“…Zhai et al, 53 loaded metal-organic framework (MOF) (UiO-66-NH2) onto a polyacrylonitrile nanofibermembrane and prepared UiO-66-NH 2 /PAN-based capacitive gas sensor with excellent sensing performance for SO 2 gas in the range 1-125 ppm. The authors further improved the detection ability of the sensor toward trace SO 2 by modifying the structure with 2,3,4-trihydroxybenzaldehyde (THBA), revealing that the abundant hydroxyl groups present on THBA improved the SO 2 adsorption performance of the material, enabling a low detection limit (0.1 ppm).…”

Increased environmental pollution is becoming one of the greatest problem the world is facing nowadays causing irreparable damage to the earth. Because of their novel and tunable physicochemical properties, nano materials have attracted great attention among researchers as promising materials to combat environmental challenges. Developing nanotechnology have triggered a great deal of interest in these structures for pollution monitoring and treatment, enabling new technologies for identifying and addressing environmental problems. Even though achieving environmental pollution control is a challenging task using conventional materials, revolutionary progress has been observed with the advancements in nanotechnology, showing that precisely modified nano materials can be used for purposes such as treatment of polluted atmosphere, industrial and domestic wastewater, natural water, and soil. In this paper we review and discuss the environmental applications of nano materials as nano sensors employed for combating atmospheric and aquatic pollution. Keywords: enviro

Recovering cobalt from waste batteries is crucial for resource recycling and environmental protection. Here, MOF-OH, a Zr-based MOF, was synthesized and merged into a polyacrylonitrile (PAN) matrix to create MOF-OH-PAN nanofibers (NFs). These NFs showed a high cobalt ion adsorption capacity of 33.1 mg/g, retaining over 90% of the capacity after six cycles. The adsorption mechanism involves Co(II) surface diffusion followed by strong bonding with functional groups. This technology enables efficient cobalt recovery from waste batteries, supporting reuse and reducing resource depletion and environmental pollution. The study provides insights into waste battery resource management, highlighting environmental and economic benefits and contributing to green resource recovery and circular economy initiatives.

“…1 Due to abundant activated sites in frameworks, various chemical groups are capable of being introduced into the frameworks by PSM. [12][13][14] Additionally, introducing chemical groups in MOFs by PSM can maintain or increase the structural stability of the frameworks, 15,16 and thus is promising in practical applications.…”
