“…The textile sector has long been associated with the most serious pollution source , because of the effluent from printing and dyeing . Worse still, dye molecules have a stable aromatic structure that can stay in the water for a long time, resulting in toxicity on aquatic and agricultural lands and severely damaging the ecosystem. , As a result, the degradation of organic dyes in wastewater has emerged as a critical issue in the treatment of water pollution. , …”

Emerging technologies such as a triboelectric nanogenerator (TENG) can always draw beneficial inspiration from traditional industrial design and thus become more efficient in constructing self-powered electrochemical systems. Inspired by the Stirling engine, a cyclic reciprocating parallel triboelectric nanogenerator (CRP-TENG) is proposed by combining stacked triboelectric units for harvesting wind energy and driving the electro-Fenton degradation of dye wastewater. Different from the classical rotational TENG, the CRP-TENG can convert rotating motion into horizontally straight reciprocating motion and present higher output performance than that of the cyclic reciprocating series TENG under the same operating conditions. The CRP-TENG shows a very stable output over ∼9000 cycles in the electrochemical process, where corn straw biochar was used as an efficient electrolytic cathode material for the oxidation of methyl orange. This work not only proposes a high-performance design of the TENG but also extends more common bioderived carbon materials in the development of environmentally friendly electrochemical systems.

“…Therefore, it is of great significance to explore an effective method to remove pollutants in water. Numerous technologies have been used to eliminate organic pollutants from aqueous solutions, such as adsorption, microbial degradation, electrochemical processes, advanced oxidation, and photocatalytic degradation. , Among these technologies, adsorption is considered one of the most effective methods for removing organic dyes from wastewater because it is efficient, low-cost, and does not produce any byproducts . Various adsorbents, such as zeolite, biochar, clay, metal–organic framework, and carbon nanotubes, have been extensively studied in the treatment of organic pollutants in aqueous solutions.…”

Effective adsorption and separation of organic pollutants from wastewater are essential to protecting the environment and human health. In this study, porous organic polymers (PAPOPs) containing a tri(polyhydroxy-phenyl-azophenyl) benzene skeleton structure were synthesized through diazotization coupling without any catalyst participation. It was found that PAPOPs have a high specific surface area, a mesoporous structure, a good thermal stability, and electronegativity. Based on these characteristics, PAPOPs demonstrated a maximum adsorption capacity of 1773.15 mg g −1 for rhodamine B (RhB), 1091.75 mg g −1 for Congo red, and 306.33 mg g −1 for tetracycline hydrochloride. Furthermore, PAPOPs also exhibited good selectivity and an extremely fast adsorption rate for RhB. The adsorption efficiency of PAPOPs did not significantly decrease even after seven repeated uses, indicating their broad application prospects in wastewater treatment.

“…Cotton fibers, a natural resource, offer various advantages, such as easy availability, cost-effectiveness, lightweight nature, softness, absorbency, and breathability . However, the traditional process of dyeing cotton fabrics using reactive dyes requires substantial inorganic salt to enhance the interaction between the negatively charged cotton and the anionic dyes . Despite this, only 60–65% dye utilization is attainable, resulting in substantial wastewater generation containing inorganic salts and dyes, posing environmental hazards and raising production expenses. , Consequently, finding an effective solution to this predicament is crucial.…”

Cotton fibers have received considerable attention owing to their functional properties. Current research endeavors have shifted toward devising straightforward and versatile approaches for modifying cotton fibers. Herein, a simple and feasible method was proposed for preparing multifunctional cotton fibers. This method entailed subjecting cotton fibers to alkaline conditions, prompting the epoxy group in epoxidized soybean oil to engage in a ring-opening reaction with the hydroxyl group in cotton fibers and the amino group in polyhexamethylene guanidine hydrochloride. Epoxidized soybean oil acted as a bridge, forming a covalent bond between polyhexamethylene guanidine hydrochloride and cotton fibers, thereby facilitating the cationization of cotton fibers. Structural changes in the modified cotton fibers were characterized using Fourier transform infrared spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and energy-dispersive X-ray spectroscopy. The modified cotton fibers were also evaluated for their dyeing, antibacterial, and hydrophobic properties. The results demonstrated that the dye exhaustion and total dye utilization of modified cotton in salt-free dyeing were much higher than those of raw cotton in conventional dyeing. The water contact angle of the modified cotton fiber reached 139.5°, and their antibacterial properties were partially improved. Importantly, this chemical modification was performed under mild conditions, highlighting its simplicity and environmentally friendly nature.
