Abstract
The invention provides a modified MoSnano material and a preparation method thereof. The modified MoSnanomaterial is comprised of a hydrophilic MoSnanosheet linked with hydrophobic alkyl amine chain, the hydrophobic alkyl amine chain is provided by an alkylamine compound. The modified MoSnano material provided by the invention can be formulated into a nanofluid i.e. oil-displacement agent at a lower concentration, and is applied to the tertiary recovery in oil recovery, thereby greatly reducing the environmental pollution in the tertiary recovery, reducing the cost and improving the oil recovery.
