“…[ 33 ] Simultaneously, the conjugate structure of rhodamine was broken down into small molecules upon continuous visible‐light irradiation. [ 34 ] The stability of the CNTs‐PAA/CNMS‐20 heterojunction membrane was further assessed by monitoring the cyclic photocatalytic degradation for RhB. As presented in Figure 5d, the CNTs‐PAA/CNMS‐20 composite membrane maintained its outstanding photocatalytic degradation performance (> 90%) after ten cycle's experiments, suggesting that the CNTs‐PAA/CNMS‐20 composite membrane can keep an efficient photocatalytic activity in long‐term use.…”

treatment technology an extremely tough task. [1] Currently, membrane separation technology has become the main channel to remediate the water environment attribu ting to its advantages, such as environ mental sustainability and energy saving. [2] Particularly, graphene oxide (GO) and carbon nanotubes (CNTs), have attracted comprehensive attention on constructing multifunctional separation membranes in the scientific field. [3] For one thing, they possess high surface areas that are ben eficial to achieve effective adsorption with watersoluble pollutants (dye molecules, bacteria, et al.). [4] For another, they can be taken as secondary reaction platforms for designing functional membranes through chemical crosslinking, interface assembly, and nanoparticle modification, which will enhance their capture ability for target compounds. [5] To date, the research on carbonbased membranes with versatility has brought inspiring achievements. For example, Liu and coworkers have designed a SiO 2 /GO composite mem brane through the modification of SiO 2 nanoparticle and eth ylenediamine. [6] It can purify the oilinwater (O/W) emulsion with the flux of 470 L m −2 h −1 and high retention capacity for dye molecules. Chen et al. have constructed a series of super hydrophilic CNTsbased composite membranes via hydrophilic Membrane separation is recognized as one of the most effective strategies to treat the complicated wastewater system for economic development. However, serious membrane fouling has restricted its further application. Inspired by sphagnum, a 0D/2D heterojunction composite membrane is engineered by depositing graphitic carbon nitride nano/microspheres (CNMS) with plentiful wrinkles onto the polyacrylic acid functionalized carbon nanotubes (CNTs-PAA) membrane through hydrogen bond force. Through coupling unique structure and chemistry properties, the CNTs-PAA/CNMS heterojunction membrane presents superhydrophilicity and underwater superoleophobicity. Furthermore, thanks to the J-type aggregates during the solvothermal process, it is provided with a smaller bandgap (1.77 eV) than the traditional graphitic carbon nitride (g-C 3 N 4) sheets-based membranes (2.4-2.8 eV). This feature endows the CNTs-PAA/CNMS membrane with superior visible-lightdriven self-cleaning ability, which can maintain its excellent emulsion separation (with a maximum flux of 5557 ± 331 L m −2 h −1 bar −1 and an efficiency of 98.5 ± 0.6%), photocatalytic degradation (with an efficiency of 99.7 ± 0.2%), and antibacterial (with an efficiency of ≈100%) ability even after cyclic experimental processes. The excellent self-cleaning performance of this all-in-one membrane represents its potential value for water purification.

“…Rhodamine B (C 28 H 31 ClN 2 O 3 ) is a xanthene dye, which is used as a water tracer fluorescent for the direction of flow and transport (Wang et al 2020b). This dye stands an extensive value in the textile industries due to the low production cost, high stability, and non-biodegradability (Worathitanon et al 2019). It is still controversial whether Rhodamine B is a carcinogenic and neurotoxic agent to human health (Al-Buriahi et al 2022).…”

Water contamination is an environmental burden for the next generations, calling for advanced methods such as adsorption to remove pollutants. For instance, unwanted biowaste and invasive plants can be converted into biosorbents for environmental remediation. This would partly solve the negative effects of invasive plants, estimated at 120 billion dollars in the USA.Here we review the distribution, impact, and use of invasive plants for water treatment, with emphasis on the preparation of biosorbents and removal of pollutants such as cadmium, lead, copper, zinc, nickel, mercury, chromate, synthetic dyes, and fossil fuels. Those biosorbents can remove 90-99% heavy metals from aqueous solutions. High adsorption capacities of 476.190 mg/g for synthetic dyes and 211 g/g for diesel oils have been observed. We also discuss the regeneration of these biosorbents.

“…Various organic pollutants enter the water through different sources, for example, textile, leather, cosmetics, and printing industry [1, 2]. The textile industry is the main factor leading to serious water pollution worldwide, and these dyes possess a serious threat to the water quality of the natural water bodies and aquatic organisms owing to their recalcitrant and persistent nature [3–5]. Furthermore, these dyes are also harmful to human beings when it sneaks into the human body and irritates the eyes, respiratory tract, and skin [6].…”
