“…When any of the factors of TA, light, catalyst or electricity are absent, the catalytic effect is greatly reduced. Due to the synergistic effect of CDI and photocatalysis with TA attached, this PCS process exhibits a robust Cr(VI) photoreduction capability, which is superior to most of the current POPs-based photocatalysts ( Table S5 [ 21 , 46 , 47 , 48 , 49 , 50 ]). For 10 ppm Cr(VI), 100% removal can be achieved in 60 min.…”

The removal of Cr(VI), a highly-toxic heavy metal, from industrial wastewater is a critical issue in water treatment research. Photocatalysis, a promising technology to solve the Cr(VI) pollution problem, requires urgent and continuous improvement to enhance its performance. To address this need, an electric field-assisted photocatalytic system (PCS) was proposed to meet the growing demand for industrial wastewater treatment. Firstly, we selected PAF-54, a nitrogen-rich porous organic polymer, as the PCS’s catalytic material. PAF-54 exhibits a large adsorption capacity (189 mg/g) for Cr(VI) oxyanions through hydrogen bonding and electrostatic interaction. It was then coated on carbon paper (CP) and used as the photocatalytic electrode. The synergy between capacitive deionization (CDI) and photocatalysis significantly promotes the photoreduction of Cr(VI). The photocatalytic performance was enhanced due to the electric field’s influence on the mass transfer process, which could strengthen the enrichment of Cr(VI) oxyanions and the repulsion of Cr(III) cations on the surface of PAF-54/CP electrode. In addition, the PCS system demonstrates excellent recyclability and stability, making it a promising candidate for chromium wastewater treatment.

“…The already mentioned TzDA framework, integrated within a Z-scheme heterojunction with BiOBr, 179 alternatively participated in a similar heterojunction with AgBr/Ag. 192 The theoretical weight fraction of the carbon component within the hybrid structure spanned between 5 and 15 wt%. BET analysis demonstrated that the surface area of the carbon component was appreciable diminished due to the growth of AgBr nanoparticles.…”

“…Recently, researchers have prepared several heterojunction photocatalysts with different metal NPs for organic pollutants degradation. In addition, various modification methods for the plasmonic-based heterojunction photocatalyst have been proposed by loading metal NPs as co-catalysts into the heterojunction photocatalysts [ 37 , 38 ]. Thus, many reviews have encouraged the use of simple heterojunction photocatalysts for organic pollutants degradation [ 39 – 41 ].…”

Organic pollutants in wastewater are the biggest problem facing the world today due to population growth, rapid increase in industrialization, urbanization, and technological advancement. There have been numerous attempts to use conventional wastewater treatment techniques to address the issue of worldwide water contamination. However, conventional wastewater treatment has a number of shortcomings, including high operating costs, low efficiency, difficult preparation, fast recombination of charge carriers, generation of secondary waste, and limited light absorption. Therefore, plasmonic-based heterojunction photocatalysts have attracted much attention as a promising method to reduce organic pollutant problems in water due to their excellent efficiency, low operating cost, ease of fabrication, and environmental friendliness. In addition, plasmonic-based heterojunction photocatalysts contain a local surface plasmon resonance that enhances the performance of photocatalysts by improving light absorption and separation of photoexcited charge carriers. This review summarizes the major plasmonic effects in photocatalysts, including hot electron, local field effect, and photothermal effect, and explains the plasmonic-based heterojunction photocatalysts with five junction systems for the degradation of pollutants. Recent work on the development of plasmonic-based heterojunction photocatalysts for the degradation of various organic pollutants in wastewater is also discussed. Lastly, the conclusions and challenges are briefly described and the direction of future development of heterojunction photocatalysts with plasmonic materials is explored. This review could serve as a guide for the understanding, investigation, and construction of plasmonic-based heterojunction photocatalysts for various organic pollutants degradation. Graphical abstract Herein, the plasmonic effects in photocatalysts, such as hot electrons, local field effect, and photothermal effect, as well as the plasmonic-based heterojunction photocatalysts with five junction systems for the degradation of pollutants are explained. Recent work on plasmonic-based heterojunction photocatalysts for the degradation of various organic pollutants in wastewater such as dyes, pesticides, phenols, and antibiotics is discussed. Challenges and future developments are also described.
