“…Nevertheless, employed absorbents, including inorganic mineral products [8,9], organic natural products [10,11] and synthetic polymers [12], commonly suffer from certain shortages such as low separation efficiency, insufficient buoyancy, slow biodegradability, poor selectivity and low sorption rate, etc [13]. To this end, it is of practical significance to explore facile, low-cost yet highly efficient approaches to fabricate oil-absorbing materials with excellent selectivity and sorption capacity [14][15][16][17].…”
