The alkaline earth metal cations-bridged polyoxometalate anions nanoclusters subnanometer nanowires were prepared through a facile room-temperature reaction. These nanowires could form 3D networks in the dispersion, and thus locked volatile organic liquids and formed gels. This finding provides a new strategy for safe storage and transportation of organic liquids and recovery of spilled oil.
