Desert beetle-like microstructures bridged by magnetic Fe3O4 grains for enhancing oil-in-water emulsion separation performance and solar-assisted recyclability of graphene oxide

Nature-Inspired Photoactive Metal–Organic Framework Nanofiber Filters for Oil–Water Separation: Conserving Successive Flux, Rejection, and Antifouling

“…The high rejection of oil achieved with remarkably good water flux can be explained as follows. The presence of the hydrophobic secondary building unit (HSBU) Fe–O atomic chain (in the form of trimeric iron) in MOF is favorable to attract micro drops of oil and the adsorbed oil coalesces to form macro droplets, while on the other hand, the hydrophilic nature of this MOF-induced fiber tends to detach the oil drops from the available Fe 3+ trimers , existing in MOF, thus completely avoiding them from passing through the membranes. From the literature it is found that MIL-100(Fe) has the chemical formula of Fe 3 O(OH)(H 2 O) 2 [C 9 O 6 H 3 ] 2 n solv, with Fe 3+ being 25.8% .…”

Solar‐light‐driven ZnO/biochar treatment of pesticides contaminated wastewater: A practical and computational study

“…The forcefield selected was BIOVIA COMPASSII 35 . The binding energy of BC with LM, MA, and OX adsorbed dodecane was determined using Equation () 36 $$${\rm{\Delta }}E={E}_{\mathrm{BC}@x}-{E}_{\mathrm{BC}}-{E}_{x},$$$ where Δ E presents the binding energy, E BC@x is the total energy of BC@LM, MA, or OX complex, E BC is the energy of BC and E x is the energy of LM, MA, or OX.…”

Recent advances in the applications of graphene materials for the oil and gas industry

“…Xu et al prepared magnetic graphene oxide composite as emulsifier, with beetle-like structures that endowed anomalous wettability. 63 It showed excellent separation properties for oil-in-water emulsion. In addition, Fe 3 O 4 and C-SR enhanced solar-assisted recyclability of GO.…”
