MXene-based materials for oil-water separation: mechanisms, performance, environmental implications, and future directions.
Review in RSC advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Oil-water contamination from industrial effluents and accidental spills presents a persistent environmental challenge, necessitating efficient and sustainable separation technologies. Two-dimensional MXenes, a class of transition-metal carbides and nitrides, have emerged as highly promising materials for oil-water separation due to their atomically thin layered structures, high electrical conductivity, and abundant surface terminations (-O, -OH, and -F). These intrinsic characteristics impart superhydrophilicity and underwater superoleophobicity, enabling selective water permeation while effectively repelling oil phases. To further enhance separation performance, a wide range of MXene-based architectures have been developed, including polymer-MXene composite membranes, three-dimensional porous hybrids with carbon nanomaterials, and multifunctional composites incorporating metal oxides, biopolymers, or clays to improve mechanical robustness, fouling resistance, and chemical stability. Oil-water separation using MXenes proceeds through synergistic mechanisms such as interlayer nanochannel size-sieving, wettability-controlled selective transport, capillary-driven sorption in aerogels and sponges, photothermal-assisted demulsification of viscous oils, and externally stimulated (magnetic or electro-assisted) oil recovery. This review emphasizes recent advances in MXene-based material design, separation mechanisms, and composite engineering for oil-water remediation, with particular focus on establishing a mechanistic framework that links material properties to separation behavior across different system configurations. By identifying current limitations and future research directions, this review aims to provide a comprehensive framework for the rational development and practical deployment of MXene-enabled oil-water separation technologies.
