Summary: This review suggests that phytoremediation can be used for the decontamination of micro- and nano-plastics. Microplastics and nanoplastics are emerging contaminants that have raised concerns due to their pollution and potential eco-toxicity. However, there is limited review on the decontamination of these pollutants. Recent studies have confirmed the uptake of micro- and nano-plastics by plants. This review presents the pollution of micro- and nano-plastics and highlights the interaction between these pollutants and plants. It proposes that phytoremediation could be a potential method for in situ remediation of environments contaminated with micro- and nano-plastics, and discusses the mechanisms, influencing factors, existing problems, and future research needs. This review provides new insights into the development of plant-based processes for decontamination of emerging pollutants and mitigation of toxicity to ecosystems caused by micro- and nano-plastics.

Summary: In this study, a new strategy for simultaneous phosphorus and fluoride wastewater treatment was proposed using capacitive deionization technology (CDI) with modified activated carbon fiber felt (ACF) electrodes. The modified A@Fe-ACF electrode, obtained through a two-step impregnation method, showed increased oxygen-containing functional groups on ACF, providing more adsorption sites. Introducing Fe synergistically promoted the adsorption of phosphorus and fluorine by increasing electron transfer efficiency on the A@Fe-ACF. Under optimal conditions (voltage intensity 1.5 V, pH 7, plate spacing 1 cm), removal efficiencies of total phosphorus (TP) and total fluorine (TF) reached 89.4% and 85%, respectively, with a dominant chemical adsorption mechanism. Additionally, the A@Fe-ACF electrode exhibited good recyclability and stability after five cycles.

Summary: Graphitic carbon nitride (g-C3N4), as a metal-free polymer, has attracted extensive attention compared to its inorganic counterparts due to its unique physical and chemical properties. However, its low specific surface area, high charge recombination rate, and insufficient light absorption limit its application in photocatalysis. Sulfur doping has been proven to be an efficient strategy to promote light absorption and carrier separation, leading to the synthesis of modified composites with impressive results in photocatalysis.

Summary: In this study, sulfur-doped g-C3N4 (SCN) nanotubes were modified with nitrogen-doped carbon quantum dots (N-CQDs) derived from pig manure to synthesize SCN/N-CQDs composite photocatalyst. The modified photocatalyst showed improved electron-hole pairs separation rate and enhanced photocatalytic degradation efficiency of tetracycline (TC) in antibiotic wastewater. The photocatalyst demonstrated the generation of hole, hydroxyl radicals, and superoxide radicals, which played a crucial role in the efficient degradation of TC. The biotoxicity analysis confirmed that the photodegradation of SCN/N-CQDs did not produce biotoxicity to Escherichia coli (E. coli).

Summary: Emerging photoelectrocatalytic (PEC) systems, integrating the advantages of photocatalysis and electrocatalysis, have great potential in addressing global organic pollution in water environments. Graphitic carbon nitride (CN) is a promising material for organic pollutant degradation due to its environmental compatibility, stability, low cost, and visible light response. However, there are challenges such as low specific surface area, low electrical conductivity, and high charge complexation rate, which affect the degradation efficiency of PEC reaction and the mineralization rate of organic matter. This review focuses on the progress of functionalized CN in recent years and critically evaluates their degradation efficiency for PEC reaction.
