Superhydrophobic aerogel blanket with magnetic and solar heating effect enables efficient continuous cleanup of highly viscous crude oil

Recent advances in functional micro/nanomaterials for removal of crude oil via thermal effects

“…In addition to using solar heating, Joule heating, or alternating magnetic fields heating individually, the synergistic effect of multiple heating methods to assist crude oil recovery has a broader use scenario, providing a more promising solution for crude oil adsorption. [162][163][164][165][166][167][168][169][170][171][172][173] Gong et al reported a Ti 3 C 2 T X MXene-wrapped sponge (Ti 3 C 2 T X @PU) adsorbent, which simultaneously used solar heating and Joule heating, and enabled fast clean-up of leaked crude oil in the complex marine environment, and could function both during the daytime and at night. 169 Joule heating ensured that the heating capacity was maintained at night without sunlight or under cloud cover.…”

“…Wang et al developed a hydrophobic adsorbent via a facile yet efficient strategy, which had an excellent response to non-contact photothermal and magnetothermal stimuli. 163 As shown in Fig. 8a, a simple two-step dip-coating method was used to fabricate the Fe 3 O 4 /MXene@SiO 2 aerogel blanket.…”

Integration of phase change materials with multi-responsive halloysite nanotubes for efficient Pickering emulsification of high-viscosity oil

“…Fortunately, magnetic control shows obvious advantages of precise stereotactic operation and non-contact heating, making it an ideal alternative method for viscosity reduction of high-viscosity oil. 36,37 In the past few decades, the application of magnetic treatment technology in the eld of viscosity reduction of heavy oil has been rapidly developed. 38 The magnetization can destroy the intermolecular forces between hydrocarbon molecules in the oil, so that the intermolecular polymerization was greatly weakened, thus reducing the oil viscosity and enhancing its uidity.…”
