“…9[l] and the rate constant calculated was 0.785 × 10 −2 L mol −1 min −1 . cSiO 2 @DFNS/Ag nanocomposites efficiently degraded 2-NA with a rate constant of 9.62 × 10 −3 s −1 in 160 min, 126 Ag–P(NIPAM- co -MAA) hybrid microgels degraded 2-NA with a rate constant of 0.181 to 0.350 min −1 , 127 the PVDF/microgel@Pd membrane degraded 2-NA up to 96.2% with first-order kinetics (rate constant = 0.035 min −1 ), 125 Ag/Ag 2 MoO 4 and Ag/Ag 2 WO 4 also degraded 2-NA with rapid conversion, 128 and Vitis labrusca Rachis extract mediated Cs-Ag/Fe 2 O 3 nanoparticles successfully degraded 2-NA. 129 Table S1 (ESI†) compares the photocatalytic activity of AGC NCs in the degradation of tested dyes.…”

Construction of a AgBr–Ag2MoO4 heterojunction and its photocatalytic sterilization activity

“…The two peaks at 367.78 eV (Ag 3d 3/2 ) and 373.78 eV (Ag 3d 5/2 ) are ascribed to Ag + in AgBr–Ag 2 MoO 4 . 25–27 The high-resolution Mo 3d spectra are shown Fig. 4(c).…”

Interface matters: Design of an efficient α-Ag2WO4/Ag3PO4 photocatalyst

“…The combination of metal and semiconductor significantly enhances the activity due to two main features: the formation of a Schottky barrier between the metal NPs, resulting in the increased separation efficiency of photogenerated (e -─h + ) pairs (Bai, Zong et al 2014). The high electron trapping ability of NPs help to effectively promote the conductivity of NPs, which can then be directly injected into the conduction band of semiconductors (Zheng, Huang et al 2011), thereby facilitating the charge separation at the interface between NPs and semiconductor, thus improving its photocatalytic ability (Zhou, Liu et al 2012, Faccin, San-Miguel et al 2017, Assis, Cordoncillo et al 2018, Li, Liu et al 2018, Sofi, Majid et al 2018, da Silva, Faccin et al 2019, Lemos and Vega 2019, Sofi and Majid 2019, Koyappayil, Berchmans et al 2020, Nubla and Sandhyarani 2020, Song, Xie et al 2020, Xia, Min et al 2021.…”

“…As consequence Ag NPs/Ag3PO4 and Ag NPs/α-Ag2WO4 composite can be formed, respectively. These composite present SPR effect associated to the ease formation Ag NPs on the surface of these semiconductors (Botelho, Sczancoski et al 2015, Liu, Huang et al 2017, Yan, Guan et al 2017 Majid 2019, Paulo de Campos da Costa, , Song, Xie et al 2020.…”
