“…Therefore, the above analyses verify that the Ag 3 PO 4 -WO 3 /MWCNTs composite have been successfully prepared. In additional, a lattice fringe with a spacing of 0.231 nm, corresponding to the (1 1 1) crystalline plane of metallic Ag [27], is also showed in Fig. 2b.…”

“…Therefore, the photo-generated electrons in the Ag 3 PO 4 could be easily transferred to the CB of WO 3 , while the photo-generated holes in the WO 3 could migrate to the VB of Ag 3 PO 4 . Thus the orange II adsorbed on Ag 3 PO 4 -WO 3 /MWCNTs could be directly oxidized by the holes on Ag 3 PO 4 surface [27]. At the same time, due to the good conductivity of MWCNTs, the electrons in the CB of WO 3 and Ag 3 PO 4 could also be easily transferred to the surface of MWCNTs to participate in the photocatalytic reaction.…”

“…Especially, the redox potentials (CB and VB) of WO 3 are more positive than those of Ag 3 PO 4 [26]. The transfer processes of photo-generated electrons and holes between Ag 3 PO 4 and WO 3 have been described by Yu [26] and Liu et al [27]. It implies that under light irradiation the photo-generated electrons could move from the CB of Ag 3 PO 4 to that of WO 3 , and the photo-generated holes in the VB of WO 3 could migrate to that of Ag 3 PO 4 , which avoid the recombination of the electron-hole pairs and accumulation of photo-generated electrons on CB of Ag 3 PO 4 , and thus increase the stability of Ag 3 PO 4 .…”

New ternary composites based on three dimensionally ordered macroporous (3DOM) SrTiO3 (CdS/Au/3DOM-SrTiO3) were prepared and used as photocatalysts in visible light (λ > 420 nm) photocatalytic water splitting for hydrogen evolution.Through optimizing the pore size of 3DOM-SrTiO3 materials and the loading amounts of Au and CdS, CdS/Au/3DOM-SrTiO3(300), templated by 300 nm sized poly(methyl methacrylate) colloids, was found to exhibit a remarkably enhanced photocatalytic hydrogen evolution rate (2.74 mmol/h•g), which was 3.2 times as high as that of CdS/Au/C-SrTiO3 catalyst based on commercial SrTiO3. This notably enhanced photocatalytic performance was mainly attributed to the slow photon enhancement effect of 3DOM-SrTiO3(300) material, which significantly promoted the light harvesting efficiency of ternary composite for the slow photon region of 3DOM-SrTiO3(300) was well matched with the optical absorption band of photocatalyst. Further depositing Pt nanoparticles on CdS/Au/3DOM-SrTiO3(300) composite as a co-catalyst, an extraordinarily high hydrogen evolution rate (up to 5.46 mmol/g•h) and apparent quantum efficiency (42.2% at 420 nm) were achieved because of the synergistic effect of efficient carrier separation, Au SPR effect, and slow photon effect. Furthermore, these ternary CdS/Au/3DOM-SrTiO3 composite photocatalysts were very stable and could be easily recycled four times in visible light photocatalytic water splitting experiments without any loss in activity.3 Keywords Three-dimensionally ordered macroporous material; CdS/Au/3DOM-SrTiO3; Ternary composite; Hydrogen production from water splitting; Slow photon effect.4

The availability of robust, versatile and efficient photocatalysts has been a main bottleneck in practical applications of photocatalytic degradation of organic pollutants. Herein, N-WO 3 /Ce 2 S 3 nanotube bundles (NBs) were synthesized and successfully immobilized on a carbon textile, resulting in a flexible and conducting photocatalyst. Due to the large interfacial area between N-WO 3 and Ce 2 S 3 , the interwoven 3D carbon architecture and, more importantly, the establishment of a heterojunction between N-WO 3 and Ce 2 S 3 , the resultant photocatalyst exhibits excellent light absorption capacity and superior ability to separate photoinduced electron-hole pairs for the photocatalytic degradation of organic compounds in air and water media. Theoretical calculations confirm that the strong electronic interaction between N-WO 3 and Ce 2 S 3 could be beneficial to the enhancement of the charge carrier transfer dynamics of the as-prepared photocatalyst. This work provides a new protocol for constructing efficient flexible photocatalysts for application in environmental remediation.
