“…These advantages afford the S-scheme heterojunction a significant edge in pollutant elimination. [33][34][35][36][37][38][39] Herein, a novel Ag 6 Si 2 O 7 /CaSnO 3 heterojunction is devised and synthesized via a hydrothermal process using the S-scheme to overcome energy harvesting issues and poor conductivity of CaSnO Thus, we can summarize this paper such that in the first part, the Ag 6 Si 2 O 7 /CaSnO 3 nanocomposites and their counterparts are characterized in the full spectrum to ensure the successful synthesis, and in the last part, the performance of the nanocomposites is evaluated against RhB. The results in this section show that the photocatalytic performance has been improved significantly.…”

“…As shown in Figure 13d, the P-S-T/C still showed high photocatalytic performance under simulated sunlight irradiation after five cycles, which was higher than that of the photocatalysts reported so far. 75,76 All of these indicated that P-S-T/C had excellent cyclic stability.…”

Multicomponent Composite Membrane with Three-Phase Interface Heterostructure as Photocatalyst for Organic Dye Removal

et al. 2022

A multicomponent composite membrane (P-S-T/C) with three-phase interface heterostructure is ingeniously designed. A polydopamine (PDA)-modified conductive carbon fiber cloth (C FC ) is used as the substrate. Activated poly(vinylidene fluoride) (PVDF) with titanium dioxide (TiO 2 ) and a silicon dioxide (SiO 2 ) aerogel are electrospun as the top layer. The three-phase interface heterostructure was formed by TiO 2 , conductive C FC , and the SiO 2 aerogel. Its photocatalytic performance is validated by photodegradation of organic dyes in a low-oxygen (O 2 ) water environment. On combining with the capillary condensation of a bilayer structure, P-S-T/C exhibits excellent removal capability for anionic and cationic dyes. Moreover, P-S-T/C exhibits excellent stability and recyclability under simulated sunlight. The mechanism study indicates that the separated photogenerated carriers diffuse to the composite membrane surface rapidly on the three-phase interface of P-S-T/C. The abundant O 2 adsorbed on the porous SiO 2 aerogel surface acts as an electron (e – )-trapping agent, which can also decrease the work function of the composite materials. Superoxide radicals ( • O 2 – ) play a dominant role in the reaction of photodegradation supported by a free radical-trapping experiment. This work paves a way to design a membrane with photocatalytic performance by constructing the interface heterostructure.
