spectra (Figure 2c). As shown in Figure 2d, the high-resolution O 1s peak of S5 is deconvoluted into three peaks at binding energies of 530.2, 531.5, and 533.3 eV, corresponding to Mo–O–Mo bonds, 39 oxygen vacancy, 54 and adsorbed oxygen on the surface 55 of the sample, respectively. Notably, Ag 3d and I 3d peaks in S5 move to a positive position compared with those in AgI, whereas the peak of Mo 3d in S5 shifts slightly to lower binding energies compared with that in Ag 2 Mo 2 O 7 .…”

“…29,30 Ag 2 Mo 2 O 7 materials with various morphologies (such as nanowires, 30−33 nanoparticles, 34 flower-like, 35 broom-like microstructures, 35 and microrods 36−38 ) have been reported. Nevertheless, there are only a few studies on Ag 2 Mo 2 O 7 -based heterojunctions such as AgO/Ag 2 Mo 2 O 7 , 39 g-C 3 N 4 /m-Ag 2 Mo 2 O 7 , 40 Ag 2 Mo 2 O 7 @AgBr–Ag, 41 and Ag 3 PO 4 /Ag/Ag 2 Mo 2 O 7 . 42…”

Graphene-wrapped Ag 3 PO 4 /LaCO 3 OH heterostructures for water purification under visible light

“…One of the key objectives in this field is to develop high efficiency photocatalyst materials that can efficiently utilize sunlight as the energy source [5]. Thus far, various visible light active photocatalysts have been developed, such as NiS/CdS [6], ZnInS 4 [7], AgO/Ag 2 Mo 2 O 7 [8] , CdInS 4 [9], and TiO 2-x N x [10]. However, the efficiency of these photocatalysts is still too low for industrial application, and therefore materials with high efficiency and long-term stability are still being actively sought [11].…”
