Indoor air pollution presents a significant challenge to human health, driving the development of advanced materials for indoor environmental remediation. Metal–organic frameworks (MOFs) derived materials possess great promise as promising candidates for addressing this challenge. In this work, the delignified bamboo with multi-scale structure was employed as a substrate to fabricate ZIF-8@bamboo by in-situ and ex-situ growth strategies. The results demonstrated that the delignified bamboo exposed polysaccharided cellulose active group originally present in the bamboo cell walls. The pretreated bamboo was facilitated to the uniform growth of ZIF-8 crystals, and the loaded ZIF-8 exhibited high crystallinity and well-distributed morphological characteristics. Moreover, the successful growth of ZIF-8 increased the bamboo’s specific surface area. Additionally, the formaldehyde adsorption tests revealed that the ZIF-8@bamboo exhibited a 227.73 % improvement for formaldehyde adsorption rate at room temperature. Meanwhile, it also showed a rapid adsorption rate, high adsorption capacity, and reusable performance for formaldehyde. Furthermore, the as-prepared ZIF-8@bamboo demonstrated high removal efficacy for other indoor pollutants, including PM2.5 and PM10. Moreover, the ZIF-8@bamboo exhibited high indoor pollutant removal efficiency after five repeated cycles. Therefore, the ZIF-8@bamboo proposed in this work provides an effective solution to address indoor environmental pollution.

Fluorescent brighteners (FBs) are extensively used as important chemical additives in multiple industrial fields worldwide. The history of the use of global FBs spans over 60 years, but knowledge on their environmental occurrence and risks remains largely unknown. Here, we screened indoor dust and hand wipes from South China for a broad suite of 17 emerging FBs using a new comprehensive analytical method. All 17 FBs were detected in the indoor environment for the first time, most of them having been rarely investigated or never reported in prior environmental studies. Ionic FBs were found to be more abundant than nonionic ones. The median total concentrations of the 17 detectable FBs reached 11,000 ng/g in indoor dust and 2640 ng/m2 in hand wipes, comparable to or higher than those of well-known indoor pollutants. Human exposure assessment indicated that hand-to-mouth contact is a significant pathway for exposure to FBs, with a comparable contribution to that of dust ingestion. Most of the newly identified FBs are predicted to have persistent, bioaccumulative, or toxic properties. Our work demonstrates that FBs are another class of highly abundant, hazardous, and ubiquitous indoor pollutants that have been overlooked for decades and points to an emerging concern.

Nowadays, various harmful indoor pollutants especially including bacteria and residual formaldehyde (HCHO) seriously threaten human health and reduce the quality of public life. Herein, a universal substrate-independence finishing approach for efficiently solving these hybrid indoor threats is demonstrated, in which amine-quinone network (AQN) was employed as reduction agent to guide in-situ growth of Ag@MnO 2 particles, and also acted as an adhesion interlayer to firmly anchor nanoparticles onto diverse textiles, especially for cotton fabrics. In contrast with traditional hydrothermal or calcine methods, the highly reactive AQN ensures the efficient generation of functional nanoparticles under mild conditions without any additional catalysts. During the AQN-guided reduction, the doping of Ag atoms onto cellulose fiber surface optimized the crystallinity and oxygen vacancy of MnO 2 , providing cotton efficient antibacterial efficiency over 90 % after 30 min of contact, companying with encouraging UV-shielding and indoor HCHO purification properties. Besides, even after 30 cycles of standard washing, the Ag@MnO 2 -decorated textiles can effectively degrade HCHO while well-maintaining their inherent properties. In summary, the presented AQN-mediated strategy of efficiently guiding the deposition of functional particles on fibers has broad application prospects in the green and sustainable functionalization of textiles.

Water competitive adsorption and limited reaction sites on the micro-scale sensing area of micro-electro-mechanical system (MEMS) sensors are two bottleneck problems that restrict the detection of trace indoor polluted gases, leading to drifting and weak signals. To address this, a “duet-insurance” sensing strategy is proposed to protect and amplify the sensing signal. For the first-level protection, the well-designed double-layer structure consisting of Janus TpMa covalent organic framework (COF)/Eu-doped α-Fe 2 O 3 can resist diffusion of water molecules and facilitate the electron transfer from formaldehyde (CH 2 O) to sensing layers, benefiting from the outer hydrophobic character of Janus TpMa and the strong CH 2 O adsorption capacity of Eu-doped Fe 2 O 3 . For the second-level amplification, the unique variable temperature excitation facilitates the deep penetration of CH 2 O into the active sites across COF layers, enabling signal amplification through thermally actuated carrier modulation. The sensor demonstrates high sensing ability to the CH 2 O, with an ultra-low limit of detection of 794 ppt. Leveraging the novel sensing strategy, a multi-functional, visual sensing system is designed to identify multi-indoor pollution gases by feature signal encoding and color mapping, showcasing the promising potential for MEMS sensors based on Janus TpMa COF/Eu-doped α-Fe 2 O 3 materials.

Fe-MOF derivative (M-300) is successfully prepared by thermal treatment using MIL-100(Fe) as a precursor. The resulting M-300 catalyst displays excellent performance in the degradation of volatile organic compounds (VOCs) and the bacteriostasis to Escherichia coli under the visible light. In addition, the catalyst also exhibits the capacity of acetaldehyde degradation under actual sunlight. The high activity is attributed to the abundant exposure of the unsaturated Fe 2+ active site, which can significantly promote the transfer of photogenerated electron and the oxygen reduction process, thus improving the efficiency of the entire photocatalytic oxidation reaction. This work shows the application prospect of MOFs derivatives in the field of indoor photocatalytic purification, and also provides a new insight into the study of catalyst modification in photocatalytic degradation of pollutants.

Indoor pollution is a major health issue. In particular, urea pollution is drawing significant attention. Herein, we designed functional wooden window with the unique ability to photocatalytically degrade indoor pollutants, specifically urea. The transparent wooden window has been prepared via one-pot hydrothermal polymerization on a chemical-treated wood in order to incorporate resorcinol–formaldehyde. A hybrid wood denoted as resorcinol–formaldehyde-wood composite capable of photocatalytically degrading urea has been obtained. Mechanism study shows that the urea is degraded on composite interface via the as-formed hydroxyl radicals (·OH) generated from hydrogen peroxide. Further employing a large-scale (150 mm × 200 mm) resorcinol–formaldehyde-wood window for control of toilet urea pollution, a 100% urea removal efficiency was achieved in less than one hour.
