“…Additionally, it is inherently hydrophobic because of its butyryl chains (Huang et al 2018). Recently, Tanvir et al (2020) produced superhydrophobic electrospun CAB fibers that exhibited four times higher oil adsorbent capacity (60 g/g) than commercial polypropylene. The authors also reported that the surface porosity of CAB fibers considerably increased the oil sorption capacity, with the hydrophobicity of the porous fibers being superior than that of non-porous CAB fibers.…”

Cellulosic materials have gained a lot of attention in the last decades because of their abundancy, renewability and excellent physicochemical properties. Meanwhile, research on nanofibers has also been increasing with the aim of producing or modifying materials that can have a wide range of applications, such as tissue engineering, drug delivery, protective clothing and wound dressing. In order to produce these fibers, electrospinning is shown to be a promising and extensively used technique. Electrospun cellulosic fibers maintain the optimal characteristics of cellulose while improving its surface area to volume ratio and mechanical properties, in addition to the possibility of surface tailoring of bulk materials. However, there are several limitations related to the utilization of cellulose and most of its derivatives with the electrospinning technique. Poor solubility in most common solvents and inability to melt are major drawbacks. Thus, this review describes mostly recent research in which cellulose and its derivatives have been the feedstock for fabrication of nanofibers by electrospinning, exploring processing details and potential applications.

The conservation of ocean and freshwater have been crucial issues over the past decades, and oil/water separation is a well‐known technology to restore polluted water systems. In the meantime, oil sorbents serve as a promising means of achieving water conservation to recover from oil spills, which require a multi‐factorial approach to review high selectivity, capacity, and rate of oil recovery. However, reusability is a critical component to consider in incidents with large‐scale spills. With the development of sorbent technology, some studies have progressed to explore surface engineering and material design for high oil sorption capacity and durability. Thus, this systemic review, a summary of sorbent developments, serves as a guide to understanding practical applications that can apply to large‐scale oil spills and recognize remaining issues. In this review, the oil weathering process and oil sorption mechanisms in relation to the characteristics of target pollutants are introduced. Then, this comprehensive review focuses on materials in advanced sorbents. These materials have properties including, aligned channels for fast sorption, self‐heating capabilities for viscous oil cleanup, and magnetic‐responsiveness to enhance a collection of final products. The perspective and challenges for the next generation of oil spills remediation technology‐based oil sorbents materials are finally presented in the last section.

“…The suspensions were vibrated at 180 rpm for 12 h at 298 K. After that, the composite was collected by ltrations. To determine the adsorbed Ce 4+ , the residue Ce 4+ concentration was measured by CPA-MA according to the previous report [1,2], and the adsorbed Ce 4+ can be calculated by the difference between the original and the residue concentrations. Naked eyes and a solid-state visible spectrophotometer were used to qualitatively and quantitatively investigate the color change of the hybrid after Ce 4+ loading.…”

Effective strategies to deal with rare earth pollution are urgently needed due to the overexploitation of rare earths resource. In this study, a novel nanocomposite of UiO-66-NH2/CPA-MA denoted as UA was successfully synthesized, which can simultaneously remove and detect Ce4+ in water. The hybrid consists of UiO-66-NH2 and CPA-MA. Based on the high adsorption performance of UiO-66-NH2, it can remove Ce4+ with high capacity by adsorption. Moreover, it can change its color from olive drab to light cyan depending on the adsorbed Ce4+ concentration, and the chroma is linearly related to the Ce4+ concentration. So UA can be used to qualitatively and quantitatively detect Ce4+ by its color changing. The kinetics of adsorption course were investigated in details. The anti-inference ability of the nanocomposite in co-existing systems were carefully evaluated. The results indicate that UiO-66-NH2/CPA-MA is highly potential to deal with Ce4+ pollutions due to its bi-functionality.
