“…The current methods of controlling oil spills include using booms (Hubbe et al, 2013), skimming (Kinner et al, 2014), and burning the oil on the surface of the water (Prendergast and Gschwend, 2014). These techniques are time consuming and energy inefficient, and they create pollution and require excessive energy for recovery of the oil.…”

“…Regarding sorbents, these materials are typically most effective in oil capture if they are hydrophobic and have high surface area, low specific gravity and high buoyancy in water . Mechanical recovery of the oil and sorbent reuse are also desirable features, and low cost is critical for uptake in the field . Impressive advances have been made for both sorbents and membranes, with highly effective materials reported for oil separation and recovery from water .…”

Crude oil and hydrocarbon fuel spills are a perennial threat to aquatic environments. Inexpensive and sustainable sorbents are needed to mitigate the ecological harm of this pollution. To address this need, this study features a low‐density polysulfide polymer that is prepared by the direct reaction of sulfur and used cooking oils. Because both sulfur and cooking oils are hydrophobic, the polymer has an affinity for hydrocarbons such as crude oil and diesel fuel and can rapidly remove them from seawater. Through simple mechanical compression, the oil can be recovered and the polymer can be reused in oil spill remediation. The polysulfide is unique because it is prepared entirely from repurposed waste: sulfur is a by‐product of the petroleum industry and used cooking oil can be used as a comonomer. In this way, sulfur waste from the oil industry is used to make an effective sorbent for combatting pollution from that same sector.

“…Slow and inefficient responses to oil spills have catastrophic and far‐reaching implications for the livelihood of local populations and the environment . Various technologies and devices have been proposed for oil remediation, such as, in situ burning at the spill site, dissipation with dispersants, and recovery with mechanical skimmers or vacuums . However, in some cases, these methods can have additional negative environmental impacts or demonstrate a low oil–water separation efficiency.…”

Efficient cleanup of viscous crude oil spill is a worldwide challenge due to its sluggish flowability at room temperature. Conventional oil remediation methods using physical absorbers, skimmers, and vacuum technologies either demonstrate low absorption efficiency or have severe operational restrictions. Inspired by the highly efficient and passive transpiration process in trees, a solar-heated carbon absorber (HC-Wood) with an inherited wood structure of aligned channels for rapid crude oil absorption is reported. The unique porous structure of the carbon absorber can extend the light absorption paths, guide the direction of heat transport, and decrease the resistance to oil flows, endowing the carbon absorber a large efficiency of solar absorption (>99% of the incident irradiation), excellent thermal management, and fast capillarity-driven oil absorption behavior. The low tortuosity of the porous structure together with the efficient solar-thermal conversion enable the absorber to demonstrate a crude oil absorption rate of 1550 mL m −2 in 30 s under 1 sun irradiation, which is 10 times faster than previously reported results for passive absorption of viscous crude oil. Given the unique structural design, low operating cost, and rapid oil absorption speed, this work provides a promising solution for addressing catastrophic large-area viscous oil spills.
